Hi guys. New to rennlist, and need some help !!
I have a 997.1 gt3 and drive on PPZs. Rarely use on track and enjoy driving daily. Recent tyre replacement and alignment has created a front end monster at speeds >90km/hr,with poor directional stability. Alignment is stock gt3 setup. What would be best toe/camber/caster for daily driving ? Thanks

 

What were the actual final numbers from the alignment? Stock specs are generally best for a street driven car BUT it still should be done by a good shop (generally a race shop). Toe is usually the number that is off when the car feels the worst. The cars are exquisitely sensitive to it. For straight line stability on a street driven car, you want a little toe in in the front (should be a positive number) and you want considerably more in the rear. The rear toe should really be identical side to side (within 1/100 or no more than 2/100 of a degree). Otherwise, when you get on and off the gas, the car will literally jerk back and forth, most unpleasant.
