Just bought 2004 srt 4. You guys aint kidding, what a great car. Im from Minnesota, and winter is around the corner. Anybody know how the stock tires work on snow? If its pretty bad can you guys let me know what tires to run. I ran scorchers on a 99 dakota rt for 3 years so im pretty familiar with a little bit of slidding. One other thing does any of the mopar performance stage upgrades void warrenties. thanks
