i see you mentioned after market option availability!
you don't really need any aftermarket options with the XRAY, not now they have released the front chassis brace, maybe the only thing you need to go with that is the King Headz top plate!
other than that the car is good

in fact both cars are good, i own both but at the moment its the XB8 that gets the track time but only because its newer & i'm still trying to get it to work 100% well for me
