The (UL) Ultra-Lite Road/Track Coilovers are the ultimate in all-around performance and handling. It also features the aluminum pillow ball upper mounts and independent ride height and spring preload adjustability. For the serious Motorsports competitor, the UL version shares all the same features of the Race version but incorporates aluminum strut housings for an approximate 10% decrease in weight making them the competitor’s choice for those watching un-sprung weight. We have used these coilovers for dual duty, Drag and Autocross setups with great Success. With all the adjustment and spring options, it is possible to set up the vehicle to meet all situations and scenarios. Thought the strut housing is aluminum to save weight, the POWERTRIX (UL) Ultra-Lite coilovers use heat tempers forged steel for bottom mounting cups (where other companies use aluminum) 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 Road/Track Coilovers aluminum shock bodies make an entire assembly approximately 2-3 lbs. lighter than the standard (RT) Road/Track version coilover assembly. 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. 

Features List:
» Re-buildable/Replaceable Premium mono-tube aluminum strut Body
» Pillow ball upper mounts
» Race Grade 45mm strut piston
» 15 way strut damper adjustments
» Independent Ride height and Spring Preload adjustability 13kg/mm front and 11kg/mm rear 

All coilover kits are rebuild-able so it will be the last strut and spring combination you will ever need. Fine tuning of the suspension is also possible for any and every type of driving style, or motorsports events as custom spring rates are available from 3kg/mm (168 lbs/in) – 17kg/mm (952 lbs/in)
Note: + or – 2k on spring rate changes will require re-valving.
