Car is ~3100lbs, 3.29 gears, 3800 series 2, 206/206 .512/.512 cam, stock heads, with 6262 turbo, precision PT-1001 Air to water intercooler. Up until now I have run a M/T Drag Radial 235/60R15 26" tire. Thinking I should mabey run a taller tire with the turbo setup. Pretty sure I can fit a 255/60R15 27" without changing anything. To go to a 275/60R15 I would probably have to change to coil overs, and be trying to figure out spring rate to make everything work again. Car has gone 1.54 60' with a M90 blower setup at 345 RWHP on mustang dyno. Ran 11.42 and best MPH of 117.x. The turbo setup is making alot more power, shattered my 4340 input shaft within 5 days of getting it running. Built tranny back up with a 300m input shaft now, hopefully it holds.
I guess the question is, will a 27" tire be enough, or should I try and make a 28" tall fit?
