you will have firmer ride, and road noise on those concrete stretches of road as well. Tires may help, but it is the nature of the roadster, and over time, you will forget about it. My coupe is much quieter, but rides about the same. Enjoy it.....as she is a rare bird.... Everything you need to know about repairs and parts is right here. You just have to do a little searching or just ask....but, keep in mind, during all that help, you will get more than one opinion, but one will be right somewhere in there....lol
