yea the newest tech. isnt necessary, but as your signature says "it helps" actually if you want to call it new technology, the carpet knife/speedmerchants would be the ones with the new design. however i still prefer the "old" t-plate cars. im running an old rc12lw that i bought from a friend for 60 bux, and i just won 12th spec at the track against carpet knifes...just goes to show ya that it doesnt matter what car you have, you still have to drive it.
