I need new shoes, so i'm thinking about torch red powder coated rotor hats on new drilled/slotted rotors. I've seen them on cars at shows, but does anyone know how well they hold up to the heat generated by braking hard from racing? If so, who makes the best?

Those rotors are for street/show only, if you go racing take them off and use stock. The holes will form cracks.

Wolf Dog

He's absolutely right!

The only reason why i wanted the powder coated is that i painted my rotor hats with hi temp caliper paint, but the fronts keep fading. I wonder if anyone sells the "solid" rotors powder coated on the hats?

For street use powdercoating the hat area will work fine. And as other's have said the vast majority of slotted/drilled rotor's are for show. I know I have the Baer Enhanced rotors and would never consider tracking them. But they sure do look purdy out on the street.

I bought a set of brembo blanks from Nate @ corvette garage, and had the hat's powered coated, I drive the car hard and they have held up fine "NO" cracking yet!

Note: "NO" track time just hard driving

D/S rotors are for bling only and 40 year old technology that some ppl wont let die just so they can make a buck.

racing or DE Brake temps can get as high as 1400* which will burn off any paint or powder coating.
Now some ppl have two sets of pads and rotors. one set of D/S rotors and pads for the street and shows and another set of plain face rotors and race pads for track time. Best of both worlds.

1400* rotor notice the nice orange glow of the front rotor


a few cracked rotors from minimal track time

Thanks everyone, I think i'll just keep em like i got em now. Too lazy to change just for the "look". I do drive pretty hard on the street at times, plus my pads are polymatrix.

Thanks for the pics, nice shots. Glowing rotors way too cool. I was watching American LaMamns when a c5r's rotor just exploded.

Good info here. I've been struggling with the brake question (I'm due for new brakes any time now) and had been hooked by the D/S mis-information. Now to find a decent set of brakes that will live up to hard driving and racing, yet perform decent on the street. Looks are fine and all, but I'd rather have brakes that stop good than look good.

I've got the powder coated rotor hat covers on my car. You can always remove them when going to the track. I got mine from ECKLER'S

Well, now that GM has joined the marketing bandwagon and started making D/S rotors it will be hard to disprove the theory of don't track them. Especially now that they are on the '06 Z06 as well. The Z06 rotors are bigger and can likely take a bit more abuse before dieing off, but until we get a few owners on here that track them, only time will tell.

Another thing to consider is that drilling is causing the cracks, there are brands available that have the chamfered holes without drilling so the possiblility of cracks are lessened. I'd want a written guarantee against cracking and they ain't gonna do that.

Z06 Brakes
--------------------------------------------------------------------------------

Corvette Z06 employs monoblock six-piston front calipers and four-piston rear calipers. Each piston utilizes its own pad. The opposing pistons operate in pairs, applying brake pressure equally to each side of the rotor. The extra-large 14-inch front rotors and 13.4-inch rears are vented and cross-drilled. Brake cooling ducts are capable of moving three times the amount of cooling air compared to the previous-generation Z06.

Camfered holes or not, ( first pic has camberd holes above) and this

The new 6 pistion BPR caliper on the new ZO6 will help. The rotors are 1.4" think not like our 1.25" thick rotors on the C5 and C6 will help, but they will crack

This BIG Porcsche GT3 Grand AM race car's 1.4" thick d/s with camferd holes rotor cracked after 4 hours of track / race use


The mechanic with car, which was parked next to mine said they change rotors every 4-5 hour of use. And the funny part during a warm up session he and I were running together, i.e I was fallowing him and he could not shake me. I could always out brake him, go much deeper iinto the braking zone then he could. and out acccelerate him.

Air does not really move though the holes to make a difference. As soon as you start to use the brakes those little holes fill up with brake dust. No air movement.

Drilled and SLotted holes are for marketing only guys, dont be foolled by some companies "Press releases" or Marketing BS. Come to the track and see for your self.

I use Raybestos rotors from NAPA $26 each, WIlwood H race pads, Castrol SRF brake fluid, Goodridge SS lines with banjo fittings and DRM cooling ducts all on the stock PBR corvette caliper and can stop faster and in a shorter distance with less fade then most BBKs.

I would he happy to use a BBK but I wont pay for it untill I use it first and it works better and lasts longer then the stock Corvette Brake.

I will look into the 6-pistion PBR caliper when it becomes availbe.

Rotors crack, that's just what they do, you can buy them for $25 or $300, take your pick.

Have done with high temp paint and powder coat. It is fine for the street but if you do track events forget it.
