Concerning the kit, just ask the shop that delivered your bar.
I'm riding a bar without the kit for 1,5 year now and haven't experienced any problems, so it will not happen at any bar.

I've been riding the bar since it came out and never had a problem.
For peace of mind, ask your Zeeko representative for the free kit!
