Aftermarket rear brake discs
 

Which brand makes larger than oem rear disc that would allow me to retain the stock calipers? Looking for larger than oem grooved/drilled or both for the rear.

Before anyone says I don't need it for braking power blah-blah, I'm doing it mainly for the bling factor as I've already ordered the 8 pot BBK for the fronts so looking to match up the rears with just a bigger disc for now as the oems are buggered and needs replacing asap. I will budget for the rear BBK at a later stage..

J's do a larger rear disc and caliper spacer kit.

Compbrake have a std size rear 2 piece.
Just get them to fit a bigger rotor, and they will machine the blocks if you spec the sizes.
