M4 380mm brake rotors fits E92 m3 hub?

[becausephilchow]

I'm sure you can get F8X Calipers to fit the E9X with some custom brackets.

Same way people get 17Z/18Z/19Z Cayenne Calipers to fit many many other cars with custom brackets too.

You might have some unswept area on the rotor if it doesn't match up well, but, you should still be able to make it work.

Nope, m4 brake rotor fit perfectly on e92 m3 hub. rotor hat offset is identical like on e92 m3 360mm rotor.

I was talking about calipers not rotors .glad they are the same .when will you try the calipers .

yes custom bracket will need for sure, my friend is professional machine man so adapters will not be any problem to make them. i am waiting calipers to come from the germany, i will update info for a few days. i found information on one forum,forgot to bookmar it- rear m4 2pot caliper is direct bolt on e92 350mm rotor. so i will bought also 2pot rear calipers.

Ok cool let me I will want a pair also

Using the brakes from the newer platform isn't going to affect bias in any significant way in this particular case.

Understood. My point is that I think you would be better off keeping your OE brakes instead of building a Frankenbrake. I know it's been done before on other platforms, and I know many people swear it works great. I'm just not a believer in going this route. I would rather save my money and stick with OE. Upgrade the pads, lines and fluid.

I already got new rotors and upgraded pads , new brake fluid bleeded .still e92 m3 calipers is for sure the weak point. You cannot go wrong with m4 brembo oem calipers ,at least that should be a upgraded over oem e92 m3 calipers.

why you call that frankbrake? if m4 rotors fits just like oem+m4 brake calipers+m4 brake pads, only need adapter for calipers?? many after market kit from what i saw comming also with brake adapter lol. then aftermarket brakes are also frankbrakes.

+ i all got for a few hundreds €

My skepticism is based on the fact that you are installing brakes from a completely different platform, possibly different bias, and different???, onto your car and calling it an upgrade. I'm not a brake engineer and I don't know if the two cars have the same brake bias. Hopefully you have researched that and any other potential issues. I'm thinking not based on your responses. An aftermarket BBK from a reputable company has been designed and tested to work with the car it is to be installed onto.

^^^The 2 platforms are within 100#s of one another, and both have a 50/50 weight distribution.

Furthermore, ECS already offers a kit using the F80 bits and custom brackets...so I highly doubt the OP will be dying in a fiery crash anytime soon.

I don't feel the need for a brake upgrade, but I would definitely consider fabbing some brackets for F80 bits, if I did!

Find out the master cylinder bore size of the F80/82 then you should have a better indicator of bias. Note, on a lot of modern cars bias can be controlled by the ABS control module pump. Some people with RE experience should really delve into other control units rather than just "cracking" ECUs/DMEs. We're now in such era of motoring now

Or how about if you don't have the funds to do it right, go ahead and save your money, run the more than adequate stock brakes, refrain from building a Frankenbrake and don't worry what your friends think? I know that you are being sarcastic but you are supporting my point.

FWIW - I currently only have a front BBK and run upgraded lines and pads on the rear. Guess what? It is fantastic on the track. I'll be grabbing the matching Essex rear kit once released - but I must admit that it's not necessary.

On my previous car (e46 M3), I found a front Brembo BBK brand new, in the box, for $2,500. Ran that on numerous track days with upgraded pads and lines in the rear. Zero issues and saved some cash. I'm not suggesting that everyone needs to buy the best. I'm just saying don't spend your money on a "performance" mod that doesn't actually improve performance. Keep an eye on the used market for a BBK. There are often lightly used kits in the for-sale section.

Just another overpriced bbk

I wouldn't call AP Racing overpriced whatsoever. They're the best.

Overkill for a streetcar? Absolutely. I agree with slicer that the OEM brakes are more than enough with a proper track pad, good fluid and lines.

Why is it over priced? Compared to what?

Edit - just saw the link in your signature. I now understand your perspective. Yes, the Essex kit is not worth it for the use of your car. Stretched tires, heavy wheels, wide body. You have zero use for a BBK.

$4k is over priced for front brakes, specially on an underpowered car like the E92, it's overkill.
get your little butt hurt out of here lol
Btw that car is probably tracked more than yours, between drift events and Highway runs and is very soon being tuned for E85 SC, shooting for 600 whp, and I still don't think I will need larger brakes for $4k.

I will say this: in my s/c'er plans, I planned on upgrading to a BBK. Making the car that much faster, and increasing the ability to accelerate that much faster, I felt it would be irresponsible to *not* decrease the stopping power, as well. I opted for the Albert racing BBK, which utilizes the stock rotors but much bigger calipers. 8 piston fronts/4 piston rears for less than $3400 (when I got them due to the exchange rate) seems like a worthwhile investment for me.

Ok bro Have fun on your highway runs. I bet the soccer moms are really impressed when you blow past their minivan.

Great idea , keep us posted!!!

I made this mistake with the F10 M5 kit. Fitment limited me to 19" wheels - and even then, I was rubbing inner barrel. I'm glad I bit the bullet and did the correct thing with a proper E9x BBK.

This. I got my Stoptech 380/355 kit new for 3600. That even included the Tiffany Blue paint and caliper rebuild.
