Flatirons Tuning Sub-frame lock-down kit

Both the Perrin Rear Sub-Frame Lock-down Kit, and the Cusco Rear Power Brace are designed to improve your car's handling by minimizing movement in the rear sub-frame. Both make a solid improvement, and do make the car feel more stable when cornering.

We have tested both on the Flatirons Tuning Project Car, and have found that though they work well on their own, they perfectly compliment each other, and reduce rear sub-frame flex almost to zero when used together. So we have decided to put them together in a kit for our customers.

Keep in mind that this will increase the noise and vibration that you hear in the cabin when driving.

Professional installation is strongly recommended.
