    Why not just do 1st gen CTS-V calipers? They're a direct bolt on!
    I like work. It fascinates me. I can sit and look at it for hours.

    Whats the difference in the calipers and are the rotors larger. Been doing some road race stuff and for sure need better clamping and heat resistance

    I have cts-v calipers. They are not exactly direct bolt on in that there is some things you need for them to bolt on properly but they do directly bolt into the current spindle just fine. You will need 18" wheels or grind the calipers to fit. These are the parts I used:

    8 m12 washers
    4 copper washers
    Custom brake line from flynbye
    Wheel spacers (since my wheel spokes went inward too far)
    Moser wheel studs
    2007 ZO6 14" rotors
    2007 CTS-V brake pads
    1998 Trans Am WS6 - Phantom

    That's what I thought. I want to avoid 18" wheels. Like the 17's I have and want to keep them. How much grinding are we talking about

    Here's some pictures with stock ws6 wheels test fitted. They technically fit but way to close for my comfort. I would think just a minor grind would be good. For me it does not really rub or if it does just so slightly.

    About 3/8-1/2 inch? That's plenty! If your wheels flex so much, you have other issues! Lol

    Pretty cool. I'm excited to do this upgrade. Thank's every one for the input. Fast cars need to be able to stop

    I think a quarter inch at most would be plenty. I would be worried about the calipers stability and strength if grinded more than that.
