Does anyone here have Slotted/drilled irotors on their Bonneville? If so how are they and are they any good? I have them on my Intrepid for 3 years now with no issues at all, but i just wanted to know how they did on our bonnevilles... Im getting new tires soon and the rotors are rusted pretty good along the top (round edge on the outside of rotor with the "Teeth") from the car being up north the first 50k of it's life!! and im going to go with the Cmax pads from autozone!!!

and before anyone ask or comment on the search button i did that and not 1 item came up!!!
Thanks in advance guys/gals

Stay away from drilled. Most shops won't turn them, and they decrease braking surface area. The holes are critical, if they aren't cast into the blanks, but drilled later, they weaken the rotors.

Go slotted. Far safer and more effective. We don't have race cars, and drilled rotors are of no benefit.

A good quality high performance set of Delco slotted and drilled rotors are fine.
Those have painted fins and hub but if you can find some plated units, they are better.

They'll wear out long before they crack and you should never turn our rotors anyways. They are throw away when worn.

Check Rock Auto for some decent pricing.

I am running Power Slot rotors and Hawk ceramic pads on mine and I am real satisfied with those. No dust and excellent stopping.

Look at your budget first and see what is out there, many run the Napa premium line and are satisfied also. It is going to come down to what you want to spend. Just DO NOT go the bargain basic route or you will have all sorts of issues like warped rotors or fast pad wear.

Hummm... Never thought about it that way!!! Thanks and i will consider your opinion!!! My intrepid has drilled and slotted b/c i got them for free from a good friend that had them on his intrepid for a couple of months and ended up getting a new car and took the rotors off and replaced with OE and gave the car to his aunt... And i just like the look of them! I didn't see just slotted rotors for the bonneville on irotors though! Maybe i'll call them to check! But yea i def want to be safe!! Thanks for the quick reply too!!

Thanks for the quick reply!!! Yea i checked out rock auto and they don't have a pic and they want $75 for each rotor! Ill check out those delco rotors also!!!

Thanks for the quick reply!

Yea i know about cheap rotors from all of the stories i've heard from other people and different websites!!! My budget is pretty much what i want, but im not trying to break the bank on it either!! Some people would see a full set of slotted/drilled rotors and Ceramic pads with a $75 back coupon on ebay all for $150 and get them.. lol Then when the car is in the body shop or they looking at a insurance check they asking what happened!! I could just get the premium rotors and be cool with it, but for the same price i can get a good set of slotted/drilled/ or just slotted rotors!!! Thanks for the quick reply!!

is your power slots made by "Centric"? and does it have the vent on the inside like the OE rotor has? I found some for $76 each!!

Um, if you think $75 for a rotor is a lot don't even look at EBC's. They're like $150 each. My NAPA Premium rotors were $60 each, ultra premiums were $90, but nowhere in southern MN had them at the time...

Yes mine were Centric and the fronts have the directional vanes, but the rear are solid.

My EBC slotted rotors were $160 shipped for 2. Worth the price, they're markedly thicker/heavier than the Ebay drilled/slotted rotors on my car before. More meat = more resistance to warping and a longer service life. (I hope!)

Paired with the AutoZone Duralast Gold Cmax ceramic pads and properly adjusted rear drums, my car stops very quickly. And it'll do it over and over again.

Get the EBC's shipped, then stop at AutoZone for the Cmax ceramic pads. You won't be wanting for more brakes with that combination.

Front rotors are $297.95 for the pair of EBC Ultimax rotors: http://www.autoanything.com/brakes/61A3 ... 61390.aspx

i have drilled and slotted rotors on my Bonny. have had them on for 3 yrs now and i did get them off ebay. then got ceramic pads from autzone. im actually due for brakes soon. this spring i will be getting EBC just drilled rotors. i dont like the slots. the brake dust collects in the slots and fills them up, unless the slott extends all the way to the edge. and ceramic iss cleaner and quieter but they dont stop as good as other friction material. thats the trade off

Um, I'm not sure where you're getting that from that ceramic doesn't stop better. Ceramic stops WAY better than the stock semi-metallic pads on my dad's GXP, and the Kevlar/Ceramic EBC Red Stuff pads on my SSEi haul it down way better than stock.

EBC doesn't make drilled rotors for our cars at all. They have dimpled and slotted (sport) or slotted (Ultimax). Also, the slots on their sport rotors do go all the way to the edge. http://www.autoanything.com/brakes/61A3 ... 51502.aspx

I have had my drilled and slotted from rotorwork (used to be on ebay) for several years now with no issues other then the brake pads they sent were crap, I now have wagner ceramics and they are MUCH better

humm... Some good feed back from everyone!!!! Def appreciate it guys!! I really don't know which to order, but i just may end up getting the OEM rotor from Napa if i can't decided which i want to get... but either way im def getting the Cmax pads from autozone!!!

ceramic pads DO NOT stop better then semi-metallic. they have many advantages that make ppl think they do. the advantages of ceramic r less noise, longer life, less brake dust and heat characteristics.

- ceramic is harder material which makes them last longer, with less brake dust, changes the noise frequency to a higher level out of our hearing range(quieter), and they transferr heat better. the harder material also makes for a much harder brake pedal feel. and the better heat transferr makes them not get spongy feeling when hot after heavy breaking.


y do u think that semi-metallic eats rotors faster and have more brake dust. because more friction is taking place which leads to better stopping. they get hotter faster, make slightly more noise, and more brake dust BECAUSE they r stopping better


i do like ceramic better. dont get me wrong. they save on cleaning my wheels all the time, last longer, and yes have a better feel. but if i were to go to a track and do a slalom test done(60mph-0mph). i dont think i will save on braking distance with ceramic.

ive had yrs of testing diff types of brakes on each of my cars. ur going by a feel of the pedal and pants. like i said, the advantages lead u to feel they r better. if u want, test it out, and prove me wrong.

oh and btw, i have the same tires as u. i just put them on a couple weeks ago along with new rear air shocks, front stab links and wheel bearing. but i got the W rated ones. H rating is for stock, something like 130mph.

The primary advantages I've experienced with ceramics are:

1. Less brake fade (almost none) with super-hot brakes. Traditional pads can't compete.
2. Less dust by a wide margin.
3. Longer pad life.

Disadvantages:

1. More prone to warp even high-quality rotors.
2. Wear rotors out to the point of replacement rather than simply turning them for another life.

I def agree... Same review i would give to the Cmax pads on my intrepid.... Thanks

Best brake setup I had on my 1993 (3 versions when I owned it) was Ceramic pads + Napa gold rotors. Low dust, best feel, and less fade than any semi-metallic I used. I was only using store counter parts, but nonetheless.

Ceramics did need a couple stops to warm up however, initial bite was lacking the first few uses when cold.
