FYI - cross post
 

650# up front? What did you do to the rear?

Stock back there, wanted to be soft enough to take advantage of the LSD.

When autocrossing, I run soft hoosiers 225 front and 245 rear, it stays on line nicely!
Very minimal push, though flat as possible. Keeps the front firm under braking as well.

Huge improvement over the way it came ... open diff and lots of tire smoke :)

Still available... Plus, some tools (timing belt tool kit and timing belt) can be included.

I will make smaller ones for here, but if you wanted to see bigger versions.
thanks!
