checking out rotors for a future brake job, and well since iam a noob to the BMW world, i was wondering what rotors are the best out thier for $$. this is a street car and will not ever see any track, but it is driven hard. i wont mostly longevity, than performance.
was looking at BMP's its and came across the power rotor, like the slot design and teh price. but its only availabie for the front. i would like a matching set for the front and rear.
you should definately get the slotted only. The cross drilled are great on the track, but they develop tiny stress cracks between the holes that can lead to catastrophic failure. I know a guy with an M5 who had brembo cross drilled rotors on his car and while he was on the track on day the stress cracks caused the rotor to dissinigrate all at once, destroying his fender and wheel and causiing him to spin out.
BMP has some good rotors. Just don'tt go with stock rotors as they will cost you an arm and a leg and will still not be as good for hard driving as the aftermarket ones.
exactally the opposite. you're not nearly as hard on rotors on the street like you are at the track. how many times have you heard of a street only car with exploding x drilled rotors? how many times have you heard of a track car with exploding rotors? this is why most shops will recomend x drilled only for street, and slotted and/or dimpled rotors for track use.
i use slotted and drilled rotors on my eclipse in the front and back, for the bimmer i will be getting zimmerman rotors for now.
I use Brendi and I buy them at BAP-GEON for about $23.00 each. These rotors are not cross drilled (ever see cross drilled on a NASCAR machine, and even the PORSCHE cup guys take of their cross drilled at the track). More surface area and better cooling are what you want.
Oh, I drive a 1988 750il and she is a heavy machine.
Well i can think of two kits off the top of my head, bmp has one i think and Ireland Engineering/SEAM has a big brake kit. But if your on the road use slotted they have to be the best in wear and stopping that you can get. And in my opinion cross drilled are good for looks but when you want to get some stopping power slotted is the way to go no matter if you only have them for the front they will still perform about 4x better than stock rotors all around. Just my two cents
LOL , Bmwdubya, we dont need another SEAM promoter. They are cool but still the forums already has a SEAM promoter. HUM who could that be????LOL No offense to anyone. :P
haha hey guys lol yes we need more :P go seam umm im looking at getting some new rotors also some1 said something about 24$ rotors that are really good...umm let me in :-D
