KartDen

I've been seeing more Kart Republic chassis around lately and I'm curious what the deal is with them. From what I understand a lot of kart brands end up tied back to the same Italian manufacturing groups even when the names look separate, so the badge alone doesn't always tell you who builds what. I'm still learning how the stiffness options actually change the way a chassis works on track though. Does anyone know who makes Kart Republic and whether they offer soft medium or hard setups?
