I have just purchased a 78' and I am replacing the the rotors. Can anyone suggest a decent rotor to go with for around $80.00? Is there any difference from the stock rotor or a slotted rotor?

OEM-style rotors for $60. Also check the top of the forum as I believe there's a discount code for forum members.

Slotted rotors will definitely give more braking power as the slots bite into pads. Whether that's worth it for how you use the car is for you to decide. For normal street driving my opinion would be OEM-style work just fine. If you're doing some track racing or auto-crossing then you should consider slotted.

 

I would like to stop on a dime,..... that way I can pick it up and put it in the car fund. Napa sells slotted http://www.napaonline.com/cgi-bin/nc...rpid=105278567) for $66.00 I just don't know if there any good. Thank you

 

I would just go with plain solid rotors. I've seen small cracks develop in the holes of drilled rotors on a racing Porsche. If you really need fancy rotors, go with slotted. The purpose of the slots and holes is to evacuate gas that builds up due to very hot brakes. Unless you are on the track, I don't believe your Corvette brakes would see this kind of heat.

 

A good (American made) stock replacement rotor sells for $59.95 ea. VBP # 11703 (fronts) and 11704 (rears).

Depending on what you want to do with your car, slotted and / or thermally treated rotors can be a serious improvement but also cost a lot more.

The slots we machine run against the angle of the fins inside the rotor so they do not weaken the rotor. Additionally, the slots have a unique double ball milled leading edge so that they pull and release much more gas and dust / debris away from the brakes than plain or 'fancy curved' slots.

The thermal treating we do is a series of freezing (below 300 degrees F with liquid nitrogen) and heating (400-plus degrees F). The number of cycles and exact temps are a trade secret. But the end result is the metal becomes much more durable and the density actually increases. These rotors last more than 3 times longer than a stock rotor. This process has been used by NASA, the military and other high end users for a long time so I suppose it is good enough for our Corvettes .


I personally do not recommend cross drilled rotors only because of all the feedback I have heard over the years - more bad news that good it seems.

Depending on how you plan to drive the car, we could suggest any combination of pads / rotors / fluid / hoses, etc. Hope this helps.
