I have a 2003 XJR 4.0.... I'd like to replace the calipers since there is some rust on them and i'm not liking it. Anyone know where I can get calipers? Maybe even powder-coated?

 

If its just surface rust your not liking, why not get them electroplated, I use a nice gold colour on the brakes I restore for XK's (original 1950's flavour) E-Types and Mark II's, they look really smart - I'd avoid powercoating calipers as they have a hard life and plating looks better. You can have a choice of silver or gold or gold/green depending on what types of plating your man can offer.
Or, you could paint with a heatproof enamel paint, after wire brushing the rust off.
I think it's a bit extreme buying new when they're just rusty.

Great Idea! I'll look into it this week.

What about rotors? I would like some cross-drilled/slotted ones. Do you if the 2001 rotors sizes on the XJR would fit on my 2003?
