Hey guys, getting my JRZ RS1 suspension buttoned down. The springs they sent with the kit has the car sitting too low for my tastes and versus GT2 specs. Replacement springs will be shipped from JRZ to bring it to GT2 specs. The shop I am working with originally recommended to replace the rear control arms that control toe since the car was so low. Now that it will be less low, I asked them if I can retain my stock parts for now and they would still be able to dial in toe properly. They didn't know.

My question is to you guys with 911 996 turbos at GT2 ride height - will I be able to have enough toe adjustment with the stock hardware for now? Or will I need to go with these aftermarket control arms to achieve what I want?

 

At gt2 height yes, if you run the aggressive toe of the gt2. If you want a nicer alignment to your tires then you will need them.

 

Thanks!

 

Amanda,
Every car is a little different but generally at GT2 height the stock rear toe eccentrics may not have enough adjustment in them to get the rear toe in check. The rear Motorsport toe arms are adjustable and makes setting up toe a breeze. I would get those. Excessive toe will kill your tires. Front adjustable LCAs are a must if you want to run more aggressive camber as you will only be able to get maybe -1.5 at GT2 height with the upper slots in the chassis tub. The higher your ride height, the less camber you will be able to get with the factory stuff. Hope that helps.

 

At GT2 ride height you need adjustable upper control arms and adjustable rear toe links to have enough adjustability to set the suspension up with a street compatible alignment. Toe and camber move inversely (take out toe you add camber) that the stock eccentrics cannot compensate for. If your plan to get above GT ride height you might be able to get away with stock parts or perhaps just the adjustable toe links. My guess if you keep it to X73 right height you should be ok. Of course you only want to do this once since the labor and alignment cost of doing it twice is no fun. So decide if you’re willing to sacrifice a lower right height to retain stock parts. Then set the right height so the stock eccentrics can yeild a street alignment.

 

Looks like I will go with adjustable rear toe links to be able to achieve the GT2 ride height. Thanks guys!

 

Gt2 and turbo have the same wheel carriers, lower control arms, toe arms, and upper dog bones. Knowing that if you lower a turbo to gt2 height why would you need to change parts that you would not change on a gt2?

 

My car has 1" lowering springs which puts me close to GT2 ride height and I've got stock toe links, control arms and stock wheels. My tires wear pretty much perfect straight across the rear tires. I wanted a bit more aggressive alignment than factory for better handling in the twisties anyway so achieving stock alignment wasn't my goal. In the rear I'm running a bit more camber than stock alignment and toe is pretty close to stock alignment. If you are worried about tire wear, too much toe will chew up the very inner edge of your tires. Extra camber equals a slight gradient from outside to inside with the inside wearing slightly more. Just my experience.

 

Tim,
Perhap I should have qualified my answer with one more clarification. If you're running stock 996TT wheels and tires you maynot have an alignment issue that cannot be corrected by the stock eccentrics. I should have mentioned that I'm running 315x25x19 on 12" rears with a rather radical offset. This compounds the problem of too much negative camber and toe in for street use. The front has not been a problem but we should note that suspension pick up points on a GT2 front are different than a AWD996TT.

 

19'' wheels explain it. The pick up points are the same on the front end for the turbo and gt2. The wheel carrier is very different though.
