Comfort Sport Inverted Series

CSI Series

It is based on CS series, but use MONO-TUBE INVERTED Damper in the Front or Rear of vehicles that use McPherson strut. Although it can be used for Street use purpose, but Inverted Damper have some good advantages that make it ideal for Race use purpose as well.

 

Standard setup is for Street use purpose and come standard with Rubber Top Mount at Front and Rear. If for Race use purpose, Front or Rear can upgrade to Pillowball top mount (Front with Camber plate if applicable) at EXTRA Cost. On vehicles that ONLY Front with Inverted struts, rear are provided with CS Series in Normal Strut design or Sustech Up-Side Down design depend on vehicle application.

 ● CSI-IN = Front INVERTED Strut Design / Rear Normal Strut or Sustech Up-Side Down strut design

 ● CSI-II   = Front and Rear both are INVERTED Strut Design

Advantage of Inverted Damper: Inverted Dampers are useful in decreasing 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. The Inverted Dampers use a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue. Therefore Inverted Dampers are ideal for racing use as well. [Please NOTE, the higher lateral loads are ONLY prevalent on McPherson strut suspension, NOT on Double Wishbone (A-Arm) suspension.]

However, the Inverted Damper require servicing and re-apply grease after certain period of time. It is NORMAL for Inverted Damper to have noise generate from damper after some months of constant usage (this happen to all other suspension brands as well). It does NOT mean the damper is defected or lost it's performance. It just require servicing, which will need to strip out the outer and inner damper cartridge, clean the old grease, then re-apply new grease between outer and inner damper cartridge. With proper servicing, the noise will be gone. As the noise do NOT mean the suspension defect or lost function, therefore it is NOT covered by Warranty.
[
**Inverted Struts Dampers are ONLY provided with 12 Months limited warranty.**]

We have 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.

​ The CSI 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

  • Rubber Top Mount - For vehicle with Front McPherson strut, if customer want more comfort and less noise ride, they can choose CS-A with front Rubber Top Mount.

  • Camber Pillowball Top Mount - For Race use purpose, McPherson strut can upgrade to Pillowball Top Mount at extra cost (Front 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.
