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.

Fastest Single Adjustable Damper:

Exotic materials and processes, exquisite engineering, and unrivaled performance that simply can’t be matched by mass-produced dampers.

Real Custom Valving:

Unlike other suspension companies, Annex doesn’t rely on just subjective feedback or off-the-shelf valving for any of our products. Annex uses their in-house data and our own mathematical models to create custom valving based on the unique attributes of your race car or class rules. No guesswork, just race winning performance.

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!

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.
