Brake Rotors

Anyone have experience with these?


Getting a little vibration when I brake so think it's time for new rotors.

These seem like a good deal.

Get BMW M3 competition drilled rotors/brake kit. If you don't want to drop $3500 and want eBay brakes instead, then go with Brakemotive drilled/slotted rotors. I have them on my 350z and they are awesome! You can look them up on ebaymotors, a lot of corvette owners use them as well. They're made by Power Stop.

The price is certainly in the 'good deal range' but unless you are going for the sport look - the drilled and slotted rotors are really just for looks these days. The brake pad compounds have changed and evolved to the point that there is not the gas release during braking that the slots/drills were originally designed to relieve... I have also noticed that the drilled rotors seem to be a bit more 'grabby' and are much more prone to cracking compared to a standard 'blank' rotor. Just my .02

The slots were designed for gas escape, but the cross drilling is designed for cooling purposes. By drilling holes through the rotor, more surface area is exposed to the air. With respect to the rest of your post, I agree. Slotted and cross-drilled rotors offer no compelling performance advantage over the stock rotors fitted to our cars, especially for street use, and they do cause greater pad wear and are prone to cracking. If you need new rotors, and like the look (I do), then get a quality set of cross-drilled rotors. Your best bet would be the OE for the European market M3 (or upgrade to the CSL fittings if you want to burn some serious cash, since you will need new calipers to go with them).

Callahan brakes!?!? That's the company in the movie "Tommy Boy"!
Seems like some fiction is involved with those rotors.

I've used Tire Rack many times. They seem to have the least expensive prices. Stick with the good brands like ATE, Brembo and Centric Premiums. Shy away from brands you have never heard of or used, but if you are so inclined to buy/use them, make sure they are local to you so if you need support, at least you know where they are. On the other hand, if you're like a lot of other Fellahs who don't auto-x or do track work, my guess is that they're probably OK for normal road use.

Pulled the trigger and purchased these: http://www.ebay.com/itm/FRONT-Premiu...2f8d52&vxp=mtr

So far so good. No issues. Breaking seems normal/the same.
