another flux 2350 XL

hey guys here is my savage flux XL all i can say is pretty much instant wheelies, i'm loving it! the specs are
leopard 4074 2200kv motor
2x 2s 4000mah
150 amp ezrun.
Goliath wheels
XL conversion kit
Wheel extenders
Sway bars

I'm new to the monster truck part of rc's had pretty much everything except a monster truck. so any tips on upgrades would be awesome. i know the first upgrade is to get rid of that ugly rear steer with the integy rear hubs? any good for the money? i Wanted to run the 2200kv 4082 size leopard for extra grunt but i don't think i will fit it in the chassis? any opinions on upgrades etc would be greatly appreciated. here are a couple pics.
thanks
