I would not go aluminum because it adds weight and once it bends there's no turning back. I would recommend using rpm components because their lighter and guaranteed for life.
Depends on the part....some parts you want aluminum some you dont but I do agree that if RPM makes a replacement part I would buy it over the aluminum ones.
Sorry i didnt see that you said "chassis" upgrades. I was thinking more in terms of a-arms, bumpers etc when I said RPM parts. What chassis upgrades are you thinking about doing?
No.. Lonely to know because I'm starting in the world of car racing and I just bought a BULLET MT 3.0 that is about reach me, and I'm reading a lot about all this to be learning, I want to take and ask you some manual where it can follow the steps for carburizing and Start using this car?, I have to take into account? thank you very much
Typically for alloy, if it sticks out, leave it as plastic as alloy will just bend get tweaked anyway. I use alloy in places where I need strength. Axle carriers, servo guards, diff cases, center spur holders, chassis braces, stuff like that. Arms and towers I leave plastic, turnbuckles I change to titanium if I'm breaking them.
