Has anyone purchased or had installed and driven a Smart Fortwo 451 with KW Variant 1/2 or 3 Coil Overs. I would like some real insight on the experience of Smart's reaction to having these installed vs the stock Smart. So far I have been unable to find Smart owners who have tried these. So it's a hunt these, so far, mythical Unicorns. Again this is a call to actual owners or drivers of these equipped cars. Thanks, I want to give them a shot.
