Does anyone know much about this kit? Or have any experience running it? Having had them fitted, they work... They definitely stop the car quite well. Only issue is, under light braking the pedal and wheel judders around quite a bit. Once I break heavily the juddering goes away and all is fine. Air in the lines? Warped disks? If it is warped disks, anyone know if I can run different brake disks other than the ones Forge supply?
