Andrew,
Thank you for your 5 Star Review! We are glad to hear that you are satisfied with the FactionFab F-Spec Coilover Kit for your 2015-2021 WRX/STI! Coilovers can offer improved handling and adjustability compared to stock suspension, and it is great to hear that you have noticed a difference in ride stiffness when adjusting the damping settings. The overall quality and fit of the parts is also important, and it's good to know that FactionFab has met your expectations in this regard. While you have not compared them to other coilovers, it is still valuable feedback to share your positive experience with the FactionFab F-Spec Coilover Kit. Enjoy your improved suspension setup!
Regards,
