Not having luck getting my front NT01s to fit on my track car. They work fine on my DD but it's about an 1.5" higher off the ground. The front wheel is running against the coilover. If I use a 6mm spacer I have lying around then it rubs the front when I turn instead. Any suggestions other than running the z214s that work fine?

Nt01 wheels are about 6mm different in offset so the spacers were perfect. But they are 20mm wider than the z214 in the same size. So annoying.

Z214 - 245s measure 240mm
NT01 - 245s measure 260mm

245-40-18 work great in the front on my car. 108 mm front height. 2.25 camber

Ya, I'm missing something. It's got the same ride as yours which is the same as my silver one that these work great on.

So does driving on z214s to and from Autocross count as a heat cycle each way?

What tire size? What wheels? What offsets?

Me: 235/40/18 - 18x9 - 53ET +7mm Spacer

Work fine

My wheels are 18x9 with similar offset (it's not marked) but I have 245/40/18 tires.

You might have too much caster.

I didn't get the specs on caster but camber is -3.2 and it is only -1.8 on my silver one.

Ya, I think the 235 would give be me the extra little Bit of clearance.

Does it have split control arms with more than 10mm of shim? If it does, and there is not an adjustable puck or threaded thrust arm, I bet it has too much caster.

Slakker

It does have at least 10mm of shim on the GT3 LCAs.

Ok, got it. So the Camber has them rubbing against the coilovers and when I use spacers to compensate the caster has them rubbing against the front.

So is an adjustable thrust arm bushing the best solution? Will that require another corner balance or just alignment?

I would say an adjustable thrust arm is the best solution but adjustable pucks are cheaper and will work. Technically you can't really adj camber/ caster without changing your CB a bit. But theres a more than good chance you wouldn't notice the difference if you just did alignment.
