Whiteline 86-89 Mazda RX7 Series 4 / 05/89-91 RX7 Series 5 Front Caster Adj Kit - Control Arm

If you're looking to get a better feel for your 1986-1991 Mazda RX-7's front end, this caster adjustment kit from Whiteline is a solid option. It's designed to help optimize your front wheel alignment, specifically by increasing static caster. This change helps maximize the tire's contact patch when the car is cornering, which can lead to sharper turn-in response and better stability when you're driving in a straight line.

The kit uses bushings made from a synthetic elastomer, which Whiteline has formulated to resist common shop fluids like oil and grease, as well as ozone and general weathering. This means they should hold up well over time. The alloy components are anodized, giving them a protective layer against corrosion and wear, and they look good too. Whiteline also includes internal grease reservoirs in the bushings for self-lubrication, and they supply a special grease with the kit to help extend their life.

You'll find an installation guide included, which walks you through the process of putting these parts on your RX-7. Getting the alignment dialed in can make a noticeable difference in how the car handles, especially during spirited driving.
