THE POWERTRIX UL COILOVERS SYSTEM will be the most reliable, most customize-able system for your R35 Nissan GTR. Whether you want better ride quality or need to rip up the track or somewhere in between, we can custom assemble just what your are looking for without breaking the bank through various spring choices and top hat configurations coupled with definitive wider range 15 way damper settings. 

With over 18 years of coilovers manufacturing for the Nissan Twin Turbo Z sports car platforms with proven reliability to with stand over 100,000 miles of street, track, and drifting abuse, our Ultra Lite Dampers are custom valved with specific stroke and casing lengths design to maximize the performance and handling of your R35 GTR.

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/racings sessions. With all the adjustment and spring options, it is possible to set up the vehicle to meet all situations and scenarios. 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".
