I dunno. I doubt that one car is specifically 'faster' from one another. Its totally driver dependent. you may have a bad-a$$ all CF 1000-way adjustable car, but if you do'nt know how to mess with the camber, toe, yatta, yatta, then.. money says it'll probably end up slower. I kinda speak from experience. there a lot of factors in buying a R/C car. Cost, parts availability where you're at, driving style. I remember the TA03, (no offense to Tamiya or anything) and a while back my friend got it 'cuz it was the 'hot setup'. Well, with the engine in front and all, he didnt' like the way it pushed. A lotta mods later, (including moving the engine to the rear), he was finally content. Kinda opposite of myself. I bought the Yr-4M. It was awesome and all, but that damn one-way diff. My driving style wasn't smooth enough like Masaki to handle it. I was always spinning out and got hella frustrated. (I later sold it and got a Yr-4GP and became a very pleased customeR). Just shop around, talk to different people at the tracks and shops and see what you like. If you're in So.Cal, nothing beats Ultimate Hobbies in Orange. Later.
