Parsonii how long have you had the wheels and tires on your car that are supposed to ruin the front diff? I keep hearing it, but keep seeing guys running 19's.
Doesn't the 997 have 19's? If they do, how do they do it? Or are they 18's as well?
Wheel size doesn't matter - it is the overall diameter of the tire/wheel assembly. The issue is actually with the center diff when the front and rear rolling diameters are of too great a difference. This difference in rotational speed will cause excess wear if it is too great. I have read that we should stay within 1% difference on the 996 TT (stock is 0.4%), but I have no official source for this.
The 997 TT has a revised AWD system and can handle larger rolling diameter differences front to rear. Stock front and rear difference on the 997 TT is 3%.
thanks! i think your car would really look great with a titanium or hyper silver. GL whichever way you decide. just don't mess with 19's. for what. 18's and lower it. cheers.
