Newbie here, ?'s about what to buy.

[GorillaMaxx360]

chassis braces are not needed with the gmaxx chassis. a good esc is the mamba moster maxx or the quark 125b. a good motor choice would be a feiago 7xl or 8xl. Also would ditch the metal bumpers they are bad for the car if you hit something with metal bumoers the will transfer shock to the rest of the car which is not good and you might break other expensive parts. I would definatly get aluminum bulkheads which would be something like the combo bulks that use stock diffs or the hybrid bulks that use buggy diffs for lots of stregnth. Many people here will tell you to stay away from the novack stuff. Also the body posts (aluminum ones) need to go the first time you go upside down they will bend and it will be harder and harder to get you body on metal body posts are a big no no. as for the rest of the stuff you got it seems to be ok i would try to stay away from the integy stuff. the arms might hold but not as strong as others the skids are fine for your use. though you wont need a center skid with the gmaxx chassis. the shock towers are fine but again not the best you can get but fine. the shocks, many people run here and i have a set of msr5 shocks the reason they and i have them is for looks they work better than stock yes but no where near next to the performance of others. I actually have some of these shocks and they have never been used and i immediatly bought a set of traxxas bigbores and i will have these brand new unused shocks laying around because the bigbores are just much better. Now that i told you what you could do let me highly complimet you on the gmaxx purchase that is one if not the best chassis you can buy for a maxx it is one of many parts that performs better than it looks and yes this is possible. all in all you are on the right track. and all of the stuff you have you can use exept for sure the chassis braces and the center skid plate (are not compatable with gmaxx chassis comes with that stuff in a sense) but i highly recommend not to use aluminum body posts and bumpers. BTW welcome to the forums (sorry for the longness) Hopefully others will chime in for additional info to help you
