if you really want rib protection i would strongly suggest AGAINST the Sparco protector. It’s like cotton candy and you’ll be sorry. Spend a little more $$$ and get a good one.
What type kart do you have?
My suggestions are Phoenix (IMI sells them) Shift has a nice one and I had my MP customized (added .125″ lexan over the outside of the rib protector since I pulled right side then left side muscles/ribs/bones in my first year 😥 )
Anyone else???
