what do you mean. It comes with full ball bearings. The main differences between the rtr and pro are:
Pro 7075 machined and hard anodized chassis... RTR 6061 aluminum blue anodized chassis
Pro Universals all the way around... RTR Uni's in the front only
Pro Carbon fiber radio tray, center diff piece, front chassis (where torque rods connect, and where the bellcrank connects)... RTR has all 6061 aluminum in those places.
Pro 4 disc brakes... RTR 2 disc brakes
Pro 7075 machined and hard anodized shock towers... RTR 6061 Blue anodized shock towers
If you look at these upgrades, the only things that are really performance oriented (putting power to the ground) are the uni's. Uni's help a whole lot, but if you put a rtr next to a pro w/ all the same electronics, and engine, they will perform the same. Any one dissagree?
Also if you look at the November 2001 RCCA (Storm RTR), and the April 2002 RCCA (Pro) you will notice that the total, as tested weight on the RTR is 3,195g , and the pro is 3,217g. It's a very very minor difference, but the RTR did weigh less.
Don't get me wrong... i would kill for a storm pro, i'm just sayin, that you shouldn't dog my storm by sayin that i got a lot of hoppin up to do, when all the things that you are thinking of are pretty much eye candy.
