The drivetrain parts would be front and rear differentials, dogbones, and wheel shafts.

In my opinion, other than the knuckles those are the only essential aluminum parts to get. My car had complete alloy and I just found it to be way too heavy and the gearboxes never seemed to fit properly.

You can get the shock towers and shocks but I think it is more for dress up, because the alloy parts do look nice.

Hope this helps,

ok guys that helps a lot and i haven't ordered form atomic yet but I would have do thanks:) And what are drive train parts?

Well, one thing that you should know, is that you shouldn't buy aluminum parts from AtomicMods, if that's what you did.

They just buy the parts from a company in Hong Kong called GPM Racing.

Without ".hk" it is a different company.

Essential parts:
~drivetrain parts
~axle cups (removes whatever wheel wobble is left over with plastic parts)
~knuckles (these will break on you, first)

Those are the parts you'll get first, but I'd also recommend the shock towers, because those being aluminum, would help durability. :wink:

I hope I helped.

Knuckles, and the delrin gears are worth it too.
