I've been searching around for some time for brake upgrades to go with the 18" Whitleys i have on order since it's brake time as well and I have been trying to find info on what exactly is needed to go to the 325mm XJR rotors but nothing all-in one spot.

So, my question is what do I have to do to go to the larger XJR/325mm rotors from my current stock XJ8 setup?

2000 Jaguar XJ8 soon to have 18x9.5 Coventry Whitleys.

TIA

 

Why stop at 325 - a 10mm upgrade isn't worth the hassle or outlay, you need the 355 Brembo option to make the brakes a focal point, along with drilled rotors they look cool but it's an expensive folly unless you're of a competitive nature

 

Not for this car, not a fan of drilled anyway - my track car get's slotted.

The reason to go 325 is since there is little cost difference I might as well.

 

New calipers, rotors, and pads is all you need, and obviously some new fluid since you're changing calipers. The brake lines work with either caliper. And your XJ8 front brakes are actually only 305mm, and a narrower rotor to boot, which is why it's a worthwhile upgrade to go to the R brakes. It's a very easy upgrade.

 

Cool, are the rears any upgrade?

I already use Ate super blue fluid in all my cars so that's a done deal.

 

All you actually need is the carrier, the caliper itself is exactly the same..

Rears are the same

 

Any chance you know the part numbers for the carrier?
