I've been running DSW06 since I had the car. I agree with X.I.r.8. , the reason I went with them were cold mornings. They are obviously not extreme sport tires. Cornering they give a little on the sidewall but then stiffen up and stick really well. Ride will be softer and much , much quieter, but you can push them, you just need to get used to them. I wouldn't track them. They are amazing in rain and snow, I run them on all the cars I've had since the tires came out.,, but the roadster doesn't see salt/snow. One hint is to push the front psi to 40psi or so, transforms steering feedback for the better. I keep the rears at recommended 40psi.
