After Some Input Regarding Wheel Alignment

Hi I'm just hoping for some input with the wheel alignment settings on my r32 GTR. I'm looking for the best compromise for track days, hillclimbs as well as street duties - mainly through the hills. Iv just put on 255/40 17 toyo r1r tyres all round on 33 GTR rims. Suspension is lowered king springs and bilstein shocks. I'm unsure of spring rates but it is fairly stiffly sprung. Everything else is stock suspension wise. It sits at 345mm front and rear measured from the gaurd to the centre of the rim. I realize I will be limited by not having adjustable arms for camber etc. But just want some tried settings to aim for. The car has about 250 rwkw and a fairly tight LSD ( recently tightened up ) currently it chews the inside of all the tyres but the alignment could be anywhere at the moment.

I remember reading a thread from sydneykid about this but can't seem to find it now.

Anyone who has some experience with this I would like to hear your opinions. Cheers

Best to get an alignment. No point in us speculating what might be right / wrong with your setup. Scrubbing the insides of tyres is usually a toe-out problem, but it could be camber, which could be bad setting or shot bushes.

Get some numbers of how it is now.

Also, try contacting the guys at Whiteline for some advice re alignment settings (they have, or used to have, some recommended numbers for the 32 GT-R).

Cheers for the reply mate and the info about whiteline, i will look into that. Just to be clear I am getting a wheel alignment, just chasing some information regarding what camber, caster and toe settings to tell them to aim for. Hoping to find someone who has had success in finding a good compromise between track and street duties.

Thanks

I have a Stagea (different I know) with a similar setup - Bilsteins, TE37s with 255 40 17 tyres, GTR LSD. If nothing else you should try to get a heavier rear sway bar - it will make a heap of difference on cornering with no adverse effect on ride.

Toe in - you want zero front and rear with up to 2mm toe out front acceptable but none rear.

Castor - you want more than is possible without adjustable castor arms - I am running just under 6deg with adjustable arms so you want as much as possible with what ever you have. Short of new arms you can get eccentric bushes from Whiteline.

Camber - mine are set for the track with adjustable arms front and rear and about 3 deg negative (although there is no obvious excessive wear apparent so far). Again short of new arms you can get eccentric bushes but there should be little bit of adjustment available on your rears (not sure about the front) so you may be able to get 1/2 to 1 deg neg camber.

My set up works well for me on the road and on the track. I suspect it will work for you too but hopefully some GTR racers will share their settings with you!

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
