runt Posted March 30, 2006 Report Posted March 30, 2006 Anyone find any use of having drilled/slotted rotors besides looking cool? I don't Autocross the car, it's just a daily. It needs brakes...pretty badly...and figured that I can find them on Ebay for only a little more than what I'd pay local for normal rotors. Also, if I were to do this, would any type of pad work? I don't have aftermarket wheels on the car (yet) and figure drilled might look cool and even last longer with how fat these cars are and the great stopping ability...ha. Thanks. Quote
19902drlumina Posted March 30, 2006 Report Posted March 30, 2006 i personally dont like slotted rotors ( more for racing aplications) and wear ure pads down so fast so ure spending more money. drilled are ok keeps them cooler so technically last longer (less warpage) but also drilled rotors have a tendancy to crack at the drill holes. look around and look for quality and info. just my oppion david Quote
19Cutlass94 Posted March 31, 2006 Report Posted March 31, 2006 For a daily driver, dont get drilled rotors. They crack around the holes, unless you get the very good kind, which will be so much money you wont want to buy em. Slotted rotors work very well. Most slotted/drilled rotors are good quality and you wont wanna use a shitty pad on them. Id say use a semi-metallic pad with a slotted rotors for the street and youll stop MUCH quicker. Quote
runt Posted March 31, 2006 Author Report Posted March 31, 2006 Distance isn't a problem with this car. My old '96 Cutty...now that thing...jebus...that was BAD even with a fresh brake job. Well, with that said, I'll just pick up some regular ones locally. Maybe I could drill them myself in one of the Milling machines at work. Even put a slight counterbore on the hole, maybe stop it from cracking. Nah, thats too much work...lol Quote
19Cutlass94 Posted March 31, 2006 Report Posted March 31, 2006 Im going to be needed rotors and new pads soon, when I do Im getting slotted rotors, There should really be no reason why they would wear rather fast. Unless you like to ride the brakes or something of the sort Quote
runt Posted April 1, 2006 Author Report Posted April 1, 2006 Huh. Somethings to keep in mind I guess! Quote
GutlessSupreme Posted April 1, 2006 Report Posted April 1, 2006 Drilled rotors only crack when the wholes actually ARE drilled. if they're cast that way to begin with, chances of cracking are slim. Quote
cutlsp Posted April 1, 2006 Report Posted April 1, 2006 Drilled rotors only crack when the wholes actually ARE drilled. if they're cast that way to begin with, chances of cracking are slim. Don't they also cast the slots into some rotors too though? Quote
luminal67 Posted April 3, 2006 Report Posted April 3, 2006 the holes are there to vent the gases produced when the pads get hot. if the gases can't escape, they will form a barrier between the pads and the rotor and decrease your braking force. slotted or dimpled rotors have less of a tendancy to crack. but i havent seen them for our cars.

19Cutlass94 Posted April 3, 2006 Report Posted April 3, 2006 they make em. RSM racing has em, theres another company, cant think of the name that makes em as well. Quote
luminal67 Posted April 3, 2006 Report Posted April 3, 2006 i forgot about RSM. now i wish i had the 400.00 for them. maybe ill buy and install them one at a time Quote

Thats pretty much what I found eBay for mine (same price, etc.) and I guess I'll have to find the auction again and maybe just go slotted b/c I'm sure they would/could crack pretty easily. But at the same time, if the holes were slighly counterbored I wonder if that would help from cracking. Quote
19Cutlass94 Posted April 3, 2006 Report Posted April 3, 2006 I think its powerslot rotors is the other company I was thinking of. RSm is just too expensive in everything they have. Quote
brianhasadd Posted April 4, 2006 Report Posted April 4, 2006 I want to do Slotted rotors on my GP. Do y'all recommend it? or should I just wait til' I need new brakes and just keep the same rotors?? Thanks Quote
runt Posted April 4, 2006 Author Report Posted April 4, 2006 I think maybe I'll just keep my eyes open for something slotted. But I know how i am, I'm gonna get lazy and just put regular 'ol stuff on there anyway...lol Quote

I'm really interested in getting a full set of slotted rotors for a '96+ setup for my TSTE.. that's a few months off still, though. Quote
19Cutlass94 Posted April 4, 2006 Report Posted April 4, 2006 The one company I e-mailed a while back told me prices of like around $300 for 4 slotted rotors. I gotta try to find that website again. Quote
futuretgper Posted April 5, 2006 Report Posted April 5, 2006 the way brake pads and rotors are designed today don't really require drilling/slotting....they used to do it mainly to alow gases to escape from between the pads and rotors (so they didn't ride on the gas).......but now they don't use those compounds much anymore and slotting and crossdrilling are usually unecessary...as for cooling effects.....you want some heat in your rotors and cooling them and heating them too fast can cuase cracking and warping (track conditions) anyway. besides rotors are all builit with internal cooling vains that do the job adequately.....from the things ive read they (drilled/slotted) are more flash than performance. 2c's Quote
