ST's XTA Plus 3 Gives the GR Corolla Three-Way Adjustable Coilovers and Camber Plates

The GR Corolla came out of the box as a rally-bred hot hatch, and its owners have been taking it to track days and autocrosses ever since. ST Suspensions, the KW Group's more affordable brand, now has a serious coilover for it. PASMAG reported on August 19 that the ST XTA plus 3 is available for the pre-facelift Toyota GR Corolla.

The plus 3 name refers to three independent damper adjustments: low-speed compression, high-speed compression and low-speed rebound. There are 24 clicks each for low- and high-speed compression and 16 clicks for rebound. That is a level of separation you usually see on more expensive track dampers, and it lets you tune how the car handles curbs and bumps separately from how it handles body roll.

Camber and height

Up front, ST includes aluminum UNIBAL top mounts that also give camber adjustment. On a strut car like the GR Corolla, adding negative camber up front is one of the most effective ways to stop the outside front tire from rolling onto its shoulder in long corners.

Ride height is continuously adjustable, dropping the front 25 to 40 mm and the rear 25 to 45 mm, on motorsport springs. ST offers 18 colors through its Make It Yours program, with optional personalized spring lettering. The kit includes front struts, rear dampers, springs and the UNIBAL top mounts.

Why it matters

ST says the range of adjustment lets owners tailor the suspension “from everyday street use to more focused track-day setups.” That is the real use case for this car. Most GR Corollas are daily drivers that see a handful of track days a year, and three-way adjustment means the same coilover can be soft on the commute and tight at the track without a spring swap.

One thing to watch: PASMAG specifies the pre-facelift car, so check fitment carefully if your GR Corolla is a newer model year. ST sells worldwide through its authorized dealers. Pricing was not included in the report.
