My buddy got them on his stang with slicks on them, and just wanted to know if they would fit on my car for a few passes.

from what i understand you cant put a 15" wheel on a TT rear end anyways because of the brakes?

In order to fit 15" wheels you're going to need NA or Lexus rotors and calipers. AFAIK the lines will bolt right up.

If only it were that simple to bolt them up:( I wonder how much braking power one would loose by down grading the brakes. Everytime I think about doing it, I remember I don't spend that much time at the track to begin with.

A few guys have claimed the braking doesnt change much.

I have heard the same. A local guy to me (Rviscosi) is changing his fronts to NA's so we'll see how much it changes if noticable at all.

I have NA brakes (since my car was NA to begin with) with Weld Prostars on the rear and Monocoque skinny's on the front. I imagine the NA brakes aren't as strong as the TT brakes, but I haven't had any troubles at the track slowing from 135 mph. Roadracing would probably be another story....

i dont think you would notice swapping the back brakes that much.. now if you swapped front and rears, that i'm sure you would notice..

I seriously doubt that N/A brakes in the rear could ever be better than the TT set-up.
That depends on what kind of pads you are using.

I guarantee I can put a set of race pads on an N/A rear setup and stop shorter than a set of pep boys pads on a TT rear setup.

The N/A rear Rotors are not that much smaller than the TT's

Also for those of you that do not have line lock it makes it much easier to do a burnout with big sticky M/T's with smaller rear brakes

My Welds bolted right onto my MKIII also. You will need more than 4.5" backspacing tho. I believe mine are ~6"

5x114.3 is right. I have 27x10.5-15 Hoosiers. They would just barely rub on the fender lip on a hard launch. I'll see if I can dig up any pics of the wheel/tire combo on the MKIII. Here they are on the MKIV:
