A few weeks ago it was installed by a pro to be able to adjust the rear camber as 80% of new cars don't have this option. I had very worn tires on the inside and changing tires too early cost me a lot of money. I am very happy with the installation. I have read many blogs about this rebuild and chose this manufacturer because of the excellent quality of racing performance and USA manufacturing. The SPC website has a nice installation video that says an experienced man can replace it in about 45 minutes. apart from whether you have the right tools, which unfortunately I don't have. Got a few quotes from the store and both said an hour per side plus 4 wheel camber adjustment. I went to a local mechanic rather than a Honda dealership as this new part is non-OEM and to be honest dealers hire technicians who are not experienced mechanics. I was afraid I would dice with the dealer service center and end up paying more than the quoted estimate. My local mechanic did all the work for the price quoted! It ended up costing about $380 for left and right assembly and 4 wheel alignment.
