Our adjustable seat brace is engineered to extend the protection of your roll cage to the back of your seat. The Brey-Krause adjustable seat brace is designed to fit 1 3/4", 1 5/8" and 1" diameter roll bars. The mounting bracket is secured with bolts through two holes which are drilled through the roll bar tubing. Once bolted to the roll bar, the seat brace can be adjusted fore, aft, up or down. This seat brace is designed for one piece (i.e. non-reclining) racing seats. The R-9019 is recommended for Porsche reclining seats.
You'll need the bolt in kit r9021. Bolts to 1-3/4" tubing without shims. Shims are included for 1-5/8" and 1-1/2" tubing.
