I have an '06 STR; are the front rotors supposed to be cross drilled or just plain? What is the OEM spec and part #s for these?
do chinese import parts fint their way onto these cars?
thanks all for the informative forum!

 

OEM plain.

Are yours the non-Brembo? Sizes vary, depending...

 

Non-Brembo for a USA 2006 STR.

First year Jaguar dropped back to the single piston floating caliper from the 4 piston fixed caliper Brembo's

Funny thing is the rear are cross drilled! The calipers are red with the letters IR. I suppose they could be uprated some more. Does seem to stop on a dime and give 9cents change tho!

 

OEM weren't cross drilled on any S-Type, front or rear, so someone's messed

Your rears are probably ventilated whereas the Brembos are solid rear.
