Rodent Racing - The Build (Handling)

Town mouse has decided to use an RX8 for this. A rotary powered, rodent driven, rear-wheel drive car. Belittled, underpowered and always the underdog. Looks nice though. But first, we need to put a few things in.

For handling, Autoexe undercarriage braces and sway bars. http://www.autoexe.co.jp/ Sway bars connect opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction. The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width. The other function of anti-roll bars is to tune the handling balance of a car.


The undercarriage brace provides a rigid framework under the car to eliminate chassis flex, ensuring correct suspension geometry at all time. It bolts directly to the sub frame to further stiffen the uni-body. The under brace prevents flexing and twisting of the chassis by connecting specific points of the undercarriage to reinforce the chassis. Your car will feel more stable and solid, turn in more accurately and corner more quickly.














Target: Finishing the 12 hours MME in 2011
