Making my life easier
I've always been very pleased with 1-A auto. I have not been able to put this suspension kit on with lower control arm bushings yet... But I just watched your accompanying videos on the order page (which I very much appreciate) I really like that you tell me on the videos exactly what size sockets and wrenches I need and on this particular case a very specific tightening/ torque procedure to make sure the bushing stays phased in. THANK YOU !
