Anti-Sway Bars
Larger diameter Anti-Sway Bars reduce body roll in turns, giving a much firmer feeling car and better cornering ability. The two brands we offer are supplied by Racing Beat (RB) and Suspension Techniques (ST). They sometimes differ in their design, so we chose to carry both and thereby give our customers a wider choice. All bars are supplied with Polyurethane Bushings.

In order to help answer many of our customers questions, and to satisfy our own curiosity, we compiled the following chart of spring rates. The numbers are from our own spring tester and should be used to show relative differences - not necessarily for the absolute rate number. The dual numbers are for progressive rate springs. This design type uses a lower rate for normal ride, then progresses to the stiffer rate when compressed while cornering.
