These rear knuckles by Destroy or Die are designed to correct the roll centre by 30mm. This reduces helps to lower the centre of gravity without increasing camber, greatly improving the suspension dynamics and reducing tyre wear. The super knuckles provide a second set of caliper mounting points to add a second caliper for a hydraulic handbrake so that it doesn’t pump the brake pedal when pulled.

Engineered to use OEM wheel bearings, these Super Knuckles are an excellent upgrade for your MX-5. OEM bushes are utilised, allowing you to easily upgrade or replace them as required. Bushes are not included with the Super Knuckes but are included with the Destroy or Die rear upper camber arms.
