These brake rotors are original SP developed items (or M1020 prototypes cars from 1994, which were then farmed off to the production SP Australia cars). * years later they were brought back out for the Type R, Bathurst and also the Spirit R and Type RZ RX7's.
The SP has a different front brake caliper to standard and reworked ABS to match the braking system size.
The brake rotors are simply the stock sized units but vastly better than the std Mazda offering, I run Project Mu rotors front and rear with Project Mu pads. The car makes so much horse power and velocity that I broke a rear disk rotor last time I had it out on a race track! they just cannot handle repeated high velocity stops at full braking power. Sure if it was like the stock SP with only ~350bhp in race trim it could do it for 12 hours straight like they did in competition, but with now 600+bhp not a chance
