Buddy Club has just made upgrading the seats on your 9th Gen Civic a whole lot easier. Buddy Club "Seat Rail" (Seat Base) kits are now available for all 9th Gen Civic models! The seat base kits are easy to install (no welding or cutting) and allow for you to quickly bolt on almost any aftermarket seat (Recaro, Sparco, MOMO, Buddy Club, etc.). They will also give you a lower driving position that will lower your center of gravity and may enhance your sensation of speed.
