I have recently upgraded all my struts to coil overs and installed the z1 13" big break kit in the front and drilled and slotted rotors in the back. Now at speeds under 60mph breaks are perfect no shaking no rumbling perfect. At any speed above 60 mph car is smooth as glass but as soon as you touch the break pedal everything goes nuts. Steering wheel shakes car shakes feels like something is about to come off. But I have inspected every part of the suspension and all looks good and is tight. Please help with where to look next?
