Yea I do need it for sure but im not going to worry about driving down to get it and all that though. I dont really feel like working on the car saturday, down there with no tools just to run a 2.5" pulley. Ive read a few threads where people mostly say they dont really gain much of anything going from a 2.7 or 2.8 to a 2.5 so im thinking its not worth the work. While were down there for the races I would rather just leave everything ready to run and sit around and drink beer instead.
