[QUOTE="kevinatfms, post: 16046441, member: 39344"] New shoes came in and tires mounted. This setup is 5lbs lighter per corner than the current wheel/tire setup. 15" Sparco Terra in Bronze with 205/50R15 Federal 595 RS-RR's. The wheels are hub centric and tick the scales at 15.6lbs. I plan on putting them on this weekend to run around and get a feel for them. They are a 200tw tire so grip should be about the same as the RT615k's i have on the FRPP wheels. More sidewall will introduce more flex so it will be interesting to see if the steering loses some precision. The tire is also shorter than the current Falken by .4. So i will use my Cobb AP to change the rotations per mile to match. I hope the gearing isnt too short for a higher speed autocross course. On our short course it should really help though and that is mainly where i run my car. We do run at one venue that is quite bigger and i might have to swap back to the 17's to get the speed in 2nd gear. We will see. [/QUOTE]
