So I’m not taking any chances so the AS/3+ will be the rubber for this trip. The ZIII’s are great but one dimensional. Temperature fluctuations, gravel, rain and possibly snow may be encountered. Since I’ve already run these tires I know what to expect from them and their versatility will be depended upon. Now that the car has a better suspension and it’s lower, I feel they will perform even better now. I personally think the AS/3+ is a fantastic tire. The AS/3 I had on the stock car would get a little spinny down low. We’ll see how these handle 300+ hp and a linear powerband
