Front Disc Rotors

bigwave2255 · #1 08-09-2010, 05:49 PM

hi

just wondering if the 3.0i / 4.4i front rotors are the same as the 3.0d (E53 2005)

i have a warped rotor (s) and the spare parts store i go to has a listing for the petrol engine cars but not the diesel.

also how hard are they to change???

i guess just remove the caliper, swing it out of the way, and remove a retaining screw (or two) and they fall off, have i missed anything??

i thought i would get some cross drilled rotors??

any thoughts

they DONT just fall off (like the BMW manual says), they will be stuck and you will have to pound them off-well at least thats how I got mine off

i checked in the how to,s and found a good write up, only question now is are the rotors the same across the 3.0i, 4.4i and 3.0d e53 cars, apparently there is a separate listing for the 4.6i, and are cross drilled rotors any value, i know slotted are not as all they do is wear your pads out earlier,

No. If you are not going with a big brake kit, cross drilled replacement rotors are just for show. Replacing a stock, plain rotor with one the same size that is drilled is a waste of time. All drilling does in this case is take away some of the metal that dissipates heat, which means it is a downgrade, not an upgrde. Plus, they have been known to crack around the holes.

The information I have says that the 2005 E53 3.0d has the same brake rotors as 3.0i.

If it were my X I'd bite the bullet and buy OEM.

You right! it's even impossible to fall off, however I did mine today and they were kind of weld to the metal 2gether, and you have to hit them hard with harmer to come out. When I drive at 30 to up and I apply brake, my steering wheel used to shake side to side so bad. But after replacing the two front rotors
The shaking steering wheel while brake applied is all gone!!! I have a smoother stopping reaction when braking now.
