Description:
Our engineering staff has decades of experience in the design and tuning of performance suspension systems, including CART/Indy Cars, IMSA, SCCA, NASA, and SCORE competitors. These spring designs reflect our ability to develop a successful blend of appearance, handling capability, and ride quality. These springs feature increased spring rates for upgraded handling capabilities as well as progressively wound springs for superior ride quality.
These springs are designed to work with OEM shocks but will benefit from using high performance shocks such as Tokico or Bilstein.
Progress specifies only certified high-tensile SAE spring wire materials. Our springs are cold-wound on modern CNC coiling machines, then stress relieved, pre-set, and shot-peened for maximum durability.
Features
-xB drop: Front: 1.8" --- Rear: 1.5"
-xA drop: Front: 1.3" --- Rear: 1.2"
-Front rate: 165 lbs/in --- Rear rate: 175 lbs/in
-Limited lifetime warranty!
-All spring kits are powdercoated metallic gray.

Q: Can I use my factory struts with lowering springs?
A: Technically you can, but we always advise pairing lowering springs with performance shocks that are made to sit at a lowered ride height since it will improve your ride and handling. The factory shocks/struts can blow prematurely if used beyond their designed suspension travel, and they aren't designed to be used with a lowered vehicle. But technically, yes you still can choose to leave your factory struts there.
Q: How do you install lowering springs?
A: The factory spring and strut housing need to be removed. Once the factory springs and struts are removed, they can be replaced with your aftermarket springs. A professional shop should install your springs, since they are pressurized and since an alignment will need to be done at the same time the installation is completed.
Q: Do lowering springs come in sets of 4?
A: All lowering springs on our website are sold in sets of four; unless otherwise specified.
Q: What are lowering springs? Why buy lowering springs?
A: Springs' basic function is to cushion and absorb the shocks and bumps that are encountered as the vehicle is driven. Coupled with a shock absorber they make up the main element of your vehicle's suspension. When you want to lower your car, you buy new lowering springs that are made to set your car closer to the ground. Anybody who wants to lower his or her car has to replace the factory springs with either lowering springs or coilovers (coilovers are the same as lowering springs, except adjustable).
Q: Are lowering springs adjustable?
A: Lowering springs are not adjustable; you cannot change the ride height on them. See our product descriptions to find out the exact drop the springs offer for each listing. If you want an adjustable lowering system, then you should look at coilovers, which are essentially adjustable lowering springs.
