No, I used to sell Toyota's at Lander's in Little Rock. The main man in the tire and alignment shop did it for me. They put it on the alignment rack, jacked up the front, pulled the old and installed the new with an alignment in less than an hour! Having a pro with a spring press is highly recommended. Unless you know what you are doing, I would not mess with those coil-overs!!! I will put the ones on the rear myself unless I get some heavier springs to go with it. You can tell a huge difference in the damping between the Billies and the stock's in the rear. It is amazing!!!
