I have the larger Jaguar STR Big Brakes with the 355mm rotor.The title of this thread seems a bit misleading... so to clarify...
Do you have the S-Type Sport 320mm front rotors and caliper brackets? They use the same pads as the LS... which Akebonos work well with.
Or do you have the even larger STR calipers, brackets, and pads?
Can't be both.
