I'm in the process installing them now. It's taken a little bit of effort to install them because of the position my seat is in respect to the holes. Just behind the holes my seat starts to curve. When done I believe there going to be awesome. I must say trying to talk to someone was a pain. Absolutely no response from anyone I reached out to including Fast Adjusters own website. I went ahead and took a chance on the model I needed and thank goodness I made the right choice. It sucks because I won't be able to test them until late March when our track reopens.
