Megan Racing introduces the new SPEC-RS Coil Over system features 32 levels of damper force adjustment, where compression and rebound adjustments are separate for increased tuning capability. The coil-over body also features separate spring perch adjustment and full shock height adjustment independent of spring pre-load to retain full suspension stroke while allowing the vehicle to be corner-balanced, which is often an integral part of suspension tuning as an aggressive alignment. These damper kits are then perfectly matched with front and rear Pillow Ball upper mounts for to reduce suspension deflection and camber plates are utilized for strut-type suspension applications. Compression and rebound settings are easily adjusted through a individual adjustment knobs located at the top of the damper for rebound adjustment and on the external reservoir for compression adjustments. With a twist of the knob, adjusting compression and rebound settings are simple to tune according to your driving style and suspension setup whether you are a professional certified mechanic or an automotive enthusiast with amateur mechanical skills. All of our dampers are capable of handling a +2kg/mm or -2kg/mm change in spring rates to further tune your suspension to your desired handling characteristics. Height adjustments are made with separate CNC-Machined locking spring perches for accuracy and smooth adjustment with separate damper shock length adjustment to retain full-stroke and allows for precision suspension tuning. The wide range of allowable ride-height adjustment allows you to lowering your center of gravity to gain full potential of your vehicle's handling capabilities. On applications utilizing strut-type suspension designs, the Megan Racing SPEC-RS Coil-over Damper Kits come with fully adjustable Pillow-Ball upper mount camber plates to easily tune and adjust your camber, giving you a competitive edge over other suspension setups. This allows you to tune your car for any ride height and still adjust camber to improve handling, vehicle predictability and tire wear, which is a great benefit both on the race-track and on the street. The quality and durability of the Megan Racing Damper kits are unmatched.
