These are 356mm 8 pots but you can get 330mm to go under 17in wheels and I did paint them but you can get them in red now, pads are ds2500.
I think the old ones are about 300mm
Handling. Front strut brace ,Front and rear ARB's,Drop links,Anti lift kit with Eiback Springs which will give you a not to hursh set up.
Map, I did this first,Walbro fuel pump,Three port solenoid,Air filter,uppipe as the bug has a cat in it and for the exhaust I have a Hayward & scot with sports cat and Afterburner Vortex and that will give you about 270/280hp and a very nice road car .
