Re my post above.
Yip, I`ve fallen in the trap I didn`t know was there until I read the Brembo site link.
I`ve fitted the grooved discs on the back brakes back to front. They are not therefore so efficient.
I`ll have to jack the car up again, remove the callipers and brackets again and swap the discs from one side of the car to the other.
A lesson learned.
Embarrased- well yes!

Re: Retrofitted Brembo's and wishbone bushes/joints
Hi Nic/Mike,
I've always believed that grooved discs aided water dispersion and drilled discs were designed primarily to disperse gasses formed at the interface between the pad and disc under hard use. Presumably Brembo consider that 'you pays yer money and takes yer choice' as to which problem you're trying to solve. Drilled Jaguar Brembo discs are definitely directional and have a groove around the outer circumference of the wall of of the left hand disc for identification purposes. Hence, it makes sense to fit them the correct way round if the cooling vents are to operate properly. Mike.
