hi fella.
Ive tried both chassis types and tbh a waste of money really.The full alloy one bent under a heavy front impact and the carbon one snapped where the alloy front brace attaches. I wouldnt waste your money tbh.The stock chassis with the carbon upper brace is adequate.You can make a reinforcing plate from this :-

Just lay your chassis plate on top then drill using a 3mm bit through the end holes on the chassis,then put m3 bolts through it and secure.Then just cut around it and drill through any holes with a 3mm drill bit.Flip over and counter sink required holes.You can sort the front kick up by scoring the line across where the front of the chassis kicks up,then carefully cut 1/2 way through the sheet to allow it to bend up.You then reassemble the chassis,with this carbon plate on the bottom,it will ensure no more snapped chassis plates
Ive just sold mine so have no pics ,sorry.
The banzai chassis wont fit a carnage,its to short
Fitting alloy arms isnt also advisable.I broke one and bent the other, and ripped the side off the gearbox as the alloy has no give or flex.You are best of using alloy pin mounts,rear bearing carriers,front knuckles and steering arms for strength,but use stock plastic arms as these will flex or in worse case snap,reducing the risk of damaged chassis and gearbox etc.
hope this makes sense .
