the squat is from the stock springs...they are just soft....replace em w/ some integy or trinity springs.....as far as the best aluminum...ACNC is good for the money but heavy...UE is light and strong but breaks the bank....integy is cheap and made to break instead of tearing up your other parts.....Fastlane, AtomicRC make good stuff too......this all comes down to what your wallet can handle...a full UE rig can run about $3k......but it will be absolutely hardcore ass stomping truck.....there's other companies but I preffer tonot give them any help selling there stuff, (search and ye shall find)....RPM is best A-arms/ skidplates/ steering knuckles & braces...the towers are a lil soft but they won't break (just let your shocks flex around).....BTW if anyone is looking for a tranny and a 1/10 scale bulkless setup for the maxx I have em in excellent condition for sale...hint hint.....integy chassis and MSR4 piggybacks too......
