Does anyone know of a sourse for 1991 964 Turbo front rotors that are slotted, not with holes. Im having some bad luck with the holes cracking badly after only a few weekends racing at the track. dont know if i want to go solid rotors, as slotted would be ideal.

thanks

brakeperformance.com Admittedly a bit of a cheezy looking site. I have the their slotted rotors, perfect fit and perfect track performance, zero issues. not affiliated. zinc'd slots, hat and internals were a plus.

price was untouchable. lead time was ~ 10 working days, as they cast to order.

Just bought Cryo treated slotted ones from powerstop.com (they are for a NA 964, so I'm not sure that they are the same)

drilled&slotted rotors from brakeperformance here as well been out for 5 DE's with them no issues, using semi metallic pads.

I put the dimple-drilled and slotted on my car. The price was worth the a risk of a newish to the internet company.

The fit and finish is perfect. There is no rust on the hats because of the zinc coating. So far so good, but it has only been a couple months. They also have a lifetime warranty against warping.

There are some bad reviews of the company on the internet, but they are all the same moron.

You can try here.

Or you can call Paul from protosport 973-839-5353 he usually has access to custom rotors and brakes that I have not seen anyone else have access to.

Do you still have a proportioning valve?? I had removed mine on my RSA and it worked fine. Even on the track I found that the front brakes were doing all the work and rears were slacking a little too much. After that all four worked perfectly and never had a rear lock up, which I thought was going to happen.
