Swift made Sport Springs keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best.

From HPDE events to SCCA competition, Swift Spec-R Sport Springs are made for the track enthusiast looking to take their vehicle to the next level.

Huge Improvement for Forester

Installed on 2007 Forester XT, stock struts with new top hats. Really improved the handling and the ride. The car is a bit lower to the ground, and feels tighter when turning. The springs handle bumps great. I've gotten compliments from my usual passengers.

2nd set and like them

Good springs very comfortable I wish the drop was a bit lower but works great for daily driving. I had them on a wrx and I still got understeer. I have them on my forester now and springs got rid od the floating feel.

Awesome level of sportiness and still comfortable

Removed the last bit of lean from the car, it handles much more like an STi now, but still very comfortable for daily driving and not too much of a height drop. I’m very much looking forward to my next autox event!


Wasn't looking for a huge drop, and these springs are perfect. Threw in a new set of shocks while I was under there and my WRX rides better than I thought possible. Only gripe isn't one of the springs but of the body of the car, the rear appears to sit lower than the front even though the body is level.

Fast delivery

fast delivery and good springs.
