CAR SEAT ADJUSTMENT RUNNER SET, MADE TO FIT UNDER INWARD POINTING TILLETT BRACKETS.
The lightweight double locking STRi seat runners can either bolt directly under inward pointing Tillett bracket sets, or under the Tillett seat types with base mountings using a TK5 spacer kit.
At only 24 mm tall, the runners do not lift the seat or driver. All Tillett runners are designed to sit in the gap that exists under the seat base, without raising the seat dome in which the driver sits. This is especially useful in vehicles with low roof heights where a roll bar or crash helmet may reduce the available space further. They give 12 cm of adjustment forward and back.
If a side mount seat is to be used along with Tillett brackets, the base hole spacing is 31.5 cm hole spacing front to back and side to side, matching Tillett bracket types which bend under the seat. They can also be used on the wider based XL, B8 and B9 seats by bending the handle a little.
The use of a TK5 fitting kit is advised with runners on all "bottom mount" B6 and W seats. This kit includes numerous nylon spacers to clear the mechanism from touching the composite and to allow a small amount of angle adjustment.
