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:

    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option
