I have a few questions and maybe someone can explain these for me.

1: I am looking into buying some CRC tires, mainly because I like the dish rim, and they are quite cheap. I wass wondering if anyone could help me with comparisons for tires. I am running parma magenta fronts and jaco pink rears, and was wondering if someone could help me with the conversion to CRC tires. Also, do CRC front rims use flanged or unflanged bearings?

2: I am looking to buy most of the bodies on the roar aproval list, just to see how each handles and where it is best used. I never really understood the concept of downforce, and my question is, do open cockpit bodies offer more or less downforce? Running on carpet, wouldnt I look for a body with less over all downforce? Lastly, concerning the trinity T-310 body. Will it fit on other chassis(specificaly an L4) or was it designed to fit on just the reflex?

Thanks
