What is caster adjustment and why is it important?

Caster is an alignment angle that affects steering stability and cornering. Adjusting caster can improve your GTO's steering feel, making it feel more centered and stable at speed, and can also influence how the car behaves when you turn.

What is the benefit of using polyurethane bushings over stock rubber ones?

Polyurethane bushings are generally firmer than stock rubber bushings. This firmness reduces unwanted flex and movement in the suspension, leading to a more direct and responsive steering feel and improved handling characteristics.

Does this kit come with all the necessary hardware for installation?

This kit includes the urethane bushings for caster adjustment. It is recommended to consult the manufacturer's installation instructions for a complete list of required hardware and tools, as some original hardware may need to be reused or replaced.

Product Details

If you're looking to dial in the steering feel and alignment on your 2004-2006 Pontiac GTO, this urethane caster bushing kit from Pedders is a solid option. Worn suspension bushings can lead to unpredictable handling and a less safe driving experience, affecting everything from steering response to tire grip and brake performance. This kit replaces the stock bushings with durable polyurethane, designed to allow controlled movement within the suspension while keeping your mounting points correctly aligned.

Pedders uses a specific polyurethane compound that balances the need for durability and performance with maintaining a comfortable ride. This kit specifically targets the caster adjustment, offering a range from -0.5 to +1.25 degrees. Getting your caster set correctly can make a notable difference in how your GTO steers, especially during cornering and at higher speeds, giving you a more connected feel to the road.
