A big carbon fiber duct directs cooling air to the center of the rotor. The rope zip-tied to the upper control arm should be a wheel tether to prevent the wheel from flying off in an accident. If you don’t recall from general motorsports history, a number of fans have been severely injured and killed from wheels coming off cars in accidents and being struck.
The orange brake duct hose directs air to the brake caliper. The fitting used to attach the brake fluid hose to the caliper looks typical of high-pressure hydraulic applications. It should be more robust than the typical banjo bolt joint used on street cars.
JJ Furillo of Ultimate Performance Speed Shop handles all of the suspension work on the cars. He makes the custom dampers and supports the team with tuning for each event. A number of the suspension fasteners are safety wired to prevent loosening.
Check out the size of that sway bar! Burtin Racing transitioned to engines built by ECR this year after having issues last season with another supplier. Considering their performance in the first two races, I’d say the ECR engines are doing the work of providing power and being reliable. These particular engines are the Chevrolet SB2.2 package running a compression ratio of 14.0:1. Gold reflective tape is used to prevent radiant heat transfer into the driver’s compartment.
The Trans Am cars use a massive tube frame chassis with bodywork attached, so I think the big kart analogy still works. The front air jack is located where the engine bay meets the passenger compartment.
