XYZ Racing Gravel Rally Coilovers — Toyota COROLLA ALTIS E170 (OE Rear Integrated) 2013-2018

Gravel rally stages throw everything at a car’s suspension at once – washboard ruts, sudden compression over crests, and traction that shifts from loose sandstone to slick silt within a single corner. The Corolla Altis E170, running the OE rear-integrated mounting set-up, needs dampers that can absorb that chaos without the chassis pitching or the rear axle skipping sideways under power.

XYZ Racing’s Gravel Rally coilover is built specifically for that discipline, not adapted from a road or circuit design. It is the kit for owners running a Toyota Corolla Altis E170 in gravel-stage competition or rallycross, where ground clearance, wheel travel and damping consistency over rough surfaces matter more than outright stiffness.

What this coilover does for your 2013-2018 Toyota Corolla Altis E170 (OE Rr Integrated)

Fitted to a 2013-2018 Corolla Altis E170, this coilover changes how the car handles a gravel stage rather than just how it rides on the road. The long-stroke damper and long spring combination absorbs chassis vibration before it reaches the body shell, so high-speed bumps and compressions get soaked up instead of kicking back through the wheel. That extra stroke also means the axle keeps tracking the ground surface longer over crests and dips, which keeps the tyres loaded and the car pointing where you steered it. Under hard cornering, where lateral G-force loads the outside dampers hardest, the kit is built to hold its damping character through a stage rather than lose it partway, so the balance you set at the start is close to what you have at the finish.

About the Gravel Rally coilover

XYZ Racing developed the Gravel Rally coilover specifically for rally and rallycross use, where surface grip changes from one corner to the next. Its inverted-tube design flips the conventional damper layout to cope better with the repeated impacts and directional side loads that sandstone, snow and silt surfaces each throw at a chassis in a different way. Stroke length and spring length are both extended well beyond a road-going coilover’s, giving the damper room to work through large vertical wheel movement without bottoming out or losing control of the wheel on a jump landing or a rutted compression. Every spring rate offered in the range has been set and verified by an XYZ Racing rally team on actual gravel stages, rather than calculated on paper, so the rates reflect what holds up under competition rather than a lab estimate.

Fitment for the Toyota Corolla Altis E170 (OE Rr Integrated) (2013-2018)

This kit is built for the Toyota Corolla Altis E170, chassis code TO28-1, across the 2013 to 2018 model years, using the OE rear-integrated mounting set-up rather than a modified rear end. Confirm your Altis falls within that build range before ordering, since Toyota revised the E170 platform’s rear suspension mounting partway through its production run.
