Progress Technology Sport Springs!
Now that the Progress Technology Springs are available and will begin shipping shortly wanted to get an overall impression and discussion going for them.
These Sport Springs are going to be one of the best out on the market and I am very excited to have brought this to the community it was a no brainer to have Progress Technology Design them with the Great Success of their Sway bars their springs I am sure of will be a huge Hit!
Progress technology's 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 their 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, Bilstein, or Koni.
Progress specifies only certified high-tensile SAE spring wire materials. Their springs are cold-wound on modern CNC coiling machines, then stress relieved, pre-set, and shot-peened for maximum durability.
Specs of the Street Spring:
Front: 205 Lbs./In
Rear: 145 Lbs./In
Front Drop: -1.2 inches
Rear Drop: -0.8 inches
We will always have these in stock and at the guaranteed best prices as well and you can always PM for the best prices and Combo Specials to grab their excellent sway bars as well.
These Street Springs coupled with their sway bars will be an excellent combination.

Progress Technology wants to know what you think of the new springs!
