Thanks for posting this. I'm considering a set of RokBlokz for this winter. Lots of snow/slush in the Buffalo winters, and last year it started to really accumulate on the front edge of the steps. To the point I thought I was going to break off the lower plastic door trim when opening the door. Hoping some large coverage flaps like these will keep the winter buildup off the steps.Ended up giving the RokBlokz a shot hoping I could modify them to work. Sure enough, a single hole added in rear worked perfect. I’m sure RokBlokz will perfect them whenever they get an R1S in for R&D, but this works great if you’re willing to drill a hole in flap. Fronts fit perfect, so only rear needs modified.
