I've gotten 2 different answers from Wilwood. First time I called, it said that their kits changes the track width by adding an entire INCH to BOTH sides. Now I call, and I talk to another guy, and he says it changes it by adding 3/4" to both sides. I asked him if he was sure, and he said, "yes," but I'm still a little weary. Does anyone on here have the Wilwood kit and if so, can you tell me how much it changed your track width?
