SPRINGS Springs
High performance coil springs are suitable for most street and/or stock chassis racing classes. They replace the stock units with no modifications. All the springs listed lower the car some and give improved handling characteristics. The three brands we offer are supplied by Racing Beat (RB), Suspension Techniques (ST), and Eibach (EB). They differ in their designs somewhat, so we have chosen to carry all three and thereby offer a wider choice to our customers.

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.

FRONT
Manufacturer Rate
Stock 95
Racing Beat 130
Suspension Techniques 120
Eibach 70/185
 
REAR
Manufacturer Rate
Stock 90
Racing Beat 80

Eibach (non-Turbo) 85/165
Eibach (Turbo) 90/165

 

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 at MAZDATRIX chose to carry both and thereby give our customers a wider choice. All bars are supplied with Polyurethane Bushings.
