RACELAND coilover install. The company did not have installation instructions for whatever reason, so I had to wing it. After a few trial and erros, I was finally able to figure them out. I kept the helper spring and used the OEM top hat along with the OEM top nut. The RACELAND top nut did not secure the strut bolt because it was unable to tighten to the lower threads. The rear perch and its three nuts were super confusing to mount but I was able to use my brain power and eventually figured those out as well. The nuts required two 15" adjustable wrenches to fasten. The complete install took me 1.5 days to figure out after getting frustrated and tired. After I figured out the configurations, it only took me 1 hour!!! They ride super smooth and are easy to adjust. I highly recommend the RACELAND coilover suspension!
