Swapped out stock rotors yesterday!

These are definitely on my wish list.. They look awesome! Did you see a difference in braking?

I will know for sure tomorrow as I will test them and get them nice and hot. I want to go for a drive in the mountains. I need them seasoned correctly. I feel the difference in using a bit less pedal effort to slow or stop the car and they in theory dissipate heat and gases easier due to the slotting and drilling within the slots. The car definitely stops very well with them. Anything loose inside the car is going to launch as I found out the first day driving home from the shop!

The rears are 6lbs lighter per rotor. All four provide a 16 lb savings, all unsprung.

Thank you for providing the correct specifications. It's also your fault for showing me the link. I'm blaming you for making me buy them!

From everything I have read, you have them installed backwards.

What was your source that you "read" from please? Do you have a link? When these rotors hit the market, that was the first statement people made because of the "backwards" direction of the slots. The cooling vanes inside the rotor are facing the correct way to provide the "sweeping motion" needed to provide cooling of the disc. There are different types of slots with specific designs on the brake rotor dependent on what the goal is. The reason these are facing the opposite direction is for "self cleaning". Here are my sources on different faces and also the vanes and cooling of the disc. When first unboxed the discs are marked left and right on the disc hat. The discs also come with a large orange slip of paper with the same advice to ignore the "normal" method, using the "normal method" of visually following the slots the rotors would then be installed incorrectly due to the cooling vanes inside the disc turning the opposite direction and not "sweeping" the heat out of the disc itself. I await your response.

Can't just "blindly" assume that the direction of the "slots" dictates the direction of rotation . .

My Eradispeeds go the same "way"

The left of the photo is the front of the car (for those who are not familiar with 4th gens . . ) . .

Those look sweet!

$1000? More like $3000+. A complete brake setup from a zr1 vette is $8500 or so for calipers/rotors/pads. I would assume the z28 is running about the same stuff.

That sounds close as I was using the 7500.00 figure from a close friend of mine that works for a Porsche Audi dealership and listening to his stories on ordering and installing new ceramic rotors and related parts.

I am very familiar with carbon ceramic rotors and pads. Here is a MotoGP bike rotor. You think the car stuff is expensive? From Colin Edward's Yamaha Tech 3 motorcycle in the garage at Laguna Seca Ha,ha!

"The Corvette ZR1 was the first American car to be equipped with carbon ceramic brake discs. The braking system consists of 394 mm carbon ceramic front brake discs and Brembo 6-piston monoblock calipers, and 380 mm carbon ceramic rear brake discs with Brembo 4-piston monoblock calipers."

Question: will these fit the ZL1 ?

How do you like you Eradispeeds? Can you help explain the difference between the +, +1 and +2's? Thanks!

The rotors are just fine . . . honestly do not "use" them per say since the car is a fair weather toy. So I cannot vouch for their longevity under hard use.

As for the differences between them . . no clue
