I have a set of Gen Mar 38mm risers for 2008-14 C14
I just have the risers no bolts. If you can supply your own longer fasteners they should work no prob. I think gen mar's website states 80mm bolts. I had a hard time finding 80mm so I never installed them. I bought them from another member here, just the risers in 2011. Now they are just collecting dust
$40 shipped. Pay pal preferred. Thanks!
