DON'T FORGET TO ADD THE SWIFT SPRINGS UPGRADE FOR THE BEST POSSIBLE RIDE QUALITY AND PERFORMANCE
(See Details Below)
SUBARU WRX/STI (2015+)
The (R/T) Road/Track Coilovers feature the same robust premium grade mono tube dampers/shocks as our (SS) Sport Street Coilovers system but adds the increased performance dimension of 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 adjustability and 8k/6k 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.

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.
