Jim MacMahons ITB GT is probably the fastest ITB car in the north east and possibly the fastest IT Opel in the country. Though he's never raced against Bob D so it's hard to say. Anyway, he runs 200lb rear springs and a 500lb fiberglass front spring. The fiberglass springs originally came from RallyBob but are rumoured to be available from Suselbek now. They "borrowed" Bobs design without his permission, or at least that's my understanding....
