I have a stock 1990 Z51 that I road race. Both my dad and I drive this car at NCCC time trials. We seem to have a problem with brake fade. With both of us driving it it never really gets a chance to cool down a lot before the next person has to take it out again. Since we have to engine or power mods the stock brakes are plenty for what we are doing, but they get too hot for our liking. Is there an inexpensive alternative?
