The top and bottom carbon plates will work fine with a stick pack provided you do a little modding. I'll detail what I had to do later if I can remember, it's not hard and really all you need are some straps or tape to hold the battery in. You can also add an extra post to make it work. I believe there are some aftermarket carbon chassis for the Sprint 2 that still allow use of stick packs without modification. But stick packs definitely still work fine.

That said, they do look and feel great. I also have the carbon front and rear shock towers and they look great as well.
