In case anyone doesn't know, T.O.P. has re-designed the R12 front lower suspension arm to allow the use of smaller tires. They made it a lot lower and you should be able to run the tires right down to the plastic. The new arms are the same part number and supercede the old ones, they say "Ver. 2" on the header card. All the kits packaged from now on will have the V2 arms, although there are probably a lot of old stock kits still out there. All kits sold by TOP USA will have the new arms, and any TOP USA Dealer can get a free set of arms for every kit already sold
