Ive got some brembos and they are so much thicker that they would require the disk sitting in too far to be possible on a nova without going to a massively different offset of wheel, which is why I didnt use them myself, but if its on a cossie its a pretty easy fit etc.
What car is it for? If its your nova I think you will be dissapointed!
If you can be bothered to pop down to somerset one weekend I will show you if you like?
