Front rotors warped...
I have the stock rotors on my 96 lt4. Both front rotors are slightly warped not to unusual. I am thinking of replacing them with something after market..I am tired of the break pulse at slow speeds (not abs) While I have the car stored for the winter I am doing all the little things to get it back to snuff. Anyone using aftermarket rotors I would like to hear of your impressions and hopefully get links to the manufacture and parts and prices.

Re: Front rotors warped... (dexion)
Save your $$$ on the aftermarket hype. Most are either OE rotors all prettied up and/or frozen. Or, cheapo China specials all prettied up and frozen. Get air to your front brakes if you have routinely warped them. Have the rotors in question ever been cut before? If so, that will just accellerate the warping the next time.

Re: Front rotors warped... (h rocks)
I bought it like that in feb of 2001. I am usually very kind to breaks and haven't ever warpped any. But that being said they are warped the old owner did it the bastage!. I looked at em and they look thinner than they should be but I don't own anything to check for sure just eyeballed em. My guess is they were turned. (new front breaks..someone did work to them..)
Ok, then how about some ideas on replacements...

Try Jeff Koop (18carfan) at Superior Chevy, he is a great source for discount GM parts to forum members.

Re: Front rotors warped... (dexion)
I good machine shop should be able to turn them properly on a brake lathe (that is if they have some meat left). I used to work in a few shops and if they are not aligned properly on the machine from the start they will be warped right after you receive them back. Vette rotors are hard to turn properly due to the design. If yours are good reuse them. You can buy new rotors, have a goof turn them and have the same problem. And if you walk into an auto parts store and buy new rotors, the counter person will recomend that they turn them, don't do it, put them on right out of the box...

Re: Front rotors warped... (dexion)
Here is what I am running on mine. I had a lot of wapped rotors both 12" and 13" from chevey. I went to these about three years ago and have not even had them turned once. I have changed brake pads twice also. A lot heavier then the stock ones. "http://www.powerslot.com/home.html"

Re: Front rotors warped... (dexion)
We go through 2 sets of front rotors a year in our autocross car, doesn't matter
whether we run GM of aftermarket, several years ago I got smart and picked up
a set from AUTOZONE that are warranted for 2 years, they replace them twice
a year at no cost.
Much cheaper then buying new GM and they do the same job. I tried to have a
set turned, it is not worth the cost, just replace them.
The problem we have is we crack the surface before we warp them.
The same thing with brake pads, we use Performance Friction, we get them from
AUTOZONE also and they are warranted for life.
We also run cooling ducts to the front brakes.
We have had these rotors glowing red and still no warp and they stop just fine.

Re: Front rotors warped... (vettmike)
vettmike,
I run brake ducts, too. How do you have yours routed? Are they aimed at the rotor or the caliper? I think it'd be good to hit the caliper, but it's on the back, and I can't snake the duct back there without it getting in the way of the wheel. Please let me know how yours is set up. Thanks.

Re: Front rotors warped... (DaveFromCleveland)
Dave,
I use 2.5 inch ducts and they run through/between the upper and lower 'A'
arms and point at the caliper. The duct is ty-wraped to the frame members
and the shocks.
The car is in the paint shop right now, when I get it back I will send you
some pictures of how the hoses are routed.
Seems to help some, the rotors still get very hot when we work the car

Re: Front rotors warped... (dexion)
Just to be sure it is your rotors, you might double check your lug nuts to ensure they are properly tightened. Loose ones can cause that wobble. Just my .02

Re: Front rotors warped... (DaveFromCleveland)
Dave, you want the air to be directed towards the center of the rotor vs. the caliper. The curved vanes will draw the air from inside the hot rotor and surrounding area and exit through to the outside of the wheels.

Re: Front rotors warped... (dexion)
I had the same problem when I bought my 90, I had them turned and after a couple of 130-70mph applications they were warped again.
I replaced them with stock 13" rotors and haven't had a problem with them since...
