Progress Sport Spring Evo X MR
The car is so dirty and I will take another proper pictures tomorrow. My driveway is so steep and it only leaves me 2cm before scraping it.
Progress vs Stock
updated...still dirty.

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
-Front drop: 1.2" --- Rear drop: 0.8"
-Front rate: 260 lbs/in --- Rear rate 230 lbs/in
-Limited lifetime warranty!
-All spring kits are powdercoated metallic gray.

The car looks much better and no rubbing problem. Much better dive resistance on hard braking. Great handling responsiveness, and I didn't noticed any degradation in the ride. Car lost vitually most of the dip/dive it had on stock set up. Ride quality is stiffer/firm response to a bump than stock but not unbearable. Less bodyroll, easy to do lane changes.The car feels lighter. The dropped is not so extreme just right for my angled driveway. No cluncking noise on small bumps moderate or slow speed. Extremely pleased with this product for street/daily driving.
