Frequently Asked Questions

Are budget performance parts reliable?

Many budget parts, especially those focused on accessories or basic function (like sound deadening or shift knobs), are highly reliable. For critical engine components (like the LS intake manifold), it's important to check reviews and ensure the material quality and fitment are confirmed by other users, as reliability can vary.

What is the cheapest way to improve my car's handling?

One of the cheapest ways to improve handling is through alignment correction. Products like eccentric camber bolts allow you to dial in better suspension geometry, which is crucial after lowering a car. Upgrading tires is also a highly effective, though slightly more expensive, option.

How much sound deadening material do I need for a full car install?

For a full car installation (floor, doors, trunk, and roof), you typically need between 30 to 50 square feet of material, depending on the size of your vehicle. Products offering 36 sqft or 50 sqft (like the KILMAT or Sound Deading Material) are usually sufficient for most sedans and coupes.
