First off, Yokomo makes three drift tires. Well, four actually, but one has been discontnued.

The R-03's are rubber drift radials, which I would use only with nitro or burshless powered cars since they're pretty damn hard to break loose.

Then we have the Zero-Ones, which are the original double-ringed tires. The rings wear out extremely quick, but they provide a good amount of slip and grip, given proper camber settings.

Lastly, we have the Zero-One R's, which are the newer single-ringed tires that first debuted with the D1 Drift Packages. The rings are made out of a harder plastic than the original Zero-Ones, but they aren't pourous like ABS, so it'll be a little on the hard side to get used to.

I personally run ABS to drift. It provides a great amount of grip and slip, and it's cheap as hell! I think the the eBay ABS tires are a ripoff since a 10 foot tube of 2" ID ABS costs less than half of those "Drift Specialties" tires.

A little off topic, but Juice, what squadron are you in? I'm at FEW also, working at PK, but I'll be PCS'ing back to Cali in about 3 weeks. It's cool to know I'm not the only RC drifter in Cheyenne.
