You don't need to buy new arms for a motor swap with a Sirio .18. However, if you do change over to a widemaxx suspension later down the line, you must replace both upper/lower arms, as well as the turnbuckles. You could even put a Traxxas 2.5 in there, with no mods, and have more power than the TRX 15 or the Megatech......
