XYZ Racing Circuit Master Coilovers — Toyota CELICA ST205 GT4 4WD (Fr Welding) 1993-1999

The ST205 Celica GT4’s full-time four-wheel-drive hardware sits ahead of the front axle line – the 3S-GTE turbo four, centre viscous coupling and front differential all packed into a nose that carries more mass than the front-drive Celicas it shares a shell with. XYZ Racing’s Circuit Master coilover kit is built around that weight distribution, giving the front end the control it needs to turn in cleanly under load rather than push wide into a corner. This is the Group A homologation Celica that Toyota Team Europe ran in the WRC, and the suspension underneath should match what the four-wheel-drive drivetrain is capable of.

Circuit Master is XYZ Racing’s sustained lap-time platform, built for drivers running repeated sessions rather than chasing one clean lap. On a coupling-driven all-wheel-drive system like the GT4’s, damping that stays consistent as oil temperature climbs across a session matters more than outright stiffness, and that consistency is what this kit is built to deliver.

What this coilover kit does for your 1993-1999 Toyota Celica ST205 GT4 4WD (Fr Welding)

With 9720 combinations across the Circuit Master’s three external adjustment knobs, you can set compression and rebound independently front and rear to correct the ST205’s nose-heavy balance without giving up traction from the GT4’s limited-slip rear axle. Firmer front compression control cuts the dive and float that comes from carrying turbo hardware and a viscous coupling ahead of the strut towers, sharpening turn-in on a chassis that was homologated for rough stages, not just smooth circuit tarmac. Rebound control keeps the front tyres loaded through direction changes instead of skipping over kerbs, while a firmer rear setting closes down the pitch that comes from four-wheel-drive acceleration out of slow corners. The result on track is a Celica GT4 that turns in on command and puts power down through all four contact patches without the wallow the factory struts allow at this power level.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, developed on international circuits and run by racing teams competing across disciplines from tarmac rally to drift. The three external adjustment knobs combine to give 9720 distinct damping settings, enough range to move from a compliant fast-road setup to a stiff, track-only one without swapping hardware. That range comes from a compact oil-hole metering design inside the damper body – on rough surfaces or sharp kerb strikes you may hear a faint noise as oil passes through the small internal passage, which is a normal characteristic of this damper rather than a fault. The kit is built specifically for circuit use, where the damper works hard for long, sustained periods rather than the occasional pothole a road car sees, and the internals reflect that brief rather than a fast-road compromise.

Fitment for the Toyota Celica ST205 GT4 4WD (Fr Welding) (1993-1999)

This kit is built for the Toyota Celica ST205 GT4 4WD, chassis code TO22, across the full 1993 to 1999 production run. The front top mount is a weld-in design rather than a bolt-in pillow ball, so front strut installation involves welding into the turret rather than a straight swap – factor that into your fitting time or book it in with a shop set up for welded top-mount work.
