It looks like this was an ex_SCCA GT1 car. Depending on how liberal the previous owners interpretation of the rules was, it could have some good stuff under it already. Some of these guys snuck in some tricks from Guldstrand, Greenwood, etc that go well above and beyond what the stock suspension geometry is capable of. I'd be interested in seeing under it.
That said, as with any of these builds, it depends on what you want to do, how much you want to spend and how close you want to be to the pointy end of the field. Vette Brakes is out of business, so don't even bother looking there. Van Steel, Ride Tech, and Detroit Speed are the first three that come to mind....Each with an increase in price for performance.
I researched for over 6 months before I made my decision. I looked at all three options above. I also contacted Mike Maier's people, and several manfacturers of aftermarket chassis which use C5/6/7 components. I'd be happy to share my thoughts and findings via email.
