An inverted monotube front strut carries the cornering loads of the GR Corolla while an upright monotube damper is used at the rear, both with 30 steps of damping force adjustment. HKS runs an unusual rear biased spring pairing here at 7.0 kgf/mm front and 9.0 kgf/mm rear, with a soft 7.6 N/mm front helper spring and a 19.8 N/mm rear helper to keep the springs seated at full droop. Full-length shock body adjustment covers stock ride height down to 49 mm lower in front and 71 mm lower at the rear. Reinforced rubber upper mounts, Dual PVS valving, the WR Needle soft-range circuit and PNE corrosion-resistant plating are standard.
