Real-world improvement you can feel

Dial in your preferred balance of comfort and control.

Expect tighter cornering, better steering response and a confident, planted feel compared to stock suspension.

We run this kit on customer builds and our own cars. Feedback is consistently excellent for both daily driving and spirited B road use, with the added bonus of adjustable stance to get the exact drop you want.
