Just out of interest, I emailed the seller on the OP's original ebay link to ask what parts he was supplying, as the ad only said:
This set consists of :
· 2 x OEM Brake Calipers Natural, Red, Black
· 2 x OEM Brake Caliper Carriers Natural, Red, Black
. 2 x 312mm plain front brake discs
. Full front set of brake pads
I wasn't sure if the discs and pads were going to be cheap and crappy. He has come back with;
"yes the parts are genuine vw/audi and the discs and pads are EBC branded products"
Does this give any indicator as to whether they will be any good or not?
Also, I assume no issues with going for 312mm brakes with the standard 16" Monty II's?
