Subie Bros is proud to bring you the best suspension components the market has to offer, including those made by FactionFab.

On this page, you are looking at their F-Spec Lowering Springs. These springs are precisely engineered to optimize the handling performance of your car by taking advantage of factory strut valving and travel through increased spring rate and mild drop. They feature a moderate drop, front and rear, to eliminate the factory uneven ride height while not over-lowering the car and effecting the factory suspension geometry and vehicles dynamic characteristics. The linear spring rate offers a predictable and controllable ride while offering a modest increase in spring rate to reduce body roll and provide better handling characteristics.

The FactionFab F-Spec Lowering Springs are a great way to get the perfect ride quality and aesthetic look out of your car while retaining drivability and functionality within a reasonable price.


Here are the details:

  • 1" front / 0.8" rear drop
  • Linear spring rate
  • 100% Engineered, tested, and manufactured in the USA
  • Spring silencers to reduce unwanted dynamic noise
  • Direct factory replacement
