The belleville is merely serving as a spring. I'm guessing it probably centers itself up pretty well when you run the 8-32 nut down on it anyway.

I ground the carbon from an old Xray front bumper. I have a bench grinder and a set of diamond files that will bash bits of fibre about. I hit this one right first time.

I made a brace last night out of a lower pod that I broke the previous weekend. The holes were in the perfect position and counter sunk and all I had to do was to cut it off and smooth the edges. Very easy.

On the CRC site, if you go to the parts page and search for the part number it should show up. This is what I did to find the little parts that aren't listed yet.

Brace Update 2
Well, I raced the rear brace on Sunday and I think it made the car very stable and very predictable. Even after slapping the boards a few times the car still reacted well. I think Mark is on to something here. Now I need some feedbace from a few other people.
All for now

CRC Tires
Hi all, Is the CRC procut Megents rear between a gray and a pink for shore?
I am finding that gray or white is to hard for our track making the car to loose but pinks seems to be to soft, and pickup to much carpet fuzz, so I was thinking of trying Megenta on the rear. Any thoughts??? I am running purple on the front and I do like the way they make the car feel.

CRC's web page "Foam Tire Mysteries Explained" actually creates more confusion. They don't even show all of their own tires in the charts. In their charts, they use "CRC Designation" like R2, F3, etc.. but I don't see references to those values in their shopping carts. You can actually get more shore rating information out of their shopping cart.
I think white is the softest.
According to their shopping cart:
Magenta rear: 34 - 38 shore
Pink: 30 - 33 shore
According to their Mysteries page:
White - C2: <33 shore
Grey-C3: 33-38 shore
To make it more confusing, their magenta fronts are a different shore than the rears! The fronts are 36 - 40 shore "soft purples".
CRC's "Foam Tire Mysteries Explained" page really needs to be overhauled. CRC are you listening? (probably not, they don't frequent the worlds most active discussion forum very much.) A single chart with these columns would make things much easier to understand:
CRC Designation, shore rating, rubber type, suggested use, Other mfgs designation.

I am glad to see that I am not the only one who was lost when I checked out the chart. I was just looking for something between the Procut white and the procut pink. I thought that the Megenta was the answer.
Thanks for the input.

1) One manufacturers "Pink" (or "White" or "Green") may not be the same as another's.
2) The shore rating does not neccesarily indicate the level of grip a tire has. For example, most White tires are softer than Pinks but have less traction. Everyone assumes shore equals bite and this is not the case.
3) Foam tires vary from batch to batch. This season's Pinks may not work the same as last season's.
It's certainly more complicated than this if you take into account different traction compounds and carpets, old or new. I think you have to experiment with different tires until you find what works for you at your track.
Oh by the way, just because you seldom see anyone from CRC post here doesn't mean they don't read the thread

I'm really not sure why manufacturers don't get off their butts and make some decent charts with at least this info as a minimum:
Our Designation, shore rating, rubber type.
This way, regardless of who makes the tire, you could say, "I'm running American 35 shore", or "Japanese C, 40 shore".
<stepping off of soapbox now>
