XYZ Racing Circuit Master Coilovers — Mitsubishi ECLIPSE 2006-2012

The fourth-generation Eclipse’s grand touring brief gave Mitsubishi cover to specify suspension calibrated more for motorway composure than cornering load. Front-wheel drive, a kerb weight pushing 1,500 kilograms on the V6 GT, and stock damper rates tuned for compliance mean this chassis develops predictable understeer the moment circuit conditions demand genuine load transfer at the front axle. The Circuit Master changes that calculation.

Where the factory setup runs out of resolve under hard braking and corner entry, this kit replaces it with a correctly valved, fully adjustable system designed for sustained circuit sessions. The result is a chassis that loads the outside front with precision, responds to trail-braking inputs, and gives the driver enough feedback to work with – rather than manage – the Eclipse’s inherently nose-heavy balance.

What this coilover does for your 2006-2012 Mitsubishi Eclipse

The primary gain on a 2006-2012 Eclipse running the Circuit Master is controlled body roll, which directly reduces the lateral weight transfer that triggers the car’s default understeer response. The 3-knob adjustment system allows compression, rebound, and spring preload to be set independently, meaning the balance can be refined from session to session as tyres warm, surface conditions change, or setup experience builds. Standing height adjustment enables a genuine drop from the Eclipse’s tall factory ride height – a platform specified as a grand tourer first, where spring rates were chosen for road compliance rather than cornering precision. Lowering the centre of gravity on this chassis has a measurable effect on how quickly the car responds to steering inputs under load.

About the Circuit Master coilover

The Circuit Master sits at the top of the XYZ Racing range, covering competition applications that include Racing Spec, Drift Spec, and Tarmac Rally configurations. XYZ Racing teams have validated this damper on circuits worldwide, with the design reflecting development through live competition rather than simulated road testing. The defining engineering feature is the three-knob architecture built around a small-passage oil hole design: those three independent controls open up 9,720 distinct adjustment states, spanning the full range from a firmer road setting to a full competition configuration. The small oil passage does produce a light noise over large, abrupt bumps – this is an inherent characteristic of the design, not a mechanical fault. On a circuit, where track surface is consistent and free of the jarring compressions that trigger it, the characteristic simply doesn’t arise.

Fitment for the Mitsubishi Eclipse (2006-2012)

This kit is catalogued to chassis code MT16, covering the full fourth-generation Mitsubishi Eclipse production run from 2006 to 2012. It spans both the 2.4-litre four-cylinder and 3.8-litre V6 variants across all bodystyles produced in that period. Confirm your year and variant against the chassis code before ordering.
