Brakes questions - TO UPGRADE OR NOT TO UPGRADE?

I was just informed by BMW at my 60,000 mile inspection that all four rotors need to be replaced. They quoted me $912.00 for the complete brake job.

I said thanks, but no thanks!

Considering I am not will to spent a ton of cash on brakes (like a Brembo kit), do you guys recommend any brake upgrades for a 323i sedan.
Are the aftermarket slotted rotors worth the extra money?
Are the standard aftermarket replacement rotors as good as the OEM?
Please provide any aftermarket brand names that you guys recommend for rotors and pads.
.
Any recomendations are appreciated.

I will be replacing the rotors and pads myself in the next couple of weeks.

THANKS

I will go Brembo Cross Drilled rotors with Axxis brake pads. If you track the car, go with slotted rotors.

What is the difference between Slotted Rotors and CrossDrilled Rotors, and what benefits does it yield when combined together?

DO NOT order rotors from Bavarian Autosport!

I made that mistake when they were on special last September.

I received the front pair of rotors within a month...

the rear rotors didn't arrive until FEBRUARY

they refunded part of the money on the rears...

but when I went to install, the front rotors were warped!

sent back the front rotors, called and complained, made a big stink... finally got a refund...

and now, the rear rotors which I installed are rusting, because the rotors aren't even treated or cadmium plated!



bottom line: I'm very happy with my Brembo oem replacement drilled rotors.. I have them in front, and in conjunction with Axxis deluxe dustless brake pads, ATE superblue brake fluid and stainkless steel brake lines, my braking feel is great and performance is really nice, all for way less than a big brake upgrade.

I have a 323ci and just upgraded my brakes to what is on a 330i.
These are the same size as the brakes on an E36 M3 just the rotor is not as thick. Very simple bolt on and the cost of 4 wheels complete with master cylinder was $600.

  • Cross Drilled Rotors are more prone to cracking when used very frequently for long periods of time (tracking). This is why cars that track often use slotted rotors because its more rigid.
  • But if your car is just going to be used for the street, then Cross Drilled Rotors are ok. However you still run a VERY minimal risk of them cracking.
  • Whether you choose Slotted, Cross Drilled, or a combination of the two, your choice would be based on cosmetics and whether or not you track.
  • The "holes" in a rotor are there to cool the rotor down and to get the brake dust out.
  • Larger diameter rotor = more stopping power.
  • Brands: UUC Very Serious Brakes
    Brembo 12.6" & 14"
    Mov' It Porsche 993's
    StopTech
    AP Racing
  • If I had to choose one, I'd get the UUC because they're huge or the Stoptech because they look cool and got the patened vane system (minus the logo on the caliper)

Question for CLYDE

Can you tell me the parts involved for the upgrade to the 328i brakes. Where did you get them. How big of a job was it?

The price seems to good to be true!

Any details would be great.

THANKS

Can anyone really feel the difference between 14in kit (Brembo 14in) and the 12.6in Kit (Also Brembo). If there isn't much difference in stoping distance, why spend more to get teh 14in other than appearance. How much do they run? and who has the best prices?

I recommend getting stoptech or ECIS's kit which uses boxter S calipers...
brembo 12.6" kit is almost not worth the price...
Stoptech lists for $1995, I have some hookups with the NW distributor, let me know if you're interested....

Do you have a pic of the stoptech kit or ECIS kit on a car?

The store here sells the ECIS, but not a great pic. I'm getting some 19in PG3s, so i'm looking to complmnt those with a brake kit upgrade soon. But how soon, i'm not sure. I'll be sure to get a hold of you though!
