Braking improvements......??

Will these fit under a standard set of Volans or will I need to upsize to 18" wheels??

Anyone had any experience of altering the calliper carriers, if so are they a bespoke item or can I get a set ordered from Volvo etc.. to fit on my 850 R

Opinions please.

Cheers, Morgan

The P2 stuff is very difficult (bordering on impossible/too expensive to be worthwhile) to fit to the P80 stuff mate.

Oblark had Megane 225 brembos and 320 disks on his but it took a fair bit of work.
