Not sure how many on here still autocross their Z, but is anyone excited about the tire changes for STU? I am as the 265/35/18 Yokohama's while fast, don't allow me to run a wider tire than the AWD cars in the class. Previous years I ran the 275/35/18 Bridgestone RE-71r but the Yoks are just a bit faster.

I'm hoping I can get at least 295/30/18 to fit with goals of squeezing in the 315's. My Z is quite low so I may have to raise is slightly.

 

Good luck- I race my Z in SCCA road racing and the current rules in Touring 3 limit us to 245 max width tires. I also put in a CRB request last year to classify the Z33 in the D2D STU class, but this was NOT approved.
