Hi all, So my GTX has been sitting patiently off road (gubbed cylinder head for the past 3 years now. I've decided to break my MK4 Golf Gti as the residual value is just poor for it depite it being in good condition. I'd like to stick the rear brake calipers on the rear and convert to discs. On the Golf I had running 256mm rear vented discs. (Anniversary setup) Are these a straight swap onto the 226 mm rear discs? 1. Can I use the caliper and carriers for this conversion? 2. Upfront I have the standard 239mm setup. I'd like covert these to 256mm as I would hopefully be able to retain my 14" wheels, possible to do I believe.... I would like to use the vauxhall caliper setup front however I seem to be struggling tracking down part numbers etc for this especially the carriers. 3. A 22mm master cylinder would be my my final modification in my thinking and some sort of bias valve fro the rear brakes as weight on the rear corners of the rocket is half that of the fat Golf. Would that setup be capable of stopping the Engine when she goes in? An AGU with K03S and stage one setup (approx 190 bhp). Any help would be appreciated.
