I decided to give these discs a try. bought a pair trough the Swedish dealer. Let's see how they hold up next summer. The comparison may not be fair as I am converting the car to GT2 EVO so there will be a LOT more cool air to the brakes then before.

Guys to answer all the requests for rears I may have a pending solution.
I am fitting slotted rotors to the front, but these rotors use the stock steel hats. A very economical solution. Since I like things to be matched up I am going to do some steel hats for the rear that take the same rotors. They will be in 4140 steel and have the park brake drum. Weight will be the same as the stock disc. I have a program right now that is doing some metal spraying on aluminum and I have thought to do some aluminum hats with the drum brake surface metal sprayed. But the cost, and complexity don't align with the minimal weight savings. I also have guys bring aluminum hats over to be trued after a couple of discs have run on them, steel won't have those issues. Unless you are going for the max, aluminum hats offer little advantage over steel.
I do want to get a set done and on the car before I produce sets for anyone else. These rotors like the Giro Disc have a turned friction surface and I am not a fan of that. For me a unidirectional grind (like production rotors) is a far better friction surface for initial bedding. I will supply the new rotor with ground surface and balance the assembly. Will also know what the rear assembly will be worth once I finish the first set. If timing works as planned the rears should be complete in two to three weeks.

Craig, sorry you feel that my post was tacky. Also I did not know it was a vendor post so I will move any further submissions to their own post. Along with yourself, many made comments that it would be great to see a rear solution. As I have done previously when I make parts for myself I offer them up to other members and do it for net cost. Design, engineering and programming is already done on my set, goes easy after that. That is the intent with the post, it is not to take sales away from a Reseller but to help 993 turbo owners resolve the same issues as I have. If you got twisted over the comment on surface finish you will just have to accept it as an opinion, one based on 35 years manufacturing parts for race and production suspensions. Also not everyone needs or wants a floater, they are happy with stock setups, just need to reduce the cracking of the cross drilled rotors. If one of your suppliers come up with a rear solution I am more than happy to keep my set to myself and let you have all the sales. My intent is to support the community not affect your sales of something you do not offer.
