Barry White: The rear chassis brace looks like a scaled down version of the brace Hpi used to make for the 10L, I'm not sure if they ever made it for the 12L or not. It might be a one-off for Hara's car. It also looks similar to a Trinity rear brace.
As for the front-end parts, Blackstock, Dumas, Delano, Baker, Orr and Lufaso all use the white front-end components for the Dynamic strut front-ends. At least they do at Cleveland, the Nationals and everyother Triple Crown race. I know a few of them occasionally dye the parts, but they still use the old Nylon parts rather than the new fiber impregnated pieces.
