Since the stock electric power steering does not have enough oomph and fades in hard use, a Camry steering rack was used because it had the same mounting bolt span as the stock FR-S rack. To reduce bump steer and to increase rack travel, outer tie rod spacers were made to allow more rack movement and provide a solid steering stop to prevent rack overtravel. The spacers put the outer tie rod joints in line with the lower control arm pivot. Solid rack bushings were machined to get rid of excess slop.
The rear brakes use lightweight Wilwood Sprint Car rotors and hats with Dynapro calipers, one for the regular brakes and one used as a turning brake.
The front brake use a 14″ Sprint Car solid super light rotor and alloy hat. The front caliper is a six piston Dynapro. Drift cars need a lot of braking power but don't have to do repeated stops from high speed, since there is plenty of time for the brakes to cool between runs. Because of these interesting requirements, light, solid unvented rotors and high Mu pads can be used.
The turning brake is activated by this driver operated lever with the blue knob and master cylinder. A Long shifter operates the G-Force GSR transmission.
A Wilwood top hung pedal box, dual master cylinder and balance bar assembly are used. The firewall is reinforced and boxed in where the pedal box is mounted to maintain good pedal feel. SPD prefers top hung pedals due to easier accessibility and the ease of getting a good solid bleed from the system.
A look at the pedal system from the inside of the car. The brake bias is adjusted via the balance bar that goes between the front and rear master cylinders on top of the pedal arm.
