BerlinaBob here: -well obviously nobody thought much of my initial notion about how to achieve "faster-steering" in a C3, so put away that hacksaw, ---I've indeed run across a much better solution which can net you a substantially more responsive steering action. Although I am not recommending this outfit (know nothing about them, -and there are likely sources less costly), --but a company that actually offers a reduction from the C3's sluggish estimated 17:1/Steering-ratio down to 12:1 is at:
www.flamingriver.com , and they offer both a bolt-on exact-copy (external appearance) retrofit/Steering-box iteration for $400, as well as a gearhead's retrofit-kit option (which should be half that figure, --but is $300); ---you can call'em: 800/648-8022 for additional info.. Nowthen, would like to hear from anyone having experience with this nifty C3 item; ---or perhaps know where one can obtain a quality "fast-steer"-kit for le$$. Please advise...
