Just to be clear about the hubs that go on these cars.

This hub design came on the following cars and it uses a wheel center cap that bolts to the wheel (see pics). The rear assembly is 2.4Kg with the nut being 115g of that. The steel wheel center cap weighs 325g
996 RSR
996 Cup
997 Cup




This is what came on the 997 RSR and the nut locks down to a tapered hole in the wheel instead of a wheel center cap. The rear assembly is 2.4Kg with the nut being 165g of that. The wheel is likely heavier since the center has more material to support the tapered hole and compression of the nut.





If your wheel doesn't work with this hollow spindle and large nut, it isn't a 997 RSR wheel and if you have the 996 type hub, you can't use a 997 RSR wheel.

I still like to know what inner and outer rims à 997 RSR use

Mark, Any finished pictures of the E88's? Thx

mathisengineering

Pictures are coming. I've machined some for a 5 lug hub race car. I have wheel paint coming from BBS in Germany that should be here Mon or Tues. When I paint them, I'll post pictures.

The orignal listing of the 3 piece wheels said they were aluminum. That was wrong, they are magnesium.

Mark, the electric power steering pump arrived fast, well packed, ready to install - Thanks!

Here are wheels I've been building up in this past week. I've had a lot of requests for odd offsets for BMW and other cars. I can machine in Porsche and other car make hole patterns as necessary.



Here are finished center lock mag 996 RSR wheels ready to ship out. These have new gaskets, bolts and paint.





Here are a pair with the 5 hole pattern machined into the centers.

They look gorgeous

Looks great Mark. So no e88 centers in aluminum?

I was wondering if it's possible to buy inner and outer rimhalves from you separately?

I'm looking for 8" inners and possibly also some outer rimhalves. I have 7" and 7,5" inners to trade with or I will purchase outright.

Wheels look beautiful. Let me know and have a nice weekend!

mathisengineering

I PM'd you.

Mark,
They look great. will they fit a 993? also I see these are very deep, which is a nice look.

mathisengineering

I would need to know width and offset of the wheels you would need.

Alternatively you can give me your stock widths and offsets and then tell me how much farther inside and outside you want the wheels to be. I can figure out the rest.

Any more electric power steering pumps left?

Sorry but I sold all the RSR steering pumps the first day I posted the thread.

I can get new RSR electric power steering pumps from Weissach to sell you for $1200+shipping to you. If interested, e-mail me directly.

I have several pair of large Alcon 6 piston calipers for sale. They cost $10,000 per pair new. I'm selling a pair for $2,500. I'm also selling the 15" steel rotors and the floating rotor hardware that these work with.

The best cars in the ALMS series and LeMans run these. The BBS deep RSR wheel centers are designed to clear these brakes. I still have several of the centers I can sell for $400 each.

Also, I'm getting more used RSR electric power steering pumps from our storage in Europe. These will be $750 each. I can sell new ones for $1200.
