You've already got one of the most comfortable summer tires. What's wrong with them?
Are you thinking of switching to the new Firehawk AS? I've seen them reviewed as less comfortable than the Indy 500.
Every tire is going to be different I don't think you can make a blanket statement that all season tires are more comfortable than summer tires. Going to depend on the tire.
Maybe look into reviews for "luxury" "touring" tires and compare them to the indy 500.

Then if these are one of the most comfortable tires I will stay with them. I have lowered the pressure to 32 psi. When I'm on I-89 and I hit those expansion joints on the bridges the car really hits them hard, to the point that it skips the car to the side. Maybe this is common with the Z. If so I'll live with it.

Maybe just try plugging tires into the compare function on tire websites. You can see they rate both the summer and all season Michelin tires the same comfort. More comfortable than the indy 500 but not by much.

You and I are in the same boat when it comes to our Z's. Our priorities are a little different than some others here. In my opinion, your choice to go with the coilovers will be the best "bang-for-your-buck" option that will allow you the most flexibility for ride height and comfort. 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. :tup:

Thanks for the incentive to get coilovers. I'm going to order these tomorrow.

Nice! Let us know how they perform after you put them on. Don't forget the adjustable arms if your alignment gets out of sorts. That in itself can ruin the ride quality and handling characteristics of the car if your intent is to keep it on the street.

Will do... I think if I keep it at the same height I should have no alignment problem. If I decide to lower it a bit. SPL adjustable arms will be the way to go.
