Powertrix Coilovers (UL) Ultra-Lite Road/Track
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”.
