An ATL Flurocell fuel cell is needed to contain the Ignite Red ethanol fuel. The bladder and foam resist attack from exotic fuel which is super important when running ethanol which can ruin a conventional fuel cell in just a few weeks. A 3″ stainless oval exhaust gives decent ground clearance and sufficient flow for 1000 hp.
The iM rides on custom RSR 2-way adjustable remote reservoir coilovers. The rear suspension uses custom fabricated links and rear uprights for full adjustability and to correct the rear geometry to make it more suitable for RWD within the limits of the rules. The rear uprights allow the car to be lowered without affecting toe steer or not messing up the roll center location.
A Speedway engineering tubular race type rear swaybar is used and is adjustable to fine tune the balance of the car.
The Papadakis iM uses a Supra MK4 rear end with a spool locked differential. Two final drive gear ratios are available for the team to use, a 3.77 or a 4.27 depending on the course.
Many FD teams use a Winters quick-change rear end, but using the MK4 rear end saves about 40 pounds off the back of the car while sacrificing the ability to switch the ratios very quickly.
Here is a closer look of the tubular structure in the back of the car that contains the fuel cell and other auxiliary equipment. There is also a jacking point in the back of the car which is built into the structure which helps enable fast tire changes in pit stops.
The front suspension also offers RS-R 2-way adjustable coilover struts in custom housings. The coilovers attach to the unibody with custom camber plates.
