nope, they wont fit.
Cup racers have a choice of pads they can use.I think four pots etc are overkill. My standard brakes have enough power to lock the wheels from most speeds - It's more about improving feel and resistance to fade. I've driven a saxo with four pots and the brakes were like an on-off switch lol.
If you doing serious track work get some Brembo HC discs and pagid blues or similar. I think that's the set up the Cup racers use.
