This is educating; but, I must ask the question - why does the SRT6 have a fixed spoiler? I can't imagine there is much lift at slow speeds so why not just use the original spoiler?

(By the way, for you young squirts, if you want to see a car with lift, you should try a '59 Chevrolet at 100mph! Now that car was not made for those with faint heart. If you hit a crosswind at that speed, the son-of-a-b***h wanted to crab into the wind! Ah, the good old days! I will take the good new days any time when it comes to cars.)
