I am fitting two GTDs with new brakes all round at this time. 6pots on fronts,4 pots on rears, mechanical or hydraulic handbrake. I use both AP and much more economical but equally as good brakes from Hi Tech Engineering, Dartford, Kent UK. I have been working with Hi Tech to develope ready to fit kits for these cars. Currently fitting 340mm Discsx30mm 6 pot calipers to front 17" wheels, and 330x28 4 pot calipers to rears. I do not use wilwood as I consider the cross bridge too weak, and have experienced problems with them on track (Dynalite 2s). E m,ail for further info. Frank
