I've fitted the adjustable hindge pin braces both front and rear to my buggy.
There very nicely made and offer alot of adjustment.
As a bonus with the inserts being replacable you can quickly tighten up any slop that might develop after a crash or prolonged use ......
At the front you "can" also use the different blocks to make roll center adjustments something i believe is over looked in the manual, admittedly you have to be within a certain kick up range to be able to do it though, I guess thats why its not covered.
Anyway IMO a very worth while investment
