335i Brake Upgrade

I am looking to upgrade my brakes on 335i. Is there a kit where I can use just bigger rotors on same calipers. Have done a search nothing came out.

Any ideas.

I like those but heard they were made in China. If I'm wrong please chime in. I also did hear you could get rear matching ones but I don't see them on their site. I'm planning on going stoptech drilled and slotted. Half the price and made in California. I'm going rotors and cool carbon pads probably because I hate dust instead of the full kit. It's supposed to be low dust but I want no dust. I don't really care about the stainless brake lines either so it's rotors and pads for me.

stop tech areo rotors are made in the usa. but they are exclusively for BBK's(i think). and i can guarantee they are expensive. like 300$ plus for rings alone. each.

stop tech sport rotors are definitely made overseas in asia, with, perhaps, final machining done in the usa. they are drilled and/or slotted centric rotors.

those two piece ecs rotors are superior to sporttech sports in every way.

I upgraded my stock brakes with R1 Concept rotors, Stoptech pads, SS lines and racing fluid. The difference is huge. Pedal feel and braking power improved.

Contact Kevin@R1concept, he's the best!

What is the difference between those and any other company, either than the weight.

meaning other companies one piece rotors? i believe these are the only floating two piece rotor available for fitment with stock calipers.

here is some interesting stuff information from this website:

http://www.zeckhausen.com/How_to_sel...ake_rotors.htm


"2-Piece Floating rotors consist of an iron "friction ring" assembled with float hardware to an aluminum hat or mounting bell. These are available slotted or drilled. 2-Piece rotors offer substantial weight savings over the 1-piece rotors described above, as much as 10 pounds per rotor, depending on the specific application. The design allows the outer friction ring to expand as it's heated, without being constrained by the center section. This prevents rotor "coning" and subsequent tapered pad wear and spongy pedal. Because the center section and friction ring are fabricated from dissimilar materials, conductive heat transfer is reduced, lowering wheel bearing temperatures dramatically. Outer friction rings may be replaced when worn, while reusing the center hat, at substantial cost savings. Click HERE for more details on the hardware and assembly of StopTech floating rotors. For track cars, these are absolute best choice and should be used when available. A disadvantage is significantly higher initial cost. For street cars driven in high-salt/chemical environments, corrosion between the iron friction rings, aluminum hats, and float hardware may lead to reduced product lifetime. This can be mitigated by flushing the brakes with water frequently or swapping back and forth between "summer" and "winter" brakes."

If you're looking for more solid pedal feel and aren't needing larger rotors for track use or bling rotors for street/show the Bimmerworld solid guide rod bushings are dirt cheap and work incredibly well.

Interesting...I had no idea there were upgrades out there for these.

What improvements did you see after swapping them in? Do they require any special maintenance, etc.?

How about SS lines? Did they help at all on your setup?

The pedal went from mushy to solid, very little wasted travel. And the pads no longer have any taper. The guide pins are exposed though so salt and grit from winter driving could be a problem. I used Permatex ceramic brake grease on the pins when I installed them with their bushings, haven't looked at them since, been about 7K miles. They made all the difference, no need to look at BBKs at this point.

No problems with the brakes at all except for the expected clunk due to the XP10 pads every time I brake reversing or going forward again as the pads set. Doesn't have anything to do with the guide pins, happens with the 135i front calipers as well.

It'd be a good idea to check them regularly during the winter if you keep them installed through the worst of it. I'll be replacing the guide pins and bushings with every pad change just to be safe although it's probably not necessary since salt isn't used here when or if it snows/ices.

The stainless lines aren't really necessary and they don't make all that much difference, I think. Debating on whether to swap new OE lines back in.

Just checked into this upgrade. $65 per axle is dirt cheap. I drive a lot... 25k+ a year. Anything I should be worried about? Lubricate and all good?
