I live in the desert, but have driven about year round on drag radials for about 6 years now...and while I get to enjoy driving on dry roads 90% of the time...I have driven in rain, slushy snow up to an inch, temperatures well below freezing, all conditions I have heard people say OMG you will die, car is impossible to control even in normal driving - and I honestly do not know what the hell those people are talking about. Just this past winter I drove my Redeye in the rain many times at ~40 degrees and snow twice and it was just fine. You do have to baby it around, drive like your grandma who hates fast cars is in the passenger seat. But there is absolutely noting dangerous about it, I have the traction control in sport and track too all the time, if it ever seems really slippery I will turn it full on, but seriously, I would like to know what the people who say it is dangerous are trying to do with their cars in the rain. I grew up in Minnesota but haven't lived there for 20 years, but maybe it's because I learned to drive up there that I feel comfortable driving in compromised road conditions...
I will say daily driving on drag radials is the greatest thing you can do for these cars. No point in adding one performance modification to these if you are on street tires IMO. My car feels clumsy on street tires - on the rear that is of course.
