I respect the SRT-4. It's great for affordable speed, just like the new Cobra in its higher performance and price range. With a little money, they both fly.
With my Blizzaks and Rotas, I recently raced an '04 SRT-4 with tires and everything stock except boost. Even though I ran a 13.1 and he a 13.8, I trapped at 105.4 and he closer to 106. By the way, he was a nice guy too.
Unless the roads are slippery, they have a serious bang-for-the-buck advantage.
