I wasn't a believer in the beginning...and really decided to do this on a whim...Rob did it in the parking lot in the dark, he works better in the dark, I work better holding the light...so, next morning, we went up to Harbor's to wash the cars, on the way back, well, I had to play....nice low end now...but need the slicks to hold her now...LOL>>>>>and, a little louder....as well...cops, which I am still one, were terrible up there this yr, just about had to talk my way out of one....LOL
