Unless you are racing or maybe you need to have calipers which are bigger and more colorful to give your car a badder look, the stock brakes on a ZR-1 are pretty darn good.

If you need an upgrade but are looking for a bolt-on, high-bang-for-the-buck modification, I'd try a slightly more aggressive brake pad, one of those aftermarket front air dams with brake ducts along with a fluid flush.
