15 inch wheels over 4 pots ?

[deadmeat]

Hi All,
:confused: Does anyone know if I can fit standard 15in wheels over 4 pot calipers on my classic?
Got 17in Prodrive alloys, and a 4 pot brake upgrade on my classic when i bought it but looking to get some 15in cheapies to do some playing at the local airfield.
Cheers

If the disc is over 288mm no chance i had to get 16" wheels to fit 300mm 4pots on the 309
