- BUILT TO LAST -- Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the long-lasting premium liquid metallic finish and polyvinyl protective boot ensures longer life
- SMOOTH PERFORMANCE -- Polyurethane rebound bumper and bushings and graphite-filled fluon-banded piston help absorb ride harshness and enhance responsiveness to changing road conditions for an overall smoother ride
- NINE LEVELS OF PERFORMANCE -- Nine-position easy-to-adjust knob allows customized damping control and firmness for on-road and off-road flexibility
- REDUCES FADE -- Nitrogen gas pressurized to 45 or 60 PSI to minimize air-to-oil mixture and reduce damping performance fade and foaming

Why Drivers Choose FAST of West Chester
-
I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
support my builds going forward.
Donald Wojnar -
I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.
Adam Cranston -
The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.
Bryce Budd -
This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.
William Brunell -
Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
and what I needed to get where I want to be with it. I'd recommend them
to any car enthusiast.
