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

The Corolla Altis E170’s torsion-beam rear reuses the factory damper mounting point rather than offering an adjustable geometry change, which means rear-end compliance has to come entirely from spring rate and damping tune – exactly what a tarmac rally stage across patched, cambered closed roads demands. XYZ Racing’s Tarmac Rally coilover is built around that constraint: a damper calibrated to absorb broken surfaces at speed while keeping the front end pointed through fast direction changes.

This is a stage-car spec, not a fast-road compromise. Where a road-biased set isolates the driver from what the tyre is doing, the Tarmac Rally kit keeps the contact patch loaded through compressions, camber changes and mid-corner ridges that closed-road tarmac stages throw at a front-driven Corolla.

What this coilover does for your 2013-2018 Toyota Corolla Altis E170

On the Altis E170’s OE-integrated rear, the biggest gain is composure over stage-surface imperfections – broken tarmac edges, patched sections, mid-corner ridges – without the body kicking sideways and costing you the line. The damper is calibrated to absorb hard hits from big compressions rather than transmitting them straight into the chassis, which keeps weight spread across all four contact patches instead of unloading one corner. That matters directly for traction off tight hairpins, where a front-driven Corolla on the wrong spring rate will simply spin the inside wheel and scrub time. Because the rear geometry stays factory, the front end carries more of the tuning workload; matching front and rear damping keeps the car settled rather than nervous when you’re back on the throttle mid-stage.

About the Tarmac Rally coilover

XYZ built the Tarmac Rally line specifically for sealed-stage work, where the road surface itself is the main variable rather than the corner. The valving is set up to take a hard, sudden hit – a pothole, a patched seam, a mid-stage compression – without spiking load through the body, which is what actually keeps the tyre gripping instead of skipping across the surface. That impact absorption is the whole point: uneven tarmac taken at speed will unsettle a soft or generic damper, so the internals here are tuned to soak up the big hits while still controlling body movement through faster transitions. The spring and damping combination for this kit is carried over from XYZ’s own tarmac rally outings rather than a lab spec sheet, which is why the bias sits toward high-speed compliance over outright low-speed stiffness. It’s a setup built to keep the car planted and predictable stage after stage, not just sharp for one clean pass of smooth tarmac.

Fitment for the Toyota COROLLA ALTIS E170 (OE Rr Integrated) (2013-2018)

This kit is coded TO28-1 for the Toyota Corolla Altis E170, covering the 2013 to 2018 model years. The OE Rr Integrated designation means the rear damper mounts into the factory mounting point, so there’s no separate top-mount conversion required at the back of the car. Confirm your Altis sits in the E170 generation and within the 2013-2018 build window before ordering, since this kit is chassis-specific.
