Disclaimers
Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon ins sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

The brackets were exactly what I had in mind, and at a much more affordable price than Home Depot. They are sturdy and look amazing!

Nice brackets

The brackets look great and fit a 1x12 board perfectly. They've been installed for a few days and seem to be sturdy. So far, the only negative is the hardware, as other reviewers have mentioned. Initially, I had some trouble locating the stud and decided to use the drywall anchors. I got one bracket installed and the anchor was already pulling out of the wall. Overall, I think the brackets are great, but just use your own screws and drywall anchors (if needed).

I bought these for an alcove. The brackets came in great condition. I didnt notice any scratched. Mounting… the brackets are not centered on the wall, but are centered on the studs. I cant do anything about the stud placement. I bought a 2x8x10 board and cut it into 40 in sections. After placing the brackets on the wall the boards fit beautifully in place. (I used the long stud screws that came with the brackets) I havent screwed the boards to the wall (those screws also included) and may not. I like being able to pull a board out and run cables behind, if needed. I think the boards are sturdy enough that I wont have an issue with tipping, since the right most stud is at the corner of the wall.
