Title: Brake Disc Size
Post by: simon20vt on 07 February 2011, 18:14
What size were the MK4 Gti's front and rear discs?

Mines a 2000 W reg, ARZ engine code if thats any help.

I think the rear sizes are the same on all as far as i'm aware, but the front are different? 280mm or 288mm?

Cheers

I had my front and rears done at the same time with brand new discs and pads - so long ago i cant remember what the standard was like tbh  :laugh:

They are razor sharp though  :smiley: No im on standard brake lines  :smiley:

Most only do the 312mm fronts as the rear doesn't do much of the braking  :smiley:

+1
Had mine done in similar manner, uprated brake fluid, goodridge front and back lines, new mintex disc/pads. The increase is very nice, stopping is improved by a considerable amount and it bites alot harder!
