Default 2008 XKR with Alcon brakes
Hi all,

Can 19 inch wheels fit over the Alcon brakes?

It's doubtful, but you can try and know for sure.

There's very little clearance between the front 6-piston caliper and my OEM 20" Selena wheel. Your OEM 2008 OEM 20" Cremonas probably fit the same.

I think you need barrel clearance (diameter) of about 435mm so a 19" wheel could work with the right design, not stepped, probably CNC'd not cast or molded.

The brochure from that period says this for the Alcon option:

Alcon R Performance Braking System (only available with 20" wheels)

No chance with a factory 19" wheel.

I can barely get my finger between the caliper and the inside of the rim with the factory 20"
