318ti rear BBK
 

Seems like a vendor finally got around to making a Ti specific rear kit using wilwood calipers. You can choose to use either the forged superlite 4, similar to what I have on the front of my car, or you can use the lighter dynalite caliper. But it would allow you to upgrade to rear vented rotors.

I emailed the guy making this kit and his take was that to use this properly you would need a brake bias valve to adjust the front/rear brake bias.

"12.2" x 1.25" lightweight rotors (UL) and either Superlite (1.12" pistons) or custom SL4R (1.12" +1.25") calipers."

you can get rear trailing arms from a z3 or mcoupes for alot cheaper and it does the same thing

Is the Mcoupe rear a direct replacement for the ti rear trailing arms?

Any swap that I have ever heard of to m-coupe trailing arms also had the subframe replaced as well.

If you want to use the brakes from an m coupe/roadie best to get the entire rear subframe, trailing arms, brakes, etc.. and go from there. Price on those is between 1000-2000$ if you can even find one completely intact.

And then you still have used parts.

That's what I've been thinking.

Not worth it.

hmm, if anyone is doing this. . .I need an original intact 318ti subframe + trailing arms (well, just the driver's side one).
