Yes, those are what we fitted. The caliper casting is very similar to the radial mount version. We had to make a fixture for the CNC mill and use the Brembo factory drawings to determine where the mounting holes would be located. It's not something that a person can do in their home shop, but it's well worth the effort.
I'll be adding a lot more E90 specific stuff to the Facebook page soon. I'm using the 4 piston front and rear with factory rotors on my car, although the 6-piston fronts look bad ass.

Here's a set that is now on my Z3 MCoupe. You can see how we machined the rears and created a custom mounting bracket. Sorry for the large picture.

Any problems (or solution) with the soft peddal issue?

[vasillalov]

The key is to match the total piston area to the stockers. Brembo, Stoptech, Willwood and almost all of the other BBK manufacturers design their calipers to have custom piston sizes. An ST60 caliper for Camaro may have completely different pistons from ST60 caliper for E90. The pistons are sized correctly for the master brake cylinder.

Whatever you choose for calipers, make sure they are progressive, two piece calipers.

I have f30 performance front brake set.
Thinking about fitting in f30/e92m3 master cylinder.
Any suggestions?

Do you have the only the front calipers installed?
You shouldn't be getting a soft pedal on only with front calipers its when you have the front & rear installed is when you should get the softer pedal

[Wlodi]

Do U know anyone with f30 370mm Performance (not msport 340mm) brakes with no "soft pedal problem" ? Im getting soft pedal - system was bleed twice. I read that some people have same issues with just the front calipers installed.
Thats why im thinking about e92 m3 master cylinder.

Another thing. I read that Performance BBK fits 18" wheels.
On the other hand I read that people who put it on e9x have to use at least 19" wheels. Whats the difference ? Cant I just buy 18" f30 wheels ?

Several member have done just the front caliper upgrade with no issues of soft pedal in fact they say pedal feels much more firm with brembo 4pot f30 calipers

You can try an upgrade to stainless steel line?

Is the F30 front performance caliper a direct bolt on? Would we need to buy other parts?

Machining the calipers into radial mount versions and creating brackets took a little longer, but was well worth it.

Did you get a soft pedal after installing the cts-v caliper like the guys are getting with the f30 brembo pref calipers??

Yes it's a direct bolt up

[Oo vvR3cKz oO 619]

I'll read up on this later
Good stuff...

Thanks for the reply, I notice I am unable to order just the fronts am I correct? From what I am reading so far the whole front kit rotors/calipers are a direct fit, but the rear calipers will cause a soft pedal.

I have only fronts and have soft pedal issue. Read that I am not the only one.

Did you upgrade the brake lines?

Proper bleeding?

What brake fluid did you use?

Thanks

[Wlodi]

Did te bleeding twice.
Dont know what brake fluid. Asked for DOT5.
Didnt upgrade the brake lines.
Probably will:
1. change brake fluid and bleed the brakes.
2. Change brake lines
3. Get the m3 master cylinder.

Anybody ?

[wshgrntd]

Have you upgraded the master cylinder yet?

[Torgus]

Brake lines will not do anything fwiw. I assume we all know why upgraded brake lines are used...

Any updates on this?

[wshgrntd]

iS ANYONE SURE THAT THE REAR ROTORS AND CALIPERS ARE THE SAME ON THE 330?

[anielsen71]

Hi guys
I just talked to the local shop today about fitting the F30 M performance brakes on my E91.
He dosent see any problems with pedal feel or brake bias.
We prob Will have a look at fitting the rear brakes also. Will prob be done at the end of jan. Will keep you posted.....

This is nothing new. It has been done many times before.
I have done it a year ago.
The pedal will be softer and it will increase front bias if you leave the rears stock.
You can play with different pads in the rear to make it better.

No they are not.
They use different parking brake shoes.
335i are larger.
