Please note:
- Upper mounts are supplied as noted in the Upper Mount Type option. Pillowball upper mounts add greater road feel for increased handling and accuracy but can result in torsional spring noise occasionally. There is no detriment to the function or safety of the coilovers. Returns under warranty for noises associated with the pillow ball upper mounts will not be considered. For investigative work related to coilover noise, workshop rates will apply if products are found to have no issues.
- For some vehicle model set-ups, the spring will be separate from the damper as noted in the Configuration Notes. For this type of setup, vehicle height can be modified via a supplied adjustable spring seat.
- Photos shown are inverted monotube design front and rear coilovers. Actual product will vary depending on vehicle model and coilover configuration chosen.
Unique Progressive-Digressive Damper Curve
Supashock’s unique progressive-to-digressive damping curve offers significant benefits by transitioning from progressive damping in soft settings to digressive damping in stiffer settings.
Enhanced Comfort in Soft Settings
Progressive damping provides smoother resistance at lower speeds, effectively absorbing small bumps and irregularities, ensuring a comfortable ride when you want it.
Improved Performance and Control in Stiff Settings
Digressive damping at higher stiffness settings delivers strong force at low shaft speeds, enhancing control for body roll, braking, and cornering. The damping force plateaus, preventing excessive harshness and allowing quick suspension reactions.
Ride Height Adjustment
Supashock Street & Track Coilovers feature fully-threaded damper bodies.
This allows you to adjust your overall damper length via the strut foot, and adjust your ride height via the spring perch.
Adjusting the spring perch alters the pre-load on the spring, however does not alter the spring rate which is determined by the design of the spring itself.
Monotube Damper Design
Supashock's advanced monotube damper gives you damping technology derived from nearly two-decades of V8 Supercars development.
Monotube damping separates the damper oil from the high-pressure nitrogen gas. If the two were able to mix (as they do in twin-tube dampers), the gas will cavitate within the oil causing 'damper fade,' severely impacting performance.
For ultimate performance, choose Supashock's Inverted Monotube damper option (pictured), available on selected vehicle models.
The inverted strut increases the rigidity of the unit, giving greater stength and performance.
