Rotors...Stock or Slotted
Is there any reason that I would have to put slotted rotors on my 86 or will the standard ones work ok? The car is a daily driver ( although it is run hard ) with the occasional drag night. The rotors are about $35 for standard and $100 for slotted.
Thanks

I went with plain old rotors from NAPA nad PFCz pads. My understanding is that in most cases, the drilled and slotted rotors are primarily a cosmetic thing.

Spend your money elsewhere.
You will see ZERO performance advantage by changing to those rotors.
If you insist on slotted rotors, get ac delco Durastop ones... they're $65/rear $78/front on rockauto.com

Look over in the Track/Autocross section. Those guys need the best braking action and they seem to prefer the ones they get from NAPA, I think... Use'm up and throw on a set of new ones. So unless you really want the Bling thing save your money.

I've got the drilled/slotted. Look great as long as they don't get wet because they seem to rust up easy. Garage kept though so that isn't a problem. They don't seem to stop any better and if you just want performance then I would stick with stock. If you have nice see through rims then I'd go with the drilled/slotted due to the looks. They've held up well, I put them on over 2 years ago and they still look and work like new.

I was sold on these slotted and drilled rotors until I checked this forum.
It appears that the only ligitimate reason to install them is for the looks.
In theory they will dissapate heat easier but this should only be a concern if you autocross your vette. However there seems to be a drawback with this as if you use them enough to require the extra cooling they appear top crack much easier than the stock ones.
For the time being I will stick with the stock ones as they offer more surface area and do not overheat under normal driving conditions.
Just my thoughts on the subject.

So how come drilled rotors look better, but drilled tires don't?
Both are a performance disadvantage. I'd like to think that anything that benefits performance looks good, and everything else looks tacky.

If you are driving your stock street vette hard the stock (non-drilled, non-slotted) rotors will crack.
By all means stay away from drilled rotors, they will crack faster than stock rotors.
We run slotted rotors on our autocross '89 big brake car. When I ran stock rotors I would usually go through 2 sets of front rotors per year and at least 3 sets of PFC pads.
I switch to slotted rotors 3 years ago, I just inspected them on Friday, there are still no cracks.
I now go through 1 set of pads per year and it looks like I wil get at least 4 years out of the slotted rotors.
BTW, the slotted rotors were cheaper then stock rotors.
