XYZ Racing Street Advanced Coilovers — Toyota CELICA ST185 4WD TURBO (Mcpherson Type) 1989-1993

The ST185 Celica GT-Four carries real mass over its front axle – the transverse 3S-GTE, the transfer case and the front differential all sit ahead of the firewall – so on tired factory struts the car washes wide into understeer long before the turbo runs out of puff. The XYZ Racing Street Advanced coilover for the Toyota Celica ST185 4WD Turbo is built to put that nose back under control without turning a usable road car into a cement mixer.

This is the road-biased setup in the XYZ range: height adjustment to set a sensible stance over the MacPherson strut front end, and damping you can soften for a broken B-road or firm up for a dry track session. For an early-90s rally homologation 4WD that owners actually still drive in 2026, that adjustability matters more than outright stiffness.

What this coilover does for your 1989-1993 Toyota Celica ST185 4WD Turbo

Drop the ride height and you cut the body roll that lets the GT-Four’s front end push under load, sharpening turn-in on a chassis that was always fighting its own weight distribution. The 720-way damping adjustment lets you run a compliant setting for daily use and a tauter one for a track day, so the full-time 4WD traction works with a tied-down body rather than against a wallowing one. Set the corner heights properly and you also get back the consistent geometry the standard struts lose with age. The result is a Celica ST185 that turns when you ask it to and stays composed mid-corner when the boost arrives.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most popular product and its everyday-usable option, refined over years by the company’s engineering team and validated through their international race programme. It is aimed squarely at the driver who wants one suspension setup for normal road use with the headroom for the occasional track day. The headline feature is 720 individual damping settings from a single adjuster, giving a genuinely wide spread between comfort and control rather than a token soft-or-hard switch. Combined with threaded ride-height adjustment, it lets you tune stance and damping independently to suit the ST185’s nose-heavy 4WD turbo layout. It is the kit for an owner who wants sharper handling without sacrificing the ability to drive the car every day.
