Ok, he did, but with what rotor? Re-read the thread. Both threads actually.

Seems like he only went with the 535i f10 rotor to avoid having to "grind" or remove dust shield in the back. So the 135i 2 piston caliper bolts right up to the 335i rotor if you don't care for the backing plate/heat shield or trim it up. My apologies, I missed that when I was reading that thread.

So 135i rear caliper made to work with 324mm rear rotor on the 135i will fit over 336mm e90 335i rotor and over 330mm f10 535i rotor? Not to be sarcastic but I guess if that is true I learn something new today.

Yea I guess I'm not reading everything correctly. I'll keep reading up and try to figure it out. Sorry

I was going to fit the 340mm version discs with blue 4 piston calipers on the front of my 2009 335i are there any issues with the mv4 225 wheels clearing these calipers? Looking at it theres plenty of clearance just wanted to make sure. Thanks.

I have the same wheels but haven't fitted my set just yet. Looking at where the existing calipers sit and how big the new ones are i think it will fit. If you've already bought them you can bolt them on without doing the bleeding to check I suppose.

Ironically the bigger 370 mm discs would have more room because they place the calipers further out and because the wheels are concave there's more room

I can't for the life of me find a RHD m3 master cylinder. I did find a similar one on eBay that has 27 and 22 stamped on it and the m3 one is 26 and 22

Will this work ?

The number seems to correspond to the bore of the cylinder itself

Anyone know ?
It would seem that the 5/6 series brake booster is even bigger ?

[juld0zer]

5/6 series uses a TRW booster and master, as does the X5/X6.
You cant use a master designed for a TRW booster in an ATE booster as the pushrods are not adjustable and i'm sure there are other physical constraints.

I figured for 100 bucks it looked like it would fit....
are you sure it won't fit ?

were you able to install them after all?

The disks are different f30 vs f80 as are the mounting points for the caliper which is identical.
The f80 caliber mounting point steps the calliper position out 5mm in radius which in turn lets you run a 10 mm bigger rotor in diameter

eBay says it arrives 27th June so I guess I'll find out then. Might buy an ATE booster for cheap just to mock up how I'm going to make it fit ....

Thanks for the response!
So can the F80 calipers be used with appropriate wheels?
I have a set of 513M wheels, and the local guy I got the wheels from is also selling the F80 brakes...

Have a look through the thread and see if someone else has done it before to be sure

What is the question here? Whether 513m style wheels that are factory equipment on F80 will clear F80 brake calipers, also factory equipment on F80. Seriously guys?

[R99]

What is the confusion?

F80 calipers are the same caliper as the F30 callipers. They are stamped as 370/380 on them as they work with either discs - depending on which car they are being mounted to.

As you are fitting to a E series car, the option you have is to fit the F80 M3 calipers with F30 370mm rotors - this is plug and play.

If you want to use the 380mm F80 rotor, this is not plug and play.

Also, yes the F80 calipers with 370mm rotor will fit under 513M.

[AlexN]

Thanks guys,
Should have better phrased my last question..

So can the F80 calipers be used with appropriate wheels? (on an E92)

Obviously, the brakes fit behind these wheels as they are OEM equipment.
the question was about using the F80 calipers on an E92 and sounds like that is possible when combining them with 370mm rotors.

Oh, pardon me, I wasn't aware that your e92 is different than the e92 that this thread was originally started for.

Don't mind feuer
He gets grumpy because he's helped so many people (me included) and I think it wears on him.

If those rims fit on an e92 and that's what you have and you want this conversion you need the callipers with 370/380 stamped on them, 370mm disks(look through the thread there's part numbers. If the wheels you mention are from an f80 they will definitely fit.

Exactly! You are relatively new on this thread and I bet you that if you stay long enough you will to become easily irritated too when people post questions on matters answered previously in the thread, or different thread, instead doing their own leg work. Do you agree? I mean come on! Above questions? So simple premise. Like 1+1=2
