I recently scored a great deal on Koni adjustable dampers to go with my Swift springs (which I am overall impressed with), so I went that route instead of starting over with a coilover set-up. Getting your suspension dialed in with as many adjustable suspension parts that you can afford will only aid in finding that sweet spot between driveability and comfort.

The tires that you choose play a huge part in that equation. I'm having to purchase new shoes for my Z since the Bridgestones are several years old now. I initially considered going with an all-season tire since I'm moving to an area back East that experiences light snow in the winter. I will probably instead go with an affordable UHP summer tire like the Firehawk Indy 500. Based on my own research, it seems to be a good all-around tire, even in cold weather. They likely don't do well even with a smidgen of ice and snow on the pavement, but I now have an incentive to buy something AWD before next winter.

That's my $.02 worth, since I had failed to provide anything of value to this discussion beforehand.
