I have just purchased an old stock TSR 280mm conversion kit for my MK2 Golf, and am looking at getting the adaptor brackets that move the calipers out to accomodate the discs re-manufactured as these are no longer made by TRS ot anyone else that i can see.
These brackets if you don't know will allow the use of your original caliper and will fit MK1,MK2 Golfs and Rocco's and Polo's 2 and 3.
Price will be reasonable and all you will need extra is G60 280mm discs.Original kit inc the discs was £279:00!!!
Let me know if anyone interested,
Cheers,
joe
