Zimmermann (who is an OEM for Porsche rotors) offer these 322 mm floating front rotors for 993 Turbo/RS in their "Formula Z" aftermarket tuning program.
They float on spokes similar to what is seen on Audi R8 and BMW M cars. I can't find a USA vendor. Anyone know where to buy?
They cost 204 Euros in Germany which includes 19% tax = about $285 and are supposed to last a lot longer than stock non-floating Porsche rotors of same size.

I hope this set of rotors are better than the previous versions I've purchased approximately 4/5 years ago. Until I changed to OEMs, I've always had vibration issues with Zimmermanns' disks.![ducking](https://rennlist.com/forums/graemlins/icon107.gif)

There is a difference between 'OE' and 'OEM'.
Our cars came equipped with Brembo rotors. That is OE, or original equipment.
Zimmermann (and possibly others), are considered OEM - original equipment manufactures. They make parts & items for companies such as Porsche, but are not necessarily used during the manufacturing of the car.
When you purchase new 993 rotors from Porsche, you'll receive Brembo rotors.
Hope that helps.

They also make a "coated" line that is rust resistant, see links:
