I keep doing more and more research as well as talking to Matt Huffman(RX8) and DJ. Final alignment and moving to smaller wheels and tires below
Lower the car to 13-13.25" front. Same for the rear
Final alignment:
Camber F: -2.7 to -2.8 if possible at ride height
Toe F: -1/16"
Caster: Max
Camber R: -1.8 to -2
Toe R: +1/16"
After I kill these 245 tires I have on I'll change to some 245 all seasons and run the rpf1 daily. I'll be picking up either 16x8 FD wheels if I can find them if not some 16x8 SSR SP5R in SBC or some other color I decide on. I'll run a 225/50/16 RE71R until I move to a 225/50/16 Hoosier R7 or equivalent tire.
225 seems like a good sweet spot for this car weight and power for fastest lap times. Wider is fastest at autox but can definitely slow you down for overall time at the track due to fatter rolling resistance. Yes wider has more peak grip but it will be less acceleration and more weight. For racing wider would be better for more heat tolerance at a sacrifice for fastest lap. Where something like TT you want the single fastest lap time.
Anyway, other than that probably some cooling and basic maintenance is really hugely left for the car unless I do aero for TT5.
