well its not going to be that much heavier, but if the OEM springs cant even handle the weight of the factory set-up then they gotta go is all I'm sayIng..I'm really trying to keep thisas affordable as possible...plusit's kind of fun to see how much bang I can get out of this for as little cash as possibleand still have a battle ready, reasonably stout tank lol...or at least that's the theory...Personally if I decided to spend all the money going Asiatam I'd jsutas soon go ahead and buy a Tamiya...just my personal opinion. But I'm a "budget" tanker and like to show that I can have a cool tank to and not have to dump 2G's to do it....
