ACDelco performance rotors?

[ehoff121]

I found DuraStop performance rotors available for the Vibe on the ACDelco parts site:http://198.208.187.182/interne...A1573Anyone ever used them? Would you use them? They seem to cost between $75 - $100 each online.

Completely un-nessassary on a Vibe, unless you are after the "look" In fact, by adding the slots and drilled holes, you are decreasing the surface area of the rotor... The slots help keep the pad clean and the holes help evacuate the gases produced during hard braking... But on a vibe with not much in terms of overall "performance" it's really not needed.. you would be far better off, buying a good set of pads, unless again, you are after the "look"

I have to disagree with you a little dude.I upgraded my brakes a month ago,and went with drilled and slotted rotors.Big difference over stock,since having the s/c the vibe was really hard to stop.Now I'm at ease knowing my wife can feel safe.I did upgrade the pads also,but well worth it in my opinion.

Unless you added a hefty amount of weight with the car with the SC (which you added some, but not a lot) the only difference would be braking from "high" speed, do you spend a lot of time comming down from over 100mph? I didn't think so... so nothing really changed... Like I stated above, the slots/crossdrill does provide "some" benifit(pad cleaning and gas evacuation), but at the cost of losing some surface area, and braking performance, which you made up for with better pads.. If you changed them both at the same time, you can't tell me you noticed a difference in the rotors... now, if you put the pads on first, noticed an improvement THEN put the rotors on and noticed MORE improvement, then I would have to eat my words... In the end, the whole crossdrill/slot thing is eye-candy for most... STi's come without either and thier brakes are much better than those of the Vibe (along with the performance factor)... The EVO on the otherhand DOES come with crossdrilled rotors..

I guess you don't know me very well You are right in some regards,but your comparisons are with vehicles with 4 wheel disks.The vibe has crappy rear drums,the difference was huge,and can't be contributed to just the pads.My last set of pads were the EBC green stuffs,and the difference wasn't as noticeable.

And just because the "greens" didn't do you that well, doesn't mean that the new pads would be the same... You are kinda making apples to oranges comparisons.. think about it, taking away your personal feelings towards it... now am I still off base? I also have to ask, did you do a proper bedding/seasoning of the pads/rotors? It's possible that you could get even more out of them, if you "didn't"

I have a set of crossed drilled and slotted rotors on my 03....and will (if $) allows will never go back to a regular rotor ever again.I do not race my vibe or even run it hard but the over all stopping power is awesome.As far as saying its over kill to have them on, I say thats crazy.....its like y would a car company put ABS on a car...how often do u really use it....but it saves lives when u do...well slotted/drilled work even better to stop a car,and should be on every make and model.They are just a great safety device.And worth every penny u pay for them.My 2 cents.

I'm not trying to be a jerk here, but when you got the rotors, did you get pads at the same time? Again, you benefit from the gas evacuation you get from the slots/drill, but once again, you lose out on an amount of swept area of the rotor.. If they weren't oversized, you simply can't have more stopping power.. Now, if you got new pads at the same time... same answer as I gave to Kevera..

Now,I hear ya mang,I'm not a noob to wrenching cars and bikes.I know how brakes work.But my problem before was brake fade.I don't know if it's because of the small rotors heating up too quickly or what.And now the heat dissipates quicker and now I get a better bite,but I did notice a difference.Pads were a factor for sure,and I know I did reduce the swept surface,that's a given.

The main reason they work so good is that the heat and the gas between the pads and rotora is able to escape...thus allowing for much more clamping power..a much tighter squeeze on the rotor from the pads..thats y it grabs so tight.thats y performance cars like the zo6 come with them stock...but ALL cars should have them/...its just a better and safer option.

I know your not a noob to wrenching... wasn't even trying to imply it..lol... but "some" can turn a wrench for YEARS and not truely understand what they are doing... lol... (again, not saying that is you.. )

My 2 cents:On my 2000 GMC full size 4WD truck, I did replace the rotors with slotted rotors and the pads with ceramic pads...what a difference! I know the 1/2 ton truck weighs a LOT more than the Vibe but it still made a huge difference. When my rotors and pads are due, I am going to use the slotted and maybe drilled rotors along with the ceramic pads. A very good upgrade IMO. I just wish I had stock 17" wheels then I would get the big brake kit from SSBC (where I got my rotors for my truck). But there is a reason that the high performance cars out there come stock with the slotted/drilled rotors (better stopping response and brake performance). Why not get a little benefit from all those high end sports cars and go with the slotted/drilled rotors? Just my 2 cents...

[Kamikaze]

Personally I can't justify spending the extra $$ for slotted/drilled rotors.. but I will purchase ceramic pads.IF i were autox'ng the vibe.. then I would definitely consider going to at least a drilled rotor to dissipate the heat, but for my normal driving I wouldn't do the brakes justice.

I cant figure out y car companies will not offer these as OEM....I just find it funny that they will rush out and put fart pipes on there cars a sweet rubber and rims for handling but never think about when they are useing all that new go fast stuff...how about when i need to stop before i hit that kid that just ran out in front of my ride.once again that is just my 2 cents.

You are MUCH more likely to develope cracks on the rotors emenating from the drilled holes... My Subaru's crossdrilled (the old one) developed cracks late in thier life.. This is another reason why the crossdrilled rotors should be left to the high end FAST cars... Slotted rotors are less prone to cracks.. but still can...

[Vibe_dude]

How long did u have them on the car before they cracked?Most ppl replace OEM rotors every 3 years or so,just because they are warpped so bad or getting to thin.I have had mine on now for well over a year and i can say that they have saved my life at least once.And i live on the east coast with really bad winters and last year with all the snow and salt,so far has not in the least effeted performance,and still look pretty much new.Maybe someday in a few more years maybe they will start to go and crack,but by then I will put another set on.Like I have said if I have the $,I will always put crossed/drilled rotors on my cars.Once again my 2 cents.lol

Where the brakes make a big difference is on repeated stops when they heat up and can become less effective. Important on the track, but not generally a factor in normal driving. I'd rather have the durability of regular rotors.

I believe it was partly due to them being well made to begin with, they were KVR, and second, me doing the proper bedding and seasoning procedure on the brakes when i put them on... They still cracked though.. They never came apart or anything.. If i went with a big brake kit or something, I would consider them again, the change in rotor size would account for the loss in swept area, otherwise, I just don't see the need, even with my Subie.. Good pads, that's a different story...
