Adjustments

  It's full-length adjustment system keep ride height and preload adjustments separate by having easily adjustable length shock bodies. This feature allows you to make quick setup changes with the included forged spanner and also allows corner weighting without affecting spring preload. The 16 position damping force adjuster is an easily reached knob on  top oh each shock. Typically you can run 1-8 (stiff) damper settings for track use with race tires then in seconds adjust to 10-16 (softer) for the ride home from the track. No need to crawl under the car or take the shock apart!

Tuning

  The standard Flex spring rates are 7/5kg, equivalent to 396 in/lbs front, 280 in/lbs rear.  For a daily driver and occasional drifting, autocross or track days, the standard Flex 7/5kg springs are great. For a more competition oriented setup with wider race tires I recommend increasing the front spring rate between 9kg-12kg/504-672# and rear spring between 6-7kg/336-396# ($40 per spring). Custom valving available for $130 per shock.

 For a no fuss installation, set them up exactly how the included instructions show and you'll have an awesome street/track high performance suspension.
