The rest of the package should be up to snuff. I'm not changing my trans or diff right away, because then I will need a custom drive shaft, which get plenty expensive.
The pilot bushing for the trans input shaft in the engine crank must be changed to accept the larger imput shaft of the ti trans. Other than that, no problem. It bolts right up.
The diff is the weak link, but should hold up fine unless you are dumping the clutch from redline or something stupid like that. E30 M3 diff is VERY similar, but the axle shafts must be "customized" for the instalation. Not too difficult, but the E30 diff does not just "bolt right in".
Brakes are a big issue. The easiest way to solve a few problems at once is to get complete struts with springs and spindles, calipers and rotors from an M3 4-door (2-door will probably work as well) and bolt the whole mess up. This is what I'm planning to do. This way, you have the heavier springs for the weight increase, as well as the brakes. AND, it all bolts in! |
