JAGUAR XK8 - XK8 Wheels

Q
I recently replaced my 2000 XK8 with a 2004 model which, surprisingly, has 17in wheels. I am considering upgrading the wheels/tyres to either 19in or 20in. Are there any adjustments or modifications required to fit these wheels?

A
All XK8s can be fitted with wheels up to 20in without modification providing they have the correct off set for that model. Problems only arise when fitting the smaller 17in wheels to cars with the Brembo brake upgrade as there is insufficient clearance at the caliper.
