Thanx for the responses. Was planning to start the build on the M06 soon and was putting together a list of parts needed. Seems like the only useful upgrades are a set of TRF shocks and some little stuff like a good servo saver and maybe a R1Wurks end bell fan. May buy the aluminum front uprights cause I like sturdy. Also will start out with the dog bones cause the rears of my cars are usually pristine, but the fronts take a beating. I don't mind spending $$$, don't want to spend it just to spend it.
So far the bucks will be spent on a hi end servo, KO esc and a KO reciever. That way, if the car isn't to my liking this stuff will go into a different car.
