The new Max IV GT 20 Spec coilovers from HKS offer a significant improvement over the existing GT series coilovers. The old GT coilovers did a great job at lowering down the vehicle and improving handling over the stock suspension, but with revised spring rates and damping, the GT 20 Spec preserves comfort while further improving handling and driveability. These coilovers feature an inverted single tube design which greatly improves the rigidity and feedback through the shock. Multiple valve shims of differing size and thickness are stacked around the piston internally, which generates a resistance to increase the damping force. This gives you full control both at high and low speeds.
- 9 kg/mm front / 7 kg/mm rear spring rate
- 220mm front / 170mm rear springs
- -31mm front / -34mm rear height adjustment
- Rubber front and rear upper mounts
