Coke O'Reilly · Richmond.

Richmond rewards a planted right-rear and punishes anyone who chases the front. The trucks load up differently than the Cup car — you have less weight up top and more aero leverage, so the entry bite is more about geometry than spring rate.

We're a click stiffer on the front sway from the Trucks baseline. With the lower COG, the trucks roll less and rebound is what catches them at apex. If you feel the front pushing at apex on lap 3 of a run, take a round of wedge out before reaching for spring.

Race-trim file is the default. Qualifying trim is saved as QUAL. The qualifying file runs less wing — don't try to run that in traffic or you'll be a passenger.
