Product Description
The SPARCO 600 Series seat bracket gives classic Porsche 911, 928, 944, 968, 964, and 993 owners a solid starting point for installing an aftermarket Sparco seat. It bolts to the factory floor mounting locations and creates a flat, rigid foundation for a street seat or a side-mount competition seat.
Each base is made from 3/16-inch steel and finished in black wrinkle powder coat. The outer mounting locations give wider side-mount seats more room, while the broad platform can also be drilled for a direct side-mount installation when getting the seat as low as possible matters. Choose the correct driver or passenger version for the side of the car you are building.
Building Your Porsche Seat Setup
This base is only one part of the installation. A bottom-mount Sparco street seat also needs sliders and bottom-mount hardware. A side-mount competition seat needs sliders, side mounts, and side-mount hardware. The slider set gives you forward and rearward adjustment. Direct-mounting side brackets to the base can lower the seat further, but that setup requires drilling and should be planned around your seat, helmet clearance, and driving position.
Pairs Well With
- SPARCO Track Set seat sliders 00493 - adds forward and rearward seat adjustment to the 600 Series base.
- SPARCO steel racing seat side mounts 004902 - connects a compatible side-mount competition seat to the Porsche seat base.
- SPARCO seat mounting hardware kits - choose the bottom-mount or side-mount hardware kit for your seat configuration.
