You should not upgrade every thing to aluminum While aluminum parts look great, replacing plastic components (like suspension arms or shock towers) with aluminum on a basher is a "noob trap" that often makes the car worse. Here is why you should avoid this, along with other, more effective strategies for beginners. Why to Avoid "All Aluminum" First - Transfers Impact Force: Plastic is designed to flex, dampen energy, and break cheaply, protecting expensive parts. Aluminum does not bend; it transfers the impact energy to the next weakest point, which is usually the chassis, bulkhead, or transmission case—a much more expensive repair. - Added Weight: Metal parts make the car heavier, increasing inertia and leading to harder impacts, which causes more damage over time. - Deformation: Aluminum bends rather than snaps, and it is very hard to bend it back to its original shape, forcing you to buy new parts anyway.
