The Sparco seat sliding runner kit (0049306) is the straightforward way to add fore-aft adjustment to a base-mounted sport seat. It bolts directly to Sparco’s 345mm x 271mm bolt pattern and works with any base-mount seat that uses the same platform, including OMP and Corbeau base-mount reclining and bucket seats alongside Sparco’s own range.
Pricing is per single runner kit, which fits one seat. If you’re fitting both sides, the two-runner bundle (SS0049302-X2) is the easier order.
These are steel and are sold as a non-FIA fitment. That means they’re fine for road use and track days, but not for cars competing under FIA regulations where the homologated fixing alone must carry the load. For competition use, the seat usually bolts directly to a homologated sub-frame without a runner in between.
The most common use case is kit cars and conversions where the standard runners are gone and you need a clean way to mount the seat with some adjustment. For a standard road car using one of Sparco’s vehicle-specific sub-frames, many people find they don’t need runners at all because the fixed position is already dialled in.
These will not fit side-mount seats. Side-mount seats use a bracket system that attaches to the sides of the shell, and a floor runner has no role in that setup. If you’re fitting a side-mount seat, see the FIA steel side mounts (SS004902) instead.
We carry these from stock. If you’re fitting them to a base-mount seat that isn’t from Sparco, OMP, or Corbeau, it’s worth confirming the bolt pattern matches the standard 345mm x 271mm before ordering.
