homegrown sliders
I definitely angled mine up -- as to not lose out on any ground clearance, and to maximize protection of the body panels & doors. When deciding on what style to make, I liked the idea of a "kick-out" towards the rear:
However, when you have the "kick-out," you have to watch out for the "kick-back":
This is where I discovered the design flaw of these siders -- they do not go far enough back. I now know the importance of having the rock sliders go all the way from the front fender flares to the rear fender flares.
In the future, I'd like to either extend these sliders back another 4 inches, or start all over with a new design. So far that has been the only body damage received, and the sliders have protected me on many an occasion!
