These are the same as off a Golf GTI 16V and if you change the rotors and caliper carriers it’s a short step up to 280mm stoppers.
What I’ve got is a pair of complete hub assemblies, up to the flexible hoses (which are cut). There’s plenty of life in the pads and discs.
£65 for them. Collect from Bristol, or I can drop off this weekend along M4 Corridor to Tunbridge Wells. You should change your standard brake master cylinder for the 16v/Rallye one when you make this upgrade, but they ‘just bolt up’ and if I recall correctly are the biggest brakes that will fit under 14″ rims – definitely a worthwhile upgrade from the horrid 239mm discs on a UK spec Syncro.
