Options for Rear Rotors Slotted

[Cyclops]

Anyone know of a stock rear rotor replacement that is only slotted. I just got some rear Porsche Brembo 996 calipers but need to replace my rear rotors as they are gone. I would like to match the front slotted Stoptechs. I've searched but am only coming up with the OEM cross drilled.

I see that ECS Tuning has some for the e46 m3 but they don't list the csl/zcp. I called ECS but they said the hat could be different. Anyone know if the hat or ebrake drum is different on the standard m3 vs csl/zcp? Rotor size seems to be the same 328x20.

I've used Adams rotor to offer matching rear rotors when I was selling BBKs for a company I used to work for. They offer them in many combos for many cars.

There's no difference in rotor size/hat in the rear between the ZCP and non-ZCP cars.

This is the ETK data for European spec E46 M3. There's no distinction between ZCP and non-ZCP cars. In Europe the floating 2 piece slotted rotors are standard, =the ZCP has the larger front rotor.

Also, my memory is a little hazy, but I am 90% certain we took my rear rotors and installed it on my co-worker's '05 non-ZCP E46 M3 and it's a direct bolt on.

P.S.: I know for sure that the E46 M3 guys buy ZCP rotors and bolt them on (the fronts require a new caliper carrier).

Thanks for the tips. I ordered the ECS Tuning Slotted rotors, put them on this weekend and they were a perfect fit, no issues at all. Also added a set of Porsche 996 rear calipers, Rallyroad rear brackets and stainless steal lines.
