I just fitted Pagid front discs on my 8v, good discs good price but be careful buying from ECP as i had to spend a good while convincing them gti's were 5 stud and not 256mm........
Check their site it specs 4 stud 256mm discs for 8v gti 
Yeah, their site is quite confusing.
I still don't get it, which Golf's came with 256mm discs? As standards are all 239mm, aren't they? GTI's 280 and 288, and VR6 don't remember, lol...
