Biiggest brakes for the S1 oem wheels

Looking around for the largest setup possible using oem braid 716 8.517 rims for the S1 .
I have been told ap 4 pots and 330mm rotors on fronts
but only managed to spec 310MM with GSM brakes
or 315MM frt with Pilbeam kit …
Anybody got some feedback on this ?

Yep, JSR have a car with 330mm front brakes and AP 6 pot callipers that fit under Braid 16" rims.

The kit was developed by JSR and is available with 4 pot or 6 pot callipers.

Give John a shout.
