I have a 93 240sx I am building and was wandering what spring rates I should start with? I plan on running at Atl. Nash, BIR, Sebring, VIR. and maybe a few other tracks. I have ran BP. & GT1 corvettes till now so these cars are new to me. I have Whiteline sway bars. I have 205/50/15 R6's but plan to run 225's when I get thru with testing. What starting camber angles and toe settings for baseline. Any help would be great.
