Hey Nicky Good luck at VIR next weekend. While not as radical as your build, winter weight reduction is planned including race seats, 1/2 cage, lighter rotors, etc. My goal is 3500#s and my latest retune eliminated an occasional power loss and likely found another 20 rwhp. :-) Since I'm running rear spoiler w/adjustable wicker but no wing, will a diffuser still help?
