Mazda RX8 coilovers Australia enthusiasts need for both series are here: the KTS SC Damper System is a fully adjustable coilover set covering every RX8 from 2003 through 2012. Built around a monotube shock housed in a plated steel shell, height and damping are independently adjustable. The setup genuinely responds to how and where you drive. Performance springs are included in the kit.

Mazda RX8 Coilovers Australia: KTS SC Damper Features

  • Monotube shock construction sits inside a plated steel shell case, giving a responsive damping feel that a twin-tube design typically cannot match at this price point.
  • Ride height adjusts via a full tap system on both axles. It does so without altering spring length or shock stroke, keeping geometry predictable across the adjustment range.
  • Both front and rear units offer 15-way damping adjustment. Soften the car for daily commuting, then firm it back up before a track day.
  • Rated spring rates are 10 kgf/mm front and 7 kgf/mm rear. These performance-biased figures suit the RX8’s balanced weight distribution well.
  • Finally, oil capacity is increased over a standard damper. This keeps damping force stable and consistent even when the oil reaches high operating temperatures.

For rotary enthusiasts looking at Mazda RX8 coilovers in Australia, the difference shows up the moment the road tightens. Turn-in sharpens, body roll tightens, and the RX8 settles into corners with a confidence the standard suspension never quite delivers. On the daily commute, the 15-way adjustment means you are not locked into a firm race setup. This kit covers Series 1 and Series 2 cars without modification.

The KTS SC Damper prioritises adjustability and track-capable damping over refined road compliance. That makes it the stronger fit for drivers who want more control over their setup at a lower outlay. If maximum refinement matters most, the OHLINS MAS-MI00S1 Road and Track Coilover Suspension takes a different philosophy. Full manufacturer specifications are available at the KTS official website.

Chassis bracing is the natural next step when fitting RX8 coilovers in Australia. The CUSCO Strut Brace Type OS (Front) with Brake Cylinder Stopper stiffens the front end to match the improved body control the coilovers bring. The AUTOEXE Lower Arm Bar (Front) reduces lateral subframe flex, helping the new suspension geometry work as intended. Pair either brace with the AUTOEXE Brake Rotors (Sport, 1-Piece) to round out the handling upgrade with braking performance that keeps pace.

Frequently Asked Questions

Do the KTS SC Damper coilovers fit both Series 1 and Series 2 RX8 models?

Yes, the KTS SC Damper System is a single kit that covers all RX8 models from 2003 through to 2012, including both Series 1 (2003-2008) and Series 2 (2009-2012). No separate kit is required per generation.

Are the ride height and damper firmness adjusted independently or together?

They are fully independent adjustments. You can set your preferred ride height separately from damper firmness, which means you can dial in your stance for street or track use without those two settings being linked to each other.

How does the KTS SC Damper compare to the AUTOEXE suspension option for the RX8?

The AUTOEXE suspension is tuned for refinement, with strengths in quietness, smoothness and low-speed bump absorption. The KTS SC Damper is the more overtly sporting choice, offering greater adjustability and a more track-capable character. Both suit road use well, so the decision comes down to whether you prioritise comfort and refinement or adjustability and sports performance.

Can I use these coilovers comfortably on the street as well as on track?

Yes. The separate damper firmness adjustment lets you soften the setup for daily commuting and firm it back up for weekend or track driving. Store owner Josh notes the SC Damper makes the RX8 feel considerably sportier through corners while remaining genuinely comfortable on everyday roads.

Why are the KTS SC Damper coilovers more affordable than some rivals if they are built in Japan?

KTS focuses its engineering budget on suspension performance rather than premium cosmetic finishing, and that is where much of the price saving comes from. The reduced visual presentation does not represent a sacrifice in suspension capability.

What chassis upgrades pair well with the KTS SC Damper coilovers?

The CUSCO Strut Brace Type OS (Front) with Brake Cylinder Stopper tightens the front end to match the improved body control the coilovers deliver. The AUTOEXE Lower Arm Bar (Front) reduces lateral flex at the subframe, helping the new suspension geometry work as intended. These two bracing pieces complete the handling upgrade logically.

Where are the KTS SC Damper coilovers manufactured?

The KTS SC Damper System is built in Japan. Full manufacturer specifications are available on the KTS official website.
