Been wanting to clean up the fender for two years.... bit the bullet and using the Abbatte discount, ordered the Seibon CF garnish. I didn't do the formal install which requires taking off the fenders. The pieces have mounting posts (threaded) with washer and nuts. It was going to cost about $250 in labor to do this. So, after taking off the OEM garnish, saw that if I used thick 3m 2-sided mounting tape -- strategically placed in areas on the back -- I could do the install w/o taking off the fender. I guess time will tell if this is truly a rock-solid mounting method.
I am NOT going to miss the OEM opposing piston logo piece...
