Thanks for the support guys. The pads with the missing corner are fine. We see that type of thing on many different brands among customers. A little chunking or crumbling on the edges is no bid deal, and we wouldn't anticipate any problems with running them.
As noted, we typically recommend starting with the same pad compound front and rear, then tailoring feel to taste and results. Most people tend to stick with the same compound on both ends.
If you guys have any pictures or feedback on our brake kit,
please email them to me! I'm constantly looking for material for our social media, blog, etc. Thanks again gents!
