i got my order today (technically yesterday; it is 1:00am here right now)
HOLY SHIT!! the hotbodies tires i ordered are huge! they inspired me to put the extended chassis plates back on my flux. they are the perfect size for a xl length savage. they are very heavy though. i dropped from 22/47 to 18/47. hopefully that is enough to compensate for both the extra size and weight.

They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
