You'll notice, the lack of the turntable differential. What we have here is a heavily modified previous generation diferential, with 4 double bevel 12 tooth gear halves. The normal thin 12 tooth gears just don't hold, they break and the teeth get destroyed almost instantly. We'll see how this holds up.
The suspension is multilink, and has precisely the same setup as the original challenger rear suspension. When the suspension gets compressed the rear toe arm causes the wheels to gain a slight toe in.
