Updated 7/30/12 - I've sold all the 996 RSR wheels but I still have a lot of the following parts:

996 RSR electric power steering pumps - $750,
Inconel 997 RSR header pairs - $4500,
997 RSR rear wing, deck, upright kits ~ $6,000 depending on year
Driver adjustable ARB system made to order $5,500 (see page 6 of this thread for more pictures)
Complete 997 RSR suspension corners in parts or complete ($6,000 for 4x complete uprights with spindles)
997 RSR 4 way adjustable shocks - $10,000 per car set

I have a ton of 996 and 997 RSR parts for sale that come from a top US team. All of the parts are low time take offs that are kept as spares. We change out the tubs so often, we end up with piles of parts to unload. Let me know what you need and I'll see if we have it to sell.

many thanks mark

I'm working with one of them but I'm not supposed to get into that specifically. The idea is that I'm brokering parts so the team can concentrate on winning races. They have no capacity to retail parts directly. If they get flooded with calls for parts, the flow of parts will stop.

I'm a former full time race Engineer with a relationship with DP, Indy Car, ALMS teams etc. I've helped many of them with design projects and I help them sell parts as a side thing. Because it is a side thing and I have to communicate sparingly with the teams and it sometimes takes a few days to get back to folks. However, the parts are top technology and they are useable low time take off parts that they have because they were kept as spares.

If you buy all 4 corners, I will go $5500 plus shipping. They are $1500 each as singles.

I am currently making bar kits and parts for blade adjustable ARB's and they come with either lockable blades or cable adjustable. The lockable blades simply lock in the sockets and can be changed quickly in the pits by rotating (same as stock RSR but bigger). They are $1500 each for a front or rear. I make them all from 35mm tubing (larger than RSR). I make 5 different bar sets that are stock or 25%, 50%, 75% and 100% stiffer than the factory original bars. I have the front versus rear designs well sorted out. The blades are slightly stronger also. The parts are $500 each (each blade or each bar). The kit for one end of the car comes with 2x lock caps, 2x lock screws, 2x blades and 1 bar.

If you want cable adjustable (1 blade mounted in bearings with an adjuster arm, the other blade is lockable), I can do that for the rear bar for $500 more. It's a different blade design and a lot more work. I can also get used Indy car in car adjusters to sell for ~$200 most of the time. You would have to get the cables and route them yourself.

I have 3 sets of BBS Magnesium GT3 RSR Wheels for sale. These are 10X18ET1.5 front and 11X18ET15 Rears. They are $2200 plus shipping. Very light! They fit 996 Cup and RSR and 997 Cup that use the small center lock nut. I'm making adapter wheel caps to go on 996 CL wheels so they fit on the large nut 997 hubs also. I'll post pictures of the mag wheels later tonight.

I also have a stack of the deep BBS E88 wheel centers that are like the gold one I pictured previously here. Those are $400 each and I'll machine a 5 bolt pattern in them for you if you need that (no cost).

I could use another set of RSR wheels but I think the rears should be 13" (that's what I run). I don't know the offset but I use 3" outers on my rears, do you know the outer measurements on the fronts and rears?

Mike,

My Motorsports parts book shows the 08 997 GT3 Cup car using the small center lock bolt (uses the safety clip). All of my wheels work with that. If you have that, you are running 996 or 997 Cup wheel centers built out as RSR width wheels. The 997 RSR wheels use the large lock nut with hollow spindle like the corners I'm picturing above.

997 RSR wheels are 11"x18ET34 and 13"x18ET12.5 If you want that, my RSR centers would use:
10" Front inner + 1" outer
10" Rear inner + 3" outer

However, you will want to be sure of the offset numbers because your stock cup car came with a much more shallow wheel center and your 3" outer and 10" inner may be giving you a 13" wide wheel that is still inboard 1.5" compared to these wheels. If you have RSR centers, the hub flange mating surface to inside edge of your wheel will be 7.375" front and rear. If you are still awake reading this and it all checks out, I can build you a second set of wheels.

Here are pictures of the one piece mag wheels:

Here are some pictures I took of the 1st bars I made for the RSR cars. I have almost no parts currently so I'm making more. The silver blade is the stock RSR blade and the one next to it is my larger blade. All the 35mm ARB's look the same but the ID is smaller for the stiffer ones. I can get used Indy car adjusters like this one to sell with bars.

Do you know what inner and outer rims. 997 RSR use

mathisengineering

997 RSR wheels are 11"x18ET34 and 13"x18ET12.5 If you want that, my 996 RSR centers would use:
10" Front inner + 1" outer
10" Rear inner + 3" outer

If you are unsure about what will fit your car, I have 996 RSR wheel centers alone for $400 each. That way you can buy centers and measure what works right on your car. They will work with both the small pin center lock and the large nut 997RSR spindles. For the large nut spindle, they need wheel center caps that accomodate the large nut. I have a design for that but I would have to make them. Of course they can also be machined for the Porsche stud pattern.

Hello

I was intressted in what a 997 RSR use, not what works on the 996 RSR centers.. On my car only 997 RSR style centers are intressting.. no old style here..

Falken never used a 996 GT3, and as he has a lot of 996 parts as well, I would guess it would have to be the lizards...

Either way, that is an astonishing parts horde you have there.

mathisengineering

And piling up more and more every day!

If you think that's impressive, I can supply you with an Indy car motor and transmission to put in the back of your Porsche as well! But then it would be a Pindy car and that doesn't sound so good.
