Description
 

Capitalizing on the success of our Penske Racing Shock based suspension, we decided it was time to offer a lower priced alternative for the Lexus owner interested in achieving the ultimate in handling both on the road and on the track. Our goal was to achieve the instant turn-in response of small dedicated sports cars like the Porsche Cayman, at-the-limit balance and predictability at the track, all while maintaining poise and reasonable comfort on the street. In addition to our performance goals, we also wanted to break the cost barrier, and offer a top end, no compromise, 100% made in USA, single adjustable (rebound adjustment, fixed compression). We are proud to say that we have met all of our design goals, and are pleased to introduce a suspension package that is second only to our higher priced Penske Shock based alternative.

Summary of Features and Specs:

  • Afco Racing Shocks custom valved to our track tested specifications. Almost 20lbs weight savings over OEM components.
  • Hypercoil or Eibach ERS main and helper springs with Afco polymer couplers. Custom spring rates available. Hypercoil springs are US made, extremely high quality (tested within 2% spring rate), and found in virtually every form of racing, including IndyCar and NASCAR.
  • Rather than reuse OEM upper mounts, we designed our own upper spherical bearing aluminum top plates, featuring modular & rebuildable design for easy servicing. The other advantage of our upper mounts is that the spring perch is divorced from the spring, which allows completely linear spring motion and significant reduction in bending loads on the shock absorber (vs. KW, Ohlins, and other non-divorced setups).
  • Hypercoil or Eibach ERS main and helper springs with Afco polymer couplers and Delrin isolators on top and bottom perches. Custom spring rates available. Hypercoil springs are US made, extremely high quality (tested within 2% spring rate), and found in virtually every form of racing, including IndyCar and NASCAR.
  • Shocks are fully rebuildable. We offer a low cost in-house rebuild service. Rebuild is not required, but in order to retain the full performance of the shocks, we recommend servicing every 2 years.
  • Standard Spring rates (custom rates available upon request):
    • 900lbs(16kg) Front & 800lbs(14kg) Rear – Standard Road&Track setup
    • 1000lbs (18kg) Front & 900lbs(16kg) Rear – Aggressive Road&Track setup, for those using R-comp tires or slicks. Still very streetable
    • Every shock is hand made in and 100% Made in USA.

    After placing an order, we offer a 1-on-1 consultation in order to determine the best shock and spring specifications for your needs.

    We highly recommend to install our Ultimate Steering Response Product (USRS) in conjunction with this suspension to improve your steering response (offered as an option to this product).

    Note on Noise, Vibration, and Harshness (NVH): We have tested these coilovers on Pennsylvanias roughest pothole laden back roads. Our customers can expect that these coilovers are vibration free, and can be adjusted to ride comfortably on the street. On most roads, they do not make any discernible noise. On rough back roads, some noise, particularly at low engine speeds when the exhaust is quiet, is to be expected. Our upper and lower mounts use spherical bearings rather than sloppy rubber bushings to offer no-compromise response and feedback. Even though we do not use rubber bushings on the suspension mounting points, we can assure our customers that any increase in noise is very minor.

    All components in this product are proudly engineered and manufactured here in the United States of America.
