Tempest is NOT a low cross kart at all, they work best with high cross, i am on one myself and love it, would reccomend it to anyone, but OP said he wants an older, low cross kart. Phantom Nemesis comes to mind for me also, they are great karts and my brother in law is on one right now, and does good with it wherever we go.The Millenium Tempest V-2, loved that kart.
