Just wanted to get some ideas from those WHO HAVE driven there skylines HARD on the track.

I have a series 2 R33 GTS-T with plenty of grunt and plan on getting serious into track days in VIC. I have run my car when I've been instructing at Phillip Island and at Winton but have realised it has a few shortcomings.

Number One. Running out of brakes.

Ran out of brakes at 260 odd clicks at the end of the main straight at the islkand and was not too impressed. Managed to get it down to about 210 and sllipped it through turn one to tell the tale. I have since put in Race Brakes RB pads, Castrol SRF race fluid and slotted rotors, rebuiolt the booster and the master as well. I plan to also put some ducting in as the series Two has two nice big free vents in the front bar.....

Any other suggestions for brakes......

Number two: Suspension set up.

I have Nismo shocks which are passed it, king springs, urethane bushes, camber kit F and R and a subframe lock kit as well and front adj castor.(urethane). I plan on some whiteline adjustable anti rollbars and want to upgrade the shocks to either Koni's or Bilstein...

Any thoughts or experience with the Bilsteins or koni's??

I can also get a hold of some TEIN coilovers as well but have heard they are ultra hard and my car is a daily driver.

Lastly, any suggestions on a road/track alignment that will give reasonable handling withoiut totally chewing tyres. I currently have too much understeer and the back end has SEVERE bumpsteer on the road. Dunno if anyone has experienced this with their car but when I hit a bump, the whole back end moves sideways.....

Also to HICAS or to lock it up....

Any thoughts greatly appreciatted but please, only from those of you who have actually had experience driving these hard on the track and know what set up works....

Lastly, why aren't there more skylines out on the track, there's so many on the road........

Thanks

Hi James, there are plenty of Skylines on the track you just have to be there at the right time.

HICAS is not your friend, get rid of it. Do a search on other stuff I have written on HICAS and why it's gotta go.

We run Whiteline adjustable stabiliser bars, 27 mm on the front on a GTST and 24 mm on the rear in the dry and 22 mm in the wet. Ordere them with one extra hole per side, std is 2 you need 3.

The standard diff is not a good track device, we find a 1.5 way clutch pack mechanical to be best. ATS make a good one, as does Nismo.

Alignment settings are really dependant on rubber and spring rate. We use 3.5 degrees negative camber on the front, with 8 degrees positive caster. Between 1.5 and 2 degrees negative camber on the rear. I usually run the alignment on the race cars straight ahead front and rear. If you find the rear a bit fidgetty under brakes, a bit of toe in helps with stability.

Decent R compound tyres are really a must, R33 GSTS's are heavy beasts so need plenty of grip. Our control tyre is a Yokohama A032R, we use 245/45/17. The Dunlop and Bridestone equivalents are arguably slightly superior in the dry.

You will find as the corner speeds increase, the brakes won't be such an issue. We use Hawke carbon pads in the blue compound with DBA slotted rotors and AP 600 brake fluid. Remove the backing plates from the rotors, the fronts bolt on but you will need to cut the rears off. An air saw is a big help.

For track work the Bilsteins are very effective and give good value for money. I have yet to find a Japanese damper that gives as good a result. Ohlins are also very good if you want some adjustment to play with. The Konis don't have quite the piston area for track work, great for the road though.

Keep the rear spring rate low, not much over 200 lbs and control the roll with the stabiliser bar and the squat with the subframe bushes.

Hope that helps :D

:werd: particularly re the brakes, I did phillip island for the first time, and even if you were heading into turn 1 at 260, you don't need to take more than 60 off your speed so unless there is something wrong with your brakes the stockers should be fine with good pads and fluid.

My stock brakes survived 4 years of track days without problems except when I used EBC greenstuff.

I don't think you mentioned anti-roll bars? you should look at some uprated adjustable ones to keep the car flatter. We also use the bilstein shocks.

And, you should have come out on the weekend, there was 7 of us at the 2 super sprints :P check out Vic events, I think the next one is Sanddown.

Brutus.

I have just completed my 4th day at Phillip Island and have driven my car pretty much as hard as I can (as a lap time of 1.49 shows! LOL)

I can't give you a complete answer for a rwd car BUT there is another GTR that has been coming with me that is set up almost identically except for brakes and suspension that is about 3s slower around the Island. (and its not in the driver!)

My brake set-up is:

Fronts - DBA 5000's - Freodo 3000 pads

Rears - DBA 4000's - Comp 2 pads

Fluid - Castrol SRF.

I had previously been running standard rotors with endless pads - and the difference when I put in the Ferodo's was MASSIVE. Even after the 8 lap practise sessions on the Saturday of a PIARC weekend I wasn't experiencing any fade. The bad thing about the Ferodo's for normal driving is that they are DAMN noisey. But on the track I think they are awesome.

As for suspension I am running Tein HA's. I peronally don't find them bad on the street at all (I keep them on my track setting as well always) but then I also dont drive my car every day. But compared to Scotsman who is running stock suspension I can carry about 15km/hr more through that last sweeper coming onto the main straight. There was a guy with a worked WRX last weekend that dropped 2.5s of his previous best time with some whiteline suspension.

Also - I am only just starting to become a half decent driver and last weekend was the first time I noticed the HICAS doing things that were upsetting me. skylinegeoff from the forums here makes a locking bar - I have one on order now.

I am also going to look at running a bit of camber. Have been running nothing but really noticed the wear on the outer edges on my tyres after last weekend. I am going to go down and speak to Ben at Racepace about any set-up suggestions.

As previously mentioned - there is a large group of us running at the Maserati day at Sandown on October 24th. Think 15 from last count. Check the Vic events section - be good to have another Skyline on board.

Come on James, we are in dire need of a few tough GTSts on the track, these GTR boys are starting to think they are untouchable.;)

Brakes sound much liek my setup, and i have never had probs, though i have never been to Sandown...im following Snowmans lead with the Ferodos for the nextr track day, as my RB74s are dead anyway

For me i think my car is a great compromise between daily driver and weekend thrasher. Whiteline spring and Bilstein shocks work well, some think my car is too rolly and doesnt "handle as good" as some cars with stiffer spring rate / coil overs, but im pretty sure my car has pretty good levels of grip. :P

As others have touched on, susp settings are very dependant on your ride height, tyre selection, and other susp mods. A Bit of adjustability with bushes is a great thing, speak to a susp place that aint full of hot air and get some feedback from them.

Thank you all SO much as the responses were exactly the sort of info I was after.

I put in a set of RB74's from race brakes yesterday for the interim and they certainly seem MUCH better than what I had. I went for a really hard run DOWN the kinglake road today and got no fade. I previously ran the HAWK blues in my MX5 and loved them but they are about $400 for the GTS-T.

I will get a HICAS kit on your suggestions and also get the swaybars. Are the extra holes closer in (stiffer) or further out (softer)????

Lastly, I wish to run soon but need to (want to) get an oil coller in first so she doesn't go bang after 2 laps and also getting married December so spendings on hold. Hence taking my fiance's MX to Winton this weekend for a thrash with the WRX Club.

Andrew, I presume your running in a GTR???? My aim for the Skyline is to get into the 40's if not mid 40's but I'll have to wait and see. I do kow when I was instructing with the BM club I took it for a run and only had piddly 225/16 track tyres and no brakes and I was hosing race prepped M3's driven by the experienced BMW guys. Felt like I was doing low '50's at the time.

Best previously was 2.04 in a bog standard MX5 on road tyres and 2.00.18 in an mx on track tyres with koni's.......

Could never better that 2 minute barrier in the MX no matter how insane I drove it so that's why decided it was time for a quicker car!!!!!

If any of you guys are at Winton, look out for me, I'll be there with a dozen other MX5's.....

As for the GTS-T's, all that i have seen at track days have been running around 5-10 secs a lap slower than I did in a stocky MX5, that's what I was confused about......

LOL...now you have done it. Im getting caned bacause i think i can easily get under 1:30s around Sandown, and im aiming with enough practice to get close to 1:25, a point Andrew is sure to remind me of if i fall short :P

If your car is sorted then i dont see any reason why you cant get into the high 1:40s arounf PI, hell i did maybe 10 laps with car probs including ignition woes meaning i was running on 5 cylinders and wasnt even really linking corners, just trying to suss braking points and turn in/exits and i still did a 1:58 ;)

Now thats far from 1:49, but im confident if my car was running on 6 cylinders and boosting properly i would have have been around 1:53s. Then with some practice / experience of the track try and dip into the 1:49s, but ppl will tell you it aint possible becuase its a GTST :)

Oh well the fun is getting out there and trying. What times are the M3s doing?

RaceBrakes have a brake pad compound that is better than the RB74, I forgot the model name but give them a call. It was something like $350/set compared to ~$150/set of the RB74's.

Cameron McConville did a 1'52" at the island in a stock E46

on slicks.

but still, great effort :P

And, there is absolutely no reason a GTST can't keep up with a GTR so forget that idea :slap: 4wd is of least importance at a track like phillip island where there are few low speed corners to have a traction problem ;)

Give me a lighter car with about the same power and there'll be a faster lap time.

I also remember Cam McConville doing a high 1.43 around Winton long track in an STI scooby a few years back. I had never driven one before and instructing, i did a 1.41 in one on my second lap with a 100kg passenger and a full tank of gas in a totally standard STI.

Also, Larry Perkins only did a 2.11 around the island in a stock , road tyred MX5 and I did a 2.04, so I guess times aren't that comparable day in day out, although I often wonder what exactly LP was doing that day????

My best time at Sandown in a stocky MX5 with 032R's was a 1.33.9. The only timed runs I have at the island in the GTS-T was a 1:58 but that was totally stock on road tyres and I was taking it pretty easy, first day out and it felt like it was losing about 100kw in heat soak after half a lap with the stock cooler..

Can't wait for Winton saturday, haven't played on the track for two weeks.....

And that's two weeks WAY too long....

Oh...Any reply on which way the holes are on the anti rollbar. ie drill extra holes in for stiffer or extra holes further out for softer????

210 through turn 1 in a road car ???????

Thats only about 15 kmh slower than a v8 supercar !!

meh, the honduh could go in at 180 on crappy road tyres, I'm sure 210 is possible on r tyres, and I suspect a supercar is going over 230 (but I'm happy to be corrected)

that turn has good camber and is much more open than it looks

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
