Those are called rivets which are extremely durable and strong when installed correctly using a rivet gun, however, standard stainless bolts and nuts sourced from a local hardware store will work just as well.
I have purchased a short antenna, JCW black grill trim, and the magnetic grill badge mount kit all from Outmotoring. Speed and ease of ordering was fantastic. Couldn't be happier. Will always look to outmotoring first when ordering any parts.

Fantastic Customer Service from Aaron!! He is always helpful when I make a purchase and especially when I have a question and make a phone call, he's always helpful to answer my questions about an item or a purchase I've made. Very knowledgeable. Highly recommend OUTMOTORING!!

I’m on my 5th Mini and have been using OutMotoring since the 2nd for cosmetic upgrades. I’ve since decided to go for performance upgrades for my JCW and Aaron has been super helpful with suggestions for next steps. Very quick shipping when the items come directly from OM vs. the manufacturer. I’ll always check OM first if I need something for my Mini. Thanks!
