i have an opportunity to buy a full set of c6 z51 rotors..will they fit on my c5 vert?
Used?
New ones are fairly cheap.
And, as stated, front wheel clearance can be an issue, stock C5 wheels won't clear, and you would need the matching caliper brackets.
Simple upgrade for more stopping power, if you really need it.
Their contribution is less fade from repeated braking, like auto-cross for example. Not likely to stop faster than stock for typical street use, but they do look cool.
GM does not make the brackets any longer, but they are available aftermarket. You can use stock C5 calipers or C6 calipers. If you want to go all out C6 Z51, the rear calipers are unique, having a 42.5mm piston. I’ve been told that the stock C5 rear calipers are an acceptable substitute.
DBA makes some pretty nice rotors for a decent price, I used them when I did the J55 brakes on my 2000. Picked up a complete set of calipers and brackets from flea bay, rebuilt the calipers with DRM stainless pistons and seal kits along with steel flex lines. Night and day difference between stock C5 brakes, I find it takes much less pedal effort stopping then previously.
Here are some notes from when I installed the C6 Z51 front brakes on my '99 FRC. I went with the DBA 5000 2-pcs rotors to help offset some of the weight gain that came with a larger diameter rotor along and the beefier / slightly less prone to spreading C6 2-piston calipers with DRM stainless steel pistons.
