Re: Make into Track Car, or sell along? advice?
The 315s square make it handle great. It's easy to overdrive the 275s. The 315's will balance it. The 56mm offset 17 inch wheels will fit the front and the rear with spacers and can be rotated. They...

Re: Track Day Brake Pads
Yes, it was 4 piston.

Re: NASA HPDE Newbie
