Never will you find a car with both unless someone has been silly enough to do a bit of DIY wrong.

If your doing the disc conversion just smash it on, they're all the same.

HOWEVER, as most find you will probably experience aswell, putting discs on the back makes the pedal very poor, being as you have a 22mm master cylinder.

There are a couple of people ive spoken to who claim to run a 22mm item and have a good pedal and i have no reason not to believe them, but the majority of people have the same problem as me and i currently have a 23mm.......so just don't overlook this
