Frequently Asked Questions

Why is a performance chassis harness better than stock wiring?

Performance chassis harnesses (like Painless Performance) are designed for modern electrical loads, offering higher quality wiring, better circuit protection, and dedicated circuits for performance upgrades (EFI, high-output lighting). They also simplify the wiring process in custom or restored vehicles.

What is the primary function of a rust converter on a chassis?

A rust converter chemically reacts with existing rust (iron oxide) and transforms it into a stable, inert, black protective layer (iron tannate or similar compound). This layer then acts as a primer, sealing the metal and preventing further oxidation before a final topcoat is applied.

Are ballast brackets necessary for street cars?

Ballast brackets are primarily used in racing (circle track, drag racing) to strategically add weight to specific areas of the chassis. This fine-tuning is crucial for optimizing handling, traction, and meeting minimum weight requirements. They are generally not necessary for standard street performance vehicles.
