PLM Universal Sliders Rails - Type I

The sliders feel really sturdy under my Sparco seat, and the universal bolt pattern meant I didn't have to drill any new holes. They slide smoothly with a nice positive lock, even after I tightened everything down.

These sliders are rock solid, and the fact they fit both side and bottom mounted seats saved me a ton of hassle. The adjustment is smooth and locks in tight with no play, so my racing seat doesn't budge an inch.

The mounting holes lined up perfectly with my side-mount seat brackets, which saved me a lot of drilling time. Only minor complaint is the finish could be a bit smoother on the edges, but for the price they work great.
