Nerd’s Eye View: LA Auto Show 2014: Part 2 – Race Cars and Engines


The front spindle is one beefy looking piece of machined goodness. The vertical rod mounted just inboard goes to the anti-roll bar. The mounting bracket for the front strut has some material machined away to reduce weight but it’s a beefy chunk of metal itself.
The rear strut looks to be large diameter and strong. It appears the remote reservoir body is finned to increase heat transfer and reduce the temperature of the shock fluid. Just to the left of the strut is the anti-roll bar.
When I saw the brake rotor, the first thing I thought was, “I’m not fat, I’m big boned. Beefcake!” The picture does not do the rotor justice, that thing is thick! The reason it needs to be thick is due to the nature of rally cross; the cars spend little time at very high speeds and therefore do not get much cooling air for the brakes. What the cars spend much of their time doing is accelerating very hard and then braking very hard putting a ton of heat into the rotor. So a thick rotor with some thermal mass and strength is required to survive the punishment that GRC drivers and courses subject them to.
There’s not a ton going on in the cockpit; the dash looks downright empty. A single display screen is mounted on the steering column and a small control panel is mounted at the base of the shifter and turning brake. Check out the load cell on the shifter which tells the computers when a shift is being demanded so as to control fuel and spark for full throttle upshifts and rev matched downshifts.
Check it, the steering column is adjustable height.
