The kit that won it all.  THE standard of excellence.  The most popular chassis system in late-model road racing history.  Twelve years on the market and still dominant.  The proof is in the race records.  If you want to be consistently fast you need the World Challenge Kit.  If you don’t win with this, its time to check your driving.  There is no comparison for this one.  And where else can you find race parts with a lifetime warranty…really??
