Hi I have a 2007 XK and was thinking of updating my brake calipers. There’s a set of Brembo brakes from a S Type R 2003. The bolt spacing on the front caliper mounts is 5-7/8" inches center to center. The rear caliper bolt spacing is 3-1/2" inches. Dose anyone know if they’re compatible? Any insight would be appreciated.

 

I just went through a a few months of finding brakes for the my '13 XKR and talked to Brembo, Alcon, AP and no one makes the correct brackets and calipers that fit other then Alcon. Alcon made a 6 piston front and 4 piston rear optional for the the portfolio edition.

Now comes the fun part they are out of stock worldwide as I spent the past month with SNG Barrett finding the right parts. They did a fantastic job finding the parts but it took jag putting out a world wide search for them. If you want a brake upgrade I suggest contacting Tony at SNG as I know he has a right side caliper in stock but will probably have to search for the left.

Finding brakes for this car is NO joke in effort as I found out, but am very happy with the results.

BTW When i spoke with Brembo they were going to try and make a custom kit but decided it wasn't worth the effort, so I doubt those fit properly. Please don't take chances with brakes as it can be obviously very dangerous.
