Yes, the 1000 has superior front suspension, like a Corvette. It has the same type of rear suspension as the 1200, but more expensively refined (iso-clamps and light alloy diffs). Add to that the 1000's substantial weight advantage and advanced rust protection (galvanized steel)

Suspension, motor and gearbox are just about same weight 1200/1000. So the 200 lb weight savings is in the chassis, which is narrower and shorter than the 1200

Does your racing class rules give any advantage to the 1000? Are short-wheelbase or low tare-weight cars penalized?
