Just bought a Hotchkis STB for the LS1 to fit on my SS. We were trying to put it on when the damned thing would not match up at all.....Come to find out(right before we were going to give up) that the brackets have a different mounting pattern. I was like well damn, so we put it on the right way and it was pretty snug, but fit. After driving the car with it on, all I have to say is damn, the car feels much more responsive and tight. I paid $150 for it, which I guess is a good deal, I mean I bought it from my friend. The red color compliments my red car and engine bay very well. I am glad I bought it
