Car was painted but turned out bad so needs paint. air does work, but never used it. Track times last time it went 3 years ago it ran 12.8 spinning 1st, 2nd and 3rd with bfg drag radials. Since then I put a bigger turbo went from ta 49 to gt6152, and put a powerstroke intercooler on it. Also has MT ET Streets. hooks pretty good on the street. Needs to be tuned. But it will break the tires loose at a 45 roll with stock tires.
