Why this kit

H&R’s stabiliser technology is track-proven and road-ready. The two-way front adjustment lets you fine-tune understeer or oversteer to suit your tyres and driving style, while the matched 20 mm rear bar keeps the car planted and predictable. We run H&R bars on our own cars and our customers love the transformation in control and feel.
