ST TA Height Adjustability: Polyamide Perch and KW Engineering

The ST TA Height Adjustable Coilover Kit provides precise, consistent ride height adjustment through the full spring perch mechanism with ST’s application-specific spring and damper calibration. The spring perch is manufactured from polyamide composite material with a stainless steel insert — a design that prevents the metal-on-metal corrosion that causes many coilover kits to seize at the height adjustment interface over time, particularly in climates with road salt and moisture. Galvanized zinc-coated steel struts provide corrosion protection for the damper body itself.

GD Platform Fitment and Long-Term Corrosion Resistance

Height adjustment on ST coilovers is done by rotating the lower spring perch on the damper body — the range is set specifically for the vehicle to provide useful lowering without compromising suspension travel. The polyamide composite perch with stainless insert means the height adjustment can be made and changed repeatedly without the seizing that plagues some coilovers. After any ride height adjustment, a four-wheel alignment is required to restore correct camber and toe. All mounting hardware, top mounts, and bump stop components for the complete installation are included.

Why Choose ST Suspensions

ST Suspensions is a European suspension brand backed by KW’s engineering and manufacturing infrastructure. Every ST coilover kit is designed, tested, and validated on KW’s shock dynos before shipping — the factory-recommended damper settings in each kit’s setup manual are the same settings the engineers verified on the dyno. ST coilovers are application-specific: spring rates, shock valving, and height adjustment range are calibrated for the specific vehicle rather than adapted from a universal platform. The polyamide composite spring perches with stainless steel inserts prevent the corrosion that causes many coilover kits to seize at the height adjustment interface over time. ST XTA kits add uniball camber-adjustable front top mounts — hardware typically found only on purpose-built track coilovers. RallySport Direct stocks ST because they represent well-engineered, reliable handling upgrades for drivers who want results without motorsport complexity.

The RallySport Take

The ST TA for the 2002-2007 WRX and 2004 STI is the height-adjustable coilover for GD platform owners who want improved ride height and consistent handling without the complexity of damper adjustment. The 5×100 bolt pattern fitment is specific to the GD chassis.
