DON'T FORGET TO ADD THE SWIFT SPRINGS UPGRADE FOR THE BEST POSSIBLE RIDE QUALITY AND PERFORMANCE 

(See Details Below) 


The (UL) Ultra-Lite Coilover System is the ultimate in all-around performance and handling. It features the aluminum pillow ball upper mounts and independent ride height and spring pre-load adjust-ability. For the serious Motorsports competitor, the (UL) Coilover System incorporates a larger diameter premium racing damper/shock that features an aluminum housings for an approximate 10% decrease in weight making them the competitor’s choice for those watching un-sprung weight and allows for longer more consistent damping during competition/racing sessions. With all the adjustment and spring options, it is possible to set up the vehicle to meet all situations and scenarios.

The addition of Front Sealed Roller Bearing Top Spring Seats and Independent Rear Top Spring Seats eliminates spring bind and promotes proper rotation and response during steering in this McPherson Strut application and allows for proper movement/actuation of rear upper pillow ball mount. 

Though the strut housing of the damper is aluminum to save weight, the POWERTRIX (UL) Ultra-Lite Coilover System features heat tempers forged steel for bottom mounting cups for maximum strength where is it needed the most at the point of where the coilover assembly bolts to the hub of the car. 

 

The (UL) Ultra Lite Coilover Sytems' aluminum shock bodies make an entire assembly approximately 2-3 lbs. lighter. Though this does not sound like a lot, it can make a big difference performance-wise when the dynamics of sprung vs. un-sprung weight is considered. Sprung weight is defined as a parts weight while in motion or constant oscillation. Un-sprung weight is the actual weight of the part as it is at rest or not in motion. Sprung weight is calculated to be approximately 3-4 time its un-sprung weight. 

Therefore a coilover assemble that is 2-3 time lighter than another can be as much as 6-12 lbs. lighter while in motion, so calculating that savings on each corner of the car can be as much as 24-48 lbs. of weight savings which makes the car much more agile and more nimble on its "feet".

*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.
  

 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.

 

 


 HUB WELDING SERVICE

Hub welding service is available at $225.00 for both front spindles.

  1. Before sending your hubs / spindles, please clean all excessive dirt, debris and oil from the assemblies and be sure to remove all peripheral components such and heat shields, wheel bearings etc.
  1. Remove the strut cartridge and cut the strut tube just above the brake line bracket so we can reuse and weld that bracket to the new threaded adjustable damper tube. (see picture below)

 

 

 

 

 

 

 

 

 

 

Please send your cleaned and stripped hubs / spindles to:

POWERTRIX
9450 Mira Mesa Blvd. # C 447
San Diego CA 92126
 

 

PLEASE NOTE: Due to the larger size diameter of the coilover sleeve, damper and placement of spring, use of a 15mm-25mm front wheel spacers are recommended/required with the use of the stock wheels. Aftermarket wheels may not need spacers depending on offset.
