It’s a great kit I love mine. They make the helmet super easy. Extra parts are for the different TKs so you can switch if you want to do a sandy down the road. I found the plastic to be very nice to work with due to the thickness. Be careful cutting but it is very sturdy. With that being said I did get a crack in my chest (my own fault, packing incident) so don’t be too careless. Seeing those pics makes me want to buy another one. Sent from my iPhone using Tapatalk
