Solid vs slotted for pulsation

I have always had an issue with warping the ft rotors although the last time they didn't warp for a year with EBC red and Brembo regular rotors. I probably warped them after replacing a wheel bearing due to a broken ABS wire.

I am going to take this occasion to do the 12" upgrade and am leaning towards slotted rotors because I plan on doing auto cross and hopefully some track time. It makes sense to me that the slotted rotors wouldn't be as prone to warpage then the regular rotors, has anyone noticed this or heard differently? Thank you
 


have you tried rebedding the pads yet?

Normally its just exceeding the heat range for the pad and it picks up the coating laid down on the rotor and moves it elsewhere creating the pulsation.

Also you might want to take off the dust shields and run 12" rotors if heat is a legitimate concern.
 
Taking off the pads, sanding them down a little and doing the whole multiple stop thing? No. I want to upgrade now anyway.
 
Rebed is take 'em up to 60-70 mph then down to 30 at 95% brake force then get back up to 70 and do it again. 4-10 times.

then go for 12" rotors.

But keep in mind, the dust shields are for 11" brakes so they wont be doing much once you upgrade anyways.

what? i dont know how this statement makes sense.

I've seen on some cars when the owner removed the "heat shield" from their brake assemblies that they complained about the rotors getting wet in the rain and losing the initial bite until they dry out. Maybe that wouldn't be an issue on these cars.
 
you do realize that after youre moving for a little while the rotors are so damn hot that water immediately evaporates when it touches them....right?
 
Yoooo CT huh? Where in Ct?

I'll make you an offer. Come on over and we'll go out to try and warp my rotors. From there, decide what you'd like to buy.

F Body with some good rotors/pads is treating me right...It's a year since I installed them. Whatcha say... wanna beat the piss outta a car? :th_laugh-lol3:

Ed (WOTGTP), you in? We'll see if we can make you pass out from the deceleration.
 
I'd suggest you stay away from the 04+ upgrade.

their rotors are heavier than the F body ones.

And the rotors are more difficult to find.

Try centric premiums.

wait so does the front brake originally have dust/heat shields? because i have this problem big time and i hate it. if cruising on the high way while raining i have to keep my distance cuz i have to wait for the discs to dry before the pads can bite.

I've never heard of, or had this problem.
 
Im running 12" drilled and slotted with tq stars, and when raining I have to keep my distance as well. after about 3-5 seconds of firm pressure they will dry out and bite, but its a bit nerve racking at first lol

I found a set of front MC SS calipers and brackets, looks like they are dual piston.

I have experienced the wet rotor issue, especially cruising on the highway in the rain. Brakes haven't been applied for a few miles then granny changes lanes at 40 MPH and there's no bite.
