I have a front and rear set of Rotorpro drilled/slotted rotors that I would like to get some feedback on. I have heard all kinds of stories about drilled rotors developing stress cracks and breaking. My car is basically a street car with a trip to a nearby road course once or twice a year. I was wondering if any of you that have these have any issues? Please let me know how many miles you have on them too. Thanks~

 

If I remember correctly I could of sworn I read that rotorpros offers to replace your rotors if and when they do crack. I'm getting a set of these for X-Mas.

 

I too would like to get a set in the near future and am curious about issues..one issue I do know about is even the zinc coated ones rust on the inner and outer edges and in the drilled and slotted parts. tom(89trooper) painted his on these sections and it seems to have corrected the problem.

 

I have a friend with some crossdrilled rotors, not sure what brand.. and his are starting to crack.

 

You are a little late to be asking this as it has been mentioned numerous times in the past. I have followed your post for a long time and you seem to be one for doing his own thing regardless of what one says when answering your questions.
Am I corect?

 

How were they being used? Not seeing where strip and street use would cause a problem...road course use is probably a different story...

 

 

Well I am debating weather to even add these rotors and that is why I am asking if anyone has a specific problem with this brand. I appreciate most people's opinion on this board and I guess at the end of the day I do what I want. What's your point? You didn't add anything constructive to my post.

 

I thought the point was clear. Why you even bother to ask.
OK you want something constructive. Sir if you will do a search here on these forums you will be able to locate loads of information on the subject you requested.

 

I haven't heard of any negative experiences with Rotorpros on S197 Mustangs, yet, but I haven't thoroughly searched either. I gather from the wording of your post that you already have them? TacoBill has had them for a while and no problems

There's been a couple of instances of cracked drilled/slotted Rotorpros on Lightnings:

Thanks for the info Daniel!

 

Here are a few Picts!

i like the idea of the black rotor, that is why i am going to go with the granatelli set that are dimpled and slotted instead of drilled and the black stays in the slots and dimples

 

Nice setup, I have these on my Lightning and they have never been an issue.

 

Bill, awesome pic's!! Now are those black Zinc rotors from Rototpro?? I see you have the black chrome bullitt rims. I have been debating whether to get them myself. After looking at your pic's they may have to be added to my x-mas wish list!! ha ha...I am planning on trying to find someone who can coat my Cervinis grills in black chrome over the winter.. wonder how that with matching rims would look. I even have a blk chrm wathc to match. Nice pics man.

 

FYI you can get dimpled rotors from rotorpros. You can get whatever you want from them, just ask and you'll get a quote.

 

Ok here is my question to all of you. I want the granatelli rotors because they are slotted and dimpled and come in that nice black finish, now, would it be better if i went with Rotorpros crossdrilled and slotted in black or stick with my choice for Granatellis? Do Rotorpros have an advantage over the others? How far does Rotorpros warrenty go as far as the drilled holes cracking? Would i be loosing cooling performance if i stick to dimpled and slotted from Rotorpro instead of crossdrilled? Is there a difference between Granatellis rotors and Rotorpros rotors if both are dimpled and slotted?

 

Only thing to be aware of with dimpled rotors is the noise. As the rotors pass through the pads, the gasses escaping from the dimples make a popping sound. Kind of like a card against the spokes of a bycicle. I put EBC slotted/dimpled rotors on my wife's car (Stratus R/T) and it took me a while to figure out what the sound was. Drives me crazy. Can't hear it with the windows up though.

 

Yea it is an amusing sound!!! And thanks for that analogy... I hadn't thought of comparing it to the sound of baseball cards in the spokes of a bike.

 

How many people remember that.....
