Mrbig · 07-27-2013, 09:53 AM

What can we use that's better than stock with stock caliper ?

Mrbig · 07-30-2013, 09:28 PM

Front only.

I've found some cool looking rear floating rotors from REBS in Korea. Will pass on the pricing when I find out.

Anyone running the race brake rotors any good ???

the second set is interesting, wonder why they don't have a front set

This is what I'd go for (due to good feedback from other platform):

I found these prices to be pretty good for OEM rotors.

As OEM(likely German made), those are good prices, but keep in mind that OEM isn't genuine BMW.

NOOO used them (not on M3), horrific quality hit or miss. Can't speak about their BBKs

@ the OP. The OEM rotors are solid. You can pair them up with more agressive pads at the expense of rotor life, of course

RacingBrakes were an excellent upgrade that i used in place of the stock & DBA 5000 series rotors that warped on a 335i.

RB rotors are a good upgrade for a street car, but they have not fair well on the track. If 2-piece rotors are a must-have, the PFC DD 2-piece is a much better choice.

Mrbig · 10-16-2013, 01:31 AM

Rb rotors ? Best idea ? ?

pbonsalb · 10-16-2013, 06:38 AM

When you write "better than stock," what are your expectations? These are just lumps of metal that absorb heat. The stock ones do a very good job. The quality aftermarket stock replacements will also do a very good job. Low quality aftermarket replacements may warp, crack, or fill their vents with rust faster. Expensive aftermarket upgrade rotors may weigh slightly less if two-piece and/or vent slightly better, but I am not sure even a race car driver could tell the very slight difference. For some two-piece, there may not even be any long term cost savings since replacement rotor rings are proprietary and possibly as expensive as new stock or aftermarket stock rotors.

If you have a problem you are trying to fix, the it is worthwhile looking for a solution. For example, maybe you are warping stock rotors regularly on the track.

I noticed the OP's other thread on lightweight batteries. If paying big bucks to save a few pounds is important, go for two piece rotors. You should drop a couple of pounds per rotor. This is unsprung weight, so savings here are worth several times that elsewhere. You could probably also save some weight with a full aftermarket brake kit that replaces the massive cast iron single piston sliding calipers we have. Just don't go much bigger on the rotor or you will offset the loss. Lightweight wheels are also great, and some tires are lighter for the same size than others.

In your opinion, what would be the way to get more initial bite without breaking the bank? Is BBK the only way to go?

I did the mistake of driving a new 911 in the mountains.

initial bite is a function of many variables. You can get different initial bite by just changing the pads...

BBK is more for heat management...

pbonsalb · 10-20-2013, 03:15 PM

For the most initial bite, I'd stick with stock brake pads. Bite is really in the pad material. Most performance pads shift the temperature range up, so they trade initial bite for more fade resistance under temperature when worked hard.

I don't think big brakes stop any better in daily driving on the street. Their advantages start to show up when their better heat dissipation comes into play, which is when they are hot, like during repeated high speed stops. Unless you drive at high speeds on deserted canyon or mountain roads, you probably won't experience fade unless on the track.
