The DP series is specially design for Drifting use purpose only. The damper valving and spring rate setup were tested and tuned by our cooperating Japanese and Taiwanese D1GP Drifting Race Driver.
For DP series, it use MONOTUBE INVERTED Damper in the Front or Rear of vehicles that use McPherson strut. As Inverted Dampers have advantage of decreasing unsprung weight by moving the greatest mass of the strut to the top where it connects to the sprung weight of the chassis, where weight can be more easily shaved. And also, the Inverted Dampers use a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue. Thus makes the Inverted Dampers ideal for Pro-Drift racing purpose as well.
For vehicle with Double Wishbone (A Arm) suspension, the damper valving and spring rate setup are also specially formulated for drifting purpose. It is also race proven by professional drifting driver.
[**Inverted Struts Dampers are ONLY provided with 12 Months limited warranty.**]
Both Front and Rear come standard with Pillowball Top Mount (Front McPherson Strut come standard with Camber plate if applicable; Rear McPherson Strut is without Camber plate as standard)
● DP-NN = Front and Rear both are Normal Strut Design
● DP-IN = Front INVERTED Strut Design / Rear Normal Strut or Sustech Up-Side Down strut design
● DP-II = Front and Rear both are INVERTED Strut Design
The DP Series Features :
MONOTUBE INVERTED Damper in the Front or Rear of vehicles that use McPherson strut. It can decrease unsprung weight by moving the greatest mass of strut to the top where it connects to the sprung weight of chassis, where weight can be more easily shaved
Inverted Dampers use a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue.
Advance design between outer and inner cartridge. So compare to other suspension brands, noise occur after longer period of time. Reduce the frequency for servicing of Inverted Dampers.
12 Months Limited Warranty on INVERTED Shock Damper.
Independent Ride Height Adjustment from Lower Mount. Not affecting spring compression and ride quality.
32-Levels Damping Force Adjustable. Simultaneous Compression / Rebound Adjustment with Linear Piston And Damping Curve
Reinforced Lower Mount - the lower mount has been reinforced for increase strength and durability to cope with the harsh operating on the track.
Camber Pillowball Top Mount - For DP Series, Pillowball Top Mount is standard at Front & Rear. For front McPherson strut, Pillowball Top Mount is with Camber plate if applicable, for better handling and more camber adjustment.
[Please NOTE, it is NORMAL that Pillowball Top Mount may have some rattling sound when driving. This does NOT affect performance of suspension. The warranty do NOT cover for Pillowball noise.]
Top Spring Bearing Cap - under Pillowball top mount to eliminate spring noise caused by cornering. This design enables spring and shock to perform together more effectively.
Friction Wave Washer - For MacPherson strut, Friction Wave Washer is installed between lower locking collar and bottom mount. Preventing lower locking collar become loose and lower bracket from spinning.
Rear Sustech Upside-Down Strut for selective vehicle models - Newly improved rear damping force adjustment method for vehicle models that previously cannot adjust rear damping by conventional design.
For some vehicle models, the chassis area on top of rear suspension strut is sealed with no holes. For conventional design, the damping cannot be adjusted without shock removal, or drill holes on chassis, which cause serious inconvenience.
With Sustech Upside-Down design, these models can adjust damping force VERY EASILY now.
