The 107 appears on circuit far more than you would expect from a city car. The 107 Trophy one-make series and various club grids run them because they are cheap to run and cheap to fix, and the lightness keeps the car genuinely quick at speeds that would feel slow in anything heavier. Track days see them pushed hard for the same reasons.
This subframe (SU-PE-17) bolts to the 107’s factory floor mounting points. The 291mm x 330mm bolt pattern fits Cobra base-mounted seats with a 291mm or 405mm wide runner handle: Monaco, Classic, Clubman, Monte Carlo, Stuttgart, Le Mans and the Roadster XL Plus all fit. The sliding runner is in the price. Other makers (Sparco, Planted, OMP, Recaro, Corbeau) sell the runner separately.
Cabin width
The 107 has a small interior. Measure the shoulder width at seat height before choosing a shell and compare it against the seat’s external width. The Cobra Classic is among the narrower options in the range at 480mm wide and was designed for tight classic car interiors, which makes it worth looking at first if cabin space is the main constraint.
Side-mounted seats (Nogaro, Suzuka T, Imola) need side mounts rather than a subframe. Ask before ordering if that is the direction.
Priced per frame. One frame fits one seat. Tell us the seat at checkout and we will confirm the complete kit.
