Anyone know if it can be adjusted in front? I bought some taller tires than stock and they rub the front fender liner, i would like to move the wheel back a little bit.

thanks.

 

Yes. You have to replace the thrust arm bushing:

I did a bit of a write-up on these over on renntrack...

Here are a few pics... So much easier to install them with a press and the control arm off the car... takes less than 10 minutes to do a pair...So it as I did below, and who knows...10 minutes or two hours... One small bur can really hang you up.

DIY Install of Thrust Bushings

I bought adjustable thrust bushings and did a search on how to instal them... Nowhere did I find one...so...

OEM Bushing, ERP Bushing and Stock Control arm:


The tools I used to press out my bushings:


You also need 18 and 21MM wrenchg/socket tools.

Heat the bushing steel sleeve (the part the rubber resides in) for about 45 seconds to a minute... Then take the hammer and the seal driver and drive the bushing up...



Installed Bushing:


It's pretty simple to align the new bushings and have them ready to install the thrust rod onto the control arms.

These units help in re-aligning the caster when you adjust for much more camber for track use.

Thanks Mike, you are always of great help. I just realised that moving my camber isn't going to work since i tried to turn the wheel completly, the rear of the tires touches the fender too so i don't have any choice but to live with the fact that 255/35/19 is just too big for the front.

What i don't understand is that it should have been only 0,5" higher in diameter than my previous tires, which means ony 0,25" per side, it looks more like i added one inch on each side...

 

I'm running 255s on my CCWs in an 18 without issue... They pulled back all the added caster very well... No issues...It's not the camber, it's the CASTER... to much positive caster...

Pumalex is on 19's, which is adding another 1/2" on each side of the axle.

 

yeah exactly, but i now realised that adjusting caster won't help, it is rubbing in the back also when the wheels are completly turned. I didn't try it before.

 

I missed that in the earlier read... Sorry guys... This is another good example of why I don't like running 19s on a 996TT.

yeah the tire choice is so much limited... Let's just say i wasn't to much into lapping when i bought the wheels but now i realise what problem it creates.
