Fronts only. Rears are same as mk1 lcr.
You can run them with 345mm discs with custom brackets. Same brackets I have on the vRS. Clearace isnt great with that setup. 3mm spacers on a pro race 1.2.
Or use the 362mm kit which fits with no spacer and 5mm clearance on a pro race 1.2.
Advantage over porka brakes is there are more disc choices other than the 350mm merc disc. Otherwise they both work well.
Meant to be better with a master cylinder upgrade. Im fitting my new kit without the ms upgrade first, then the ms upgrade will be fitted so I can give a decent opinion on it. My kit has the same piston size as the db9.
