Looking ahead to getting my brakes done, and saw these at Way Motor Works.

I've done quite a bit of searching here and haven't found anything on them. Is anyone running these, and if so, what's the verdict?

I'm strictly street -- a lot of city driving, so kinda hard on my brakes -- and would be thinking of getting stainless brake lines and Carbotech Bobcat pads at the same time.

Cost-wise, the M7 rotors look comparable to OEM/Zimmerman/etc....

Way: Any customer feedback so far?

 

I have had a set for about 3 years now, still look new, no discoloration of the metal at all I have done a couple autox, seem to work well. I have SS lines as well, and am running Hawk HPS pads.

 

I've sold a few sets and never had any complaints. I personally pass on drilled and slotted.

 

Thanks, Way. Any particular reason why?

 

Drilled rotors have a tendency to crack under hard use.
Take a look at the Brembo "Sport Slotted Rotors" at The Tire Rack.

Less of an issue for a car that's not tracked/auto-x'd, I presume?

 

IMHO the drilled rotors are nothing more than bling for behind the wheels. I would not have them on my car. Broken rotors are very scary.

For your use, street driving I'd recommend either slotted or plain rotors.

Just my .02 here.

 

Like I said, I have done 2 autox and no problems. Have done some mild canyon driving also, no problem. Yes, if you are going to track or many autox, I would not recommend drilled rotors. They do look cool though Just for kicks check this out: www.caranddriver.com/news/car/09q3/2010_porsc... these are off a 2010 Porsche GT3

 

Hmm.... How about ATE PremiumOne's, then?

 

ATE's are pretty looking....(seems functional too!!) but the big debate is that slots and holes lighten the rotors, reducing thermal mass, reducing the maximum effectiveness of your brakes before they overheat....and drilled ones have a tendency to get stress fractures....look into Cryo treated rotors? Not as blinngy...but functional....depending on who you talk too. Some people love them, some say they are a waste of money. Centric rotors can be cryo'd for a small upcharge...cheaper than the "frozen" rotors....Talked to LMG...he installs mostly Centrics these days.....I Put Zimermans on the rears on my car, no complaints.

 

Because no rotor change is going to truly change the rotors functionality your fine with whatever model you choose; slots, holes, both, etc etc. More importantly will be pad selection for the intended use. Picking a high performance competition pad for a daily driver will be a bad decision as would a mild street pad you expect to run on an open track day. Like Way and others have pointed out however a drilled rotor will not be as durable for the long haul on a hard use car.

 

One more thing to add....Noise can be a factor with some Drilled slotted rotors...pad life too....

 

Thanks as always for the 411!

 

In the past I have had two sets of slotted and drilled rotors which did develop stress cracks .These were only surface cracks but enough to make me want to remove them . The problem seemed to be that they were just drilled with no chamfering of the edges. The sharp edge of the hole was a weak point as far as heat build up and was most likely the cause of the issue. Ours have the proper chamfering and should give trouble free service . As far as brakes go if Todd ( TCE ) says drilled rotors are OK , its good enough for me
