I'm wanting to convert my ofna lx comp into a truggy..I'm thinking of going with the 30mm extensions with 17mm hex.I'm also looking at the mammoth st wheels and tires because they are 17mm and can be gotten pretty cheap on ebay..I'm wanting to run a stadium truck body but leave the buggy wing mount and wing..would you run the 1/10 stadium body or the 1/8 which one would work better?also any idea's on how to get this thing geared right?and one more quick question i wouldnt mind having 30mm extensions with 14mm hex but cannot find them anyone have any ideas?
