Hopefully they are doing some sort of watts link suspension in the rear just like the Griggs GR40 system that turns Mustangs into one of the best performing cars on the track and its an all in one kit sold in a box. That is going to be the only way to plant 550hp on the un-even surfaces of the ring.

Heck I could build a better ring version with a Griggs all in one box kit, carbon brakes, Shelby/ Revan Rad and heat exchanger, and the Torsen diff from the LS rolling on ZR1 rubber.
