Lowering your 1200 by use of custom springs is the most elegant method. Full control over rate and length.
Contents |
Overview
Also see Coilovers which, though not lowering springs, are often fitted with an adustable spring perch for lowering/raising the Front Coil spring itself. You can also lower/raise the stock spring perch.
Many spring companies will make springs for the Datsun 1200 on request.
King Springs is one of the few companies that still list 1200 springs in their catalog. "Custom-designed coil springs can be made to order in most cases within 2 weeks."
