Championship Winning Performance:

ClubSpec Pro is for dedicated track enthusiasts that want a stiffer spring rate with a more track-oriented valving package. ClubSpec Pro was designed to be the fastest single adjustable damper on the market. Annex engineered their own double digressive race pistons and valving profiles that have been spec’d for every chassis. Clubspec Pro devours track curbing, however, care is still taken to ensure that ride quality is not lost.
Each set of Annex coilovers are hand-built by our California team to your exact needs.

Designed To Win:

Annex wins because of their extensive testing at tracks like Laguna Seca, Buttonwillow, or Thunderhill Raceway. Annex customers and Team Drivers have set numerous new lap time records on ClubSpec Pros™.

A great deal of attention is spent on enhancing the suspension’s performance over berms at the track and optimizing the vehicle’s responses to driver inputs and translational speed. While ClubSpec Pro was developed for the racetrack, you can still enjoy your vehicle without the drawbacks.

No Compromise:

Annex's team is relentless because we know that’s what it takes to win. This dedication is apparent when looking at the product itself, but just as impressive is the blood, sweat, and tears that have been poured in by the engineering team in pursuit of speed.

Extended Shock Bodies and Helper Springs:

ClubSpec Pro is equipped with extended shock bodys and helper springs for max droop and to maximize droop and grip over various track surfaces as standard. Competition cars need to use helper springs on a race-prepared suspension to help the car put the power down on corner exit!

Built To Last:

Engineered in-house in California, FastRoad Pro™ coilovers are hand-assembled using a network of quality suppliers located in North America, Europe, and Asia. Each shock is verified for performance on a shock dyno before being sent out. FastRoad Pro™ is a one-and-done suspension solution for the discerning sports car enthusiast that is made to last!

Spring Rates:

Annex spring rates provide great chassis control on track while specially valved internals reduce harshness and increase grip on bumpy terrain. Make no mistake, FastRoad Pro™ is for fast drivers just seeking to take some edge off. Fast Road Pro 4kg Front and 7kg Rear. Club Spec Pro 7kg Front and 11kg Rear.
