I run ATE grooved discs and Pagid on the front
Pagid discs and pads on the back. all from ecp.
Be careful when you buy from ecp as they did have Mk3 gti brake discs listed wrong, size and studs.......
Take your old one in when you pick them up and compare

The green stuffs i had on the front cracked through the lining in the middle

once bedded in the pagid FR are better than ebc imo
