I really like the idea that Nemesis includes new mounting brackets. It definitely makes the price seem better. What's annoying is that for the additional "flare" they don't really explain how it attaches. Seems like it bolts on, but they say no drilling? Is it easy to take on and off? What are the "skeletos?"
Oh no, there is absolutely drilling. It mounts using countersunk hardware.
Skelotos is extra ribbing inside the flare to reinforce the outer lip. I went without, but I’ve also bent my rear flare, but I’d rather the flare bend than it push harder into the body.
