Paying special attention to the rear suspension design of the GR chassis, the Functional Lowering Springs provide a mild 5mm drop front and rear to maximize the limited suspension travel available. Shorter bumpstops are included front and rear to take things one step further, resulting in more bump travel than stock. Rarely does an aftermarket spring set-up add suspension travel, but in this case it is a crucial design aspect that improves performance while helping to maintain a civil ride on the street.
Spring rates of 320 lbs/in front and rear are intended to work with the rear suspension of the GR chassis, which has a lower motion ratio in the rear than previous Imprezas. In addition, the OEM dampers have been carefully examined on a shock dyno to match the new spring rates to the dampers.
RCE’s goal was to help cure the crippling understeer that adds to lap times at the track and autocross course. Studying the design of the GR suspension, a new performance spring has been produced that adds to available bump travel, matches the excellent OEM dampers, and works in conjunction with the new rear motion ratio. The result is a car that handles extremely well from corner entry to corner exit.
These springs will not lower the 2011-2012 STI but will increase handling.

Great springs! changed the way my car handled without having the harsh ride of a coilover. Didnt lower my car, which is great considering the bad weather and potholes we have in NY.

I can definitely feel the difference from the stock springs! And the fact that they keep stock height works great for me so the struts won't wear out prematurely. I recommend these to anyone looking for a stiffer ride that's not crazy but still plants the wheels to the ground great.

These springs are well designed. I have them on my 2011 STi with the Bilstein struts. The car is transformed into a precision handling machine.

These are a great improvement over OEM springs. The car feels much more grounded, less body roll, I feel more confident through turns. Not really a noticeable drop in wheel gap but I wasn't going for that! The only thing I don't like about these springs is that they creak over the first few turns and bumps each time I drive and then are fine. I made sure they were seated properly so I'm not sure why they do this!
Q: Specifics - GR and GV applicable raszaron37797 1 year agoAnswer
It states that these were designed for the GR chassis (hatch), and while the suspension design is the same for GV chassis (sedan) of the same years, does the spring rate on these adversely affect the sedan over that of the hatch due to corner weight? I am interested in doing either these or the yellows, but I have the GV (sedan) STI Limited.
A: These springs are designed for both GR/GV. You will not have a problem for either hatch or sedan models. - Larry

Q: differences between yellow and black Dhonn17 2 years agoAnswer
Just want to know the difference between yellow and black spring i have 2009 STI height, stiffness, which one is good DD?
A: These springs are less aggressive than the Yellow springs and they will not lower the car as much. The yellow springs are stiffer and drop the car 10mm lower than the Regular Guy springs.
