Based on my last post recommending the BSR foams, someone sent me a PM and I figure I would answer the same questions here for the benefit of others and perhaps some folks might help me out too:

The mini t or rc18t tires?
And should I get "front/rear" or "2 rear" or "2 front" sets.
I'm guessing they dont work in dirt at all right? I'll have to buy another set for driving in the dirt.
And, do they only come in that yellow color?
I would get the white wheel foams for the 18T, they are compatible with the SC18. I would also get the front/rear set where the front tires have the outer 25% tread with a harder compound to prevent traction rolling. If you still experience traction rolls, then it would be a good idea to spread a thin even coat of CA on the sidewalls of the front tires. I believe the yellow dish wheels only come with the Mini-T option. I am not certain if the Mini-t adapter is the same pin size used for the Associated cars, I have only used the while spoke wheels.
I have had success using acetone to remove the tires which makes it possible to dye the white wheels any color of your preference and then you can remount the tires with some thin CA.
I doubt foams would do well on dirt tracks with rough loose soil, more than likely the foams will be ripped and torn. I have heard of foams being used on well groomed oval tracks with high traction damp clay, though I have not ran these foams on clay to be certain how well they perform under those conditions. I have only used them on a prepped asphalt track in the parking lot near our local HobbyTownUSA stores. If there is a HobbyTown near you, then chances are they stock the BSR's as well.
Best of luck!
