The car no longer runs on star specs. Instead, those are the street tires. I’ve since started running 17x9’s up front and 17x8 in the rear. I am using Hankook Z214’s in the C71 Auto-X compound. 275/40/17 front and 245/40/17 rear. The difference is unreal. The car grips and grips. I have only been able to run it once on this setup, but this upcoming season it should do well.
