They have a long way to go with the development of their products here in the states and specifically on the 5th gen 4R. Although they are competitively priced, they are overweight and hardly qualify as high-clearance.
I dealt with them a year ago when inquiring about a set of sliders. I paid my $700 for a set that was aesthetically pleasing but offered as much protection as paper shoes. They hugged the vehicle too tightly and any hard impact would shove the slider directly into the body of the truck.
Ask me how I learned that one...
Their correspondence is for nil as well as any etiquette is basically nonexistent.
