RWD rear progressive springs medium hard

RD-010RMH - Progressive rear springs medium hard - REVE D
It is a double progression rear spring, specialized for surfaces with relatively low grip such as tiles and painted concrete!

We have conducted extensive research to select the material, the steel quenching temperature, and the quenching time with many results to compare. We offer a range of three types of rear springs (Medium, Medium Hard, Hard) that can be selected based on the vehicle's weight and road grip.
With the 2-way structure, the springs can be tilted up and down to instantly adapt to the track conditions. (Please refer to the following explanation for more details)

Main specifications of the medium hard spring:

Length: 32 mm
Number of turns: 10
Shrink tube color ID: yellow

Matching rear PC table:

Introduction of the 2-way structure:

Coil on top:



By raising the spring's center of gravity, suspension statics is induced and the kick sensation is stronger.











Coils at the bottom

By lowering the spring's center of gravity, excessive suspension movement is eliminated and stability is increased on low grip

Shrink tube for identification:

A heat-shrinkable tube is integrated for easy identification of the springs.
(* Medium: Black, Medium hard: Yellow, Hard: Red)
Cut it to the desired length, attach it to the spring referring to the picture, warm it with a dryer to fix it (※ Be careful of burns when using a high heat dryer)









The 0mm cups are recommended:

For PC rear springs with a spring length of 32 mm, we recommend the aluminum spring cups (RD-007-0) with a mounting height of 0 mm. It is possible to eliminate the mounting play with the external guide piece and maximize the original performance of the spring. https://www.driftparadiz.fr/produits/coupelles-amortisseurs-0mm-reve-d/
