Well unless you try them then you won't believe what we are saying.


I have had them on my car now for over a year, and they DID make a huge difference. It is a 2003 so the rotors couldn't have been that bad, just OEM.

I find the car actually has way better brake feel, when you hit the brakes, the car stops dead in it'* tracks.

I even tested it. I went from a speed of about 100KM/H ( 60 MPH) to a stop in what felt like 20 feet. Previous to that with the OEM brakes and rotors, ( from the day I bought it BRAND NEW FROM THE LOT) it wasn't even close to that, sure it braked but it just didn't GRAB like these new ones did. I also don't get any rotor warp from heating them up like I used to on the old ones, and no fade what so ever. I remember a couple times where I had them OEM ones pretty warm and went to stop and what do you know, it kinda sat there thought about it then started to slow down. In the same kind of situation with the slotted, there was no pausing to think about it, they just work.


BUT seeing that you know it all then I find it funny that BAER would tell you NOT to use products they sell.


and BTW slotted rotors DO help dissipate the heat and they DO help on street application.

for the record.... 90% of brake rotor warpage is not from overheating..

Did you ever think that you are going to a more heat resistant pad compound and thats the difference in braking.. Try using slotted rotors with stock delcos or other standard semi-metalic pads.. you are changing 2 variables in your "hands on driving experience" how can you place all the inprovement in the hands of the rotors when you also changed the pads, and nonetheless went to a better compound..

How is this an improvement...? the stock rotors are smooth on both sides... also, if your pads are wearing uneven its because of 2 things..
-- inside pad wear: Caliper piston not rectracting properly when letting off brake
--outside pad wear: Caliper slides not functioning properly not allowing caliper assemly to slied away from rotor easilt

EXTREME CIRCUMSTANCES ( last time i knew this wasnt from daily driving )

this got real old real fast, and for the record I spoke to some people that actually know what they are talking about and said that this guy is wrong on a few points, mostly about the slotted rotors.

who did you talk to and what makes them know more than me..? that seems like a rather low blow to put me down as dismissing me as not knowing what im talking about.

Chill on the personal attacks, or this'll be locked down again.

I run RSM hardened/slotted rotors and ceramic pads. The COMBINATION of the two is critical. The harder rotors are required for running ceramic pads, unless you feel like tossing rotors regularly.

Toasted, the 87-99'* have different braking issues than the 2000 and ups. We are severely under-braked for our weight. That means we eat front rotors alot more regularly.

Make sure your lugs are properly torqued, and that your hub face and mating face of the wheel are CLEAN. That will help prevent warping, and will contribute to it even more if you get your brakes hot quite often. I warped two sets of rotors coming down the pass on I-5 into Oregon 2 years in a row. On HOT days on long downhills. With properly cleaned and torqued fronts, and very well-maintained brakes.

Enough improvements were made to the 2000'* that the newer cars aren't likely to see our problems.

My advice is to upgrade any 97-99 (particularly 92-99, which are heavier) to good quality slotted rotors and ceramics.

my argument here is not that slotted rotors do nothing for improvement, they do make a difference, i will admit that... however i dont believe that under any normal daily driving will they be benficial. several people are telling me how much better they are, but also when they upgrade to a slotted rotor they also upgraded to a titanium or ceramic compound pad which is more tolerant to heat. How do people justify telling me how much better the braking is when they also changed the pads.. JR high sciencer taught me that any determination based on a study with two variables cannot be held as a definate answer because you dont know which variable had more results or if it was due to a combination of the two.

My question is
1- Have you personally tried them on YOUR car and driven with them???
2- what makes you a brake expert from taking a course from BAER?




I myself have tried them. I also take offense to someone coming on here telling me and others that it is all in our head and comparing us to getting drunk on coke. I have tried them for myself and I did notice a difference. I also talked to Jim W about HIS slotted rotors and he also agrees that they DID make a difference, And I bet if you ask Will ( admin here) he also can vouch for the fact that the slotted rotors ARE better than stock and DO improve braking.




EDIT: Thank you will for responding, I was psoting when you did, LOL.

Actually Will, I did mention that I had them on my 2003 Malibu, BUT they are the same setup as the GA'* so as you may or may not know, they are not the best setup either. And when I installed the slotted rotors on my Malibu I did not change the pads at that time, I bought them but kept my old pads for the simple reason I wanted to see if there was a difference in just pads or rotors or both.


I noticed it from the first time I hit the pedal ( with the same pads as with the stock rotors) that it grabbed that much better, I let the rotors break in like I was told by RSM, then really tested them HARD. Like I have done with the stock rotors, and let me tell you, it'* a good thing for seatbelts, cause boy they GRABBED hard. It was great, I actually felt confident in the brakes from that point on. Once I had fun playing long enough with the gm pads on the slotted rotors I decided to put the pads I also picked up at RSM and they recommended, and I noticed even better response.


So I can say that YES I tested them as I should have. I only changed the rotors but kept the pads and tried that out.

Then I changed the pads and kept the slotted rotors. I know that is not the cheapest way to do it, having to pay twice to get pads installed, but I had to know for myself.

So I recommend that if anyone wants to upgrade, then you have to do BOTH pads and rotors. Just the pads do help, and just the rotors do help, but the combination of both gives you the best.
