About this product
These Yellow Speed Inverted Pro Street coilovers fit the 2011-2014 Subaru WRX STI (GVB/GVF(4door)). They have the characteristics of the Dynamic Pro Sport coilovers with a 55mm inverted monotube shock body for added strength and comfort. This is part number YS01-SB-DPS021-i-PBU.
The inverted monotube design improves handling and comfort, holds more shock fluid to help dissipate heat, and the larger shock body prevents premature shaft seal failure. Rebound and compression damping are adjusted together in 33 levels, from the bottom of the coilover. The rear uses a Sustech inverted damper where an application cannot be adjusted without removing the coilover. Each application is test fit and road tested.

- 33 levels of damping adjustment, rebound and compression adjusted together
