If you are running true semi slick and only driving it on a race track I agree, anything else and imo the slightest bump and you'll be getting wheel spin.

What dampeners are you running? The issue with most 8/6 rates is they come in a coilover kit with crappy shocks.

That doesnt mean the spring rate is wrong. It means your shocks are too rubbish for the level of performance/grip you desire

If you are running a POS pogo stick brand of shock then it doesnt matter what spring rate you throw at it...it will be rubbish. Run a basic Bilstein or Koni and get them valved to suit a higher rate spring and it will be fine.

I run Tein RAs, was going to revalve my old Bilsteins but grabbed these as they have allow bodies. My car doesnt get wheelspin even in second on the street. Good tyres, good alignment and reasonable quality shocks and you can put 300rwkws to the ground without a lot of fuss.

Dont see the point of running the cheap coil overs. If you are spending $1200 may as well save up and spend 2k for a far better result. Then you can run whatever spring rate that suits the grip of tyre you run.

Yep, I run DMS 9kg front, and 5.5kg rears. Interestingly for the 32 GTR this is their (DMS) "targa spec" rates with valving to suit. So more of an all-rounder than a straight circuit setup. You certainly can't afford it to be drifting or spinning wheels in a Targa event I assure you.

And it feels very sure-footed - still with some good compliance.

As Roy points out, a good deal has to do with valving too. I think a lot of people try to 'over dampen' - using the shock to 'stiffen' the ride.

Good work Simon!

With all that new found grip out of corners I definitely will not be giving you ~any~ head start onto the front main straight at next years Powercruise... ;)

Grip ftw!

Like you gave me any head start this year! haha

I think by the time powercruise comes around I'll be running MT Streets on the rear to scare the GTR's :)

You are right, I'm guessing Simon isn't running bilsteins or a decent shock though, didn't he say he was running a jap coilover unit? Even the 'good' brands are still average from what I've heard. How does the tein hold up compared to a new bilstein? Not first hand information but people told me that there was no comparison, how true is that?

Looking at the times Simon's car is doing then I dont think there is that much wrong with the Greddy Type S shocks he is running. An S15 did an easy 1:44 at PI the other day with Greddy Type R shocks, before its engine gave way. So again must be reasonable if doing those times so easily.

Simon's thread isnt really the place, but I think Tein make fair, good and very good gear...Off the shelf Bilstein are a good flexible product, that can be valved to suit pretty serious applications. Just like ECUs and tuning, if you are going to play with suspension best put your belief in the shop that has runs on the board with that type of setup with plenty of proven results

:) Well read your signature... 135mph?? Sheesh! You get NO head starts..! ;)

132.5 not 135 haha

You have no idea how emo I was after getting chopped by the GTR's all weekend because they were gassing second gear half way through the corner... I was lucky to get traction in 3rd in a straight line :domokun:

Yeh, so many S13/R32s etc all complain about not being able to get 180-200rwkws to the ground and these days I automatically assume its because they run "fully-sik" all sub frame bushes.

Ill just say here ive converted to s14 rear cradle in my 32 with alloy craddle bushes and this a has 5x the amount of grip and stabillity the car now has so in some cases alloy sub frame bushes will work i mean full alloy bushes though not the lil c looking ones.I was very impressed with the grib and stabillity it has bought back alot of grip

That was my original plan but lack of time and extra effort put me off... I may end up going that way one day if I feel the need!

What kind of subframe bushes/alignment were you using before the swap? and also how much extra NVH are you getting with the solid bushes?

but what did you convert from..

i mean does it have 5x the grip of an already good setup or was yoursetup all wrong in the first place...

That's what I was hinting at... If he has gone from Whiteline "maximum traction" setting to this and thinks he has got 5 times the amount of traction I think I will have to make the change :thumbsup:

Just dont tell too many people in Vic that simple bushes in the rear ends of S13/R32 is the way to go for great traction. I am posting vids of PI up this weekend. You will be amazed by the power down in 2nd gear with attitude on the car. Keen to see you vids...your times are mighty quick

I was fairly happy with the times considering it's a street car with no cage and full interior etc and probably the worst aero in the world haha. I'm going to purchase a Gopro Hero2 when I get back from my holiday :thumbsup:

Well looking at those fancy R32s, Series 6/7/8 RX7s and S14s etc running around in your Improved prod class, they are only doing 1:04s! And from memory all the big bangers in the top 10 at the WA Dutton Rally were generally only 62 sec mark

I think there would have been a 65 in it with a bit more practice but I was still tentative on the brakes after I went off backwards into turn 1 last time I was at the track.

The last lap of the weekend I was going to do a balls out lap with around 50 extra hp plus 500rpm to see just how that would go but alas it blew the cooler pipe off as soon as I got on the gas along the main straight haha :pirate:

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
