Brand: Sabelt
These strong seat brackets from Sabelt fit most side-mount racing seats with 290mm bolt hole spacing (including MOMO, OMP, and Sparco FIA 8855-1999 seats with fiberglass or carbon fiber shells).
Five front and four rear mounting holes allow you to fine-tune the height and seating angle to your liking. Three sets of mounting holes in the bottom provide flexibility in the fore-and-aft location in the car. The low-cut center minimizes interference with your lap belts. Black powdercoated steel brackets are 3mm thick. FIA approved. Sold in pairs (enough to mount one seat).
