The C5/C6 (R/T) Road/Track Coilovers feature our robust premium grade slim line mono tube dampers/shocks specifically designed for the C5/C6 chassis and include pillow ball upper mounts to transfer more suspension energy through the strut piston shaft increasing the efficiency of the overall suspension duty. Full forged steel threaded shock bodies for independent ride height and spring preload adjust-ability and linear springs make the (R/T) Coilover System an "All Business" tool for Auto crossing and Road Racing with the ability to go to and from the track on. Designed for the true performance enthusiast looking for the extra edge during track time yet offers a ride quality comfortable enough to run on the street on a daily basis.
Powertrix has an excellent 15 year reputation for building high quality suspension for both on the Race Track and for Street use. Mostly known for developing Coilover Systems for high 500+ horsepower Nissan Z cars, they have expanded into the Toyota, Lexus, Mazda, and Subaru markets. And most recently in LS equipped FD3Ss.
NOW OFFERING THIS PREMIUM COILOVERS SYSTEM AS A DIRECT BOLT ON INSTALLATION FOR CHEVROLET CORVETTE C5/C6 OWNERS.
Performance-wise, we are happy to compare our dampers/shocks vs. the likes and quality of OHLINs dampers/shocks. (See attached shock dyno comparison)
In viewing the below shock dyno, you will notice the similarities of the curves however what stands out the most is how our dampers have a larger range of adjustments allowing more stiffer performance oriented settings than the other damper. This shock dyno was performed by a third party non-biased tester.

Standard 7.5kg/mm (420 ft/lbs)/10kg/mm (560 ft/lbs) Spring Rates - 200mm front and rear spring length.*Custom Swift Spring Rates also Available *All coilover kits are rebuild-able / replace-able so it can be last strut and spring combination ever needed. Fine tuning of the suspension is also possible for any and every type of driving style, or motorsport event as custom spring rates are available from 3kg/mm (168 lbs/in) – 17kg/mm (952 lbs/in) Note: + or – 2 kg/mm on spring rate changes will require re-valving.
FEATURES
- Bushing Mount:
Upgraded Bushing durometer for increased suspension performance and durability yet still maintaining comfort.
- (BLACK) Magnicoated Damper Housings
Dampers / Shocks will now be (BLACK) Magnicoated. Magnicoating is a high performance corrosion protection coating.
It is a chrome-free duplex coating engineered specifically for automotive use and other structural components. This process is much stronger than conventional e-coat (zinc style plating), and will provide extended field protection, and minimizes the degradation of the structure - ability of the material.
- (PPI) Dust Boots
(PPI) Polymer Plastic Injected dust boots – These plastic injected boots are proven to be more durable and will resist breakdown due to the outside elements.
UPGRADE to The SWIFT Springs advantage: 
POWERTRIX has partnered with SWIFT Springs to offer the very best in suspension spring technology. SWIFT spring composition is manufactured using their own proprietary steel alloy "HS5.TW". This material was formulated in order to maintain the 4 major performance factors listed below, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions.
“SWIFT springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring the their product separates them from the standard market."
The 4 Factors that separate Swift from the rest of the spring industry:
1. Consistent spring rate throughout the stroke = more consistent performance
2. The largest amount of stroke to maximize suspension motion.
3. The highest durability against loss of spring height = excellent material memory prevents springs sag over.
4. Extremely light weight to reduce sprung weight increasing over all agility.
