Does it matter whether my rotors are drilled or not drilled, slotted? I have a '03 and my brakes are due for a over haul. I found some brake rotors but they come with out holes or slotted and its additional $$ to get them slotted and drilled?? What would be the major benefits? thanks

Does it matter whether my rotors are drilled or not drilled, slotted?

if you roadrace or autocross... yes. If it's just a street driven Corvette... no.

I've had drilled/slotted zinc dipped rotors for about 4 years on my 2002. They look great. But since I don't circuit race or autocross - they need not perform/holdup any better than the factory rotors.

They look SICK.

For a street car you can run drilled and slotted rotors all day long... and they look cool as TCR-02 says. They are NOT recommended for any serious racing applications, drilled especially!

Drilled will crack over time, if they were molded with holes less chance of cracking.

Best is slotted only.

Watch out for rotors are directional cooling veins and you could get 4 rotors but they really are for only one side of car.

:iagree:

the ones I purchased have angled vanes; but I was sent a complete set for front-rear, left-right.

If you are going to do anything as far as after market rotors for the track, use ONLY slotted. Slotted rotors clean the glaze off the pads and don't take that much mass away from the rotor so they don't heat up too bad. The guy who had my car before me used aftermarket slotted rotors with race pads (rotor eaters) with the stock calipers for the track. This provided all the braking force you would ever want. He described it like this: if you didn't have your seat belt on you'd go through the windshield. But, if you are not going to track the car, it doesn't really matter. Your best upgrade would be SS lines, race fluid (lasts forever and won't boil) and Z-rated pads. :thumbsup:

Look at the ones that Tom Snitzer has on his RR vette, those are sick and very expensive, but he will be racing all the time.:cheers:

Thanks for the mention. Slotted rotors are the best at shedding heat. The drilled look tremendous but as mentioned above are prone to cracking (micro-cracks develop from the holes). For street bling, drilled is fine, if you intend to RR or HPDE occasionally suggest you stick with slotted.

Good luck.

I have ridden in vettes with just about every type of brake setup and what a huge difference there is from stock to the higher end brakes!:party:

Slotted rotors are normally considered safe for track use.

Drilled/Slotted or just slotted have a trade off over stock flat rotors: while they do offer significantly improved cooling, the surface area of the slots or drilled areas is less area for the pad to grab.

The question is are you mor worried about the brake rotors warping because of heat or are you going to be braking Hard a lot. This is why many die-hard Auto-X cars invest in major brake upgrades including a 6-4 piston caliper/monster rotor setup like on the C6Z.

Unless you track your car though, Drilled slotted or slotted rotors will be fine as long as you get quality parts.
