Probabbly just two piece (just direct bolts through) will be possible

You might have more room than that if you can make the rotor hat smaller in diameter (which you should be able to do). I just replaced my stock brakes (312x24mm front rotor) with the M Sport brakes this weekend and the rotor hats on the stock brakes are smaller in diameter (I'll put a pic up later).

Based upon the drawing above, on the M sport rotors it looks like there's 23.7mm from the edge of the wheel bolt holes till the hat starts to curve down (184mm diameter of flat face on hat minus 120mm hole spacing diameter and 16.6mm hole diameter).

On the stock brake rotor, the spacing from the inner hub/axle hole to the wheel bolt hole looks about the same (maybe slightly less) as the spacing from the wheel bolt hole to the edge of the flat face of the hat. So if we take the diameter of the wheel bolt hole "ring" (120mm), minus a wheel bolt hole diameter (16.6mm) to get to the inner edge of the wheel bolts (103.4mm diameter), then subtract the hub/axle hole size (79.074mm) we get a difference of 24.326mm and a distance of 12.163mm from the wheel bolt hole to the center hub/axle hole.

If we add that 24.326mm to the 136.6mm outer diameter of the wheel bolt holes ring we get 160.926mm giving you 62.074mm (31.037mm each side) of space between the hat and friction/clamp area on the rotor if you have a "stock brake" sized hat.

For every day driving would be fine. If you track and using sticky tires and aggressive pads? They will need to be STRONG!

That was my misunderstanding
I have this on my car using it just for track days last 5 years

Very good point, 30+mm is enough for sure

Looks solid. Please give us more info and photos.

Thanks man,
I sent this off to Nashin and I'll see what comes back. It's definitely doable because ECS sells them. Just need to find someone who does it for the right price.

Once we know that Nashin make them we can organise a group buy.

They make 370mm already. 32mm and 34mm thick https://www.nashinusa.com/discs and have hats for e9x so they won't be developing brand new product I think. http://www.1addicts.com/forums/showp...3&postcount=83. However, they won't be cheap.

It doesn't show dimensions though so need to check. Yes they won't be cheap but I'm hoping cheaper than ECS at least. I'm also reaching out to DBA today. Aussie company !!! Probably made in China though lol

[Aus335iguy]

It looks like DBA have made custom sets of hats and rings for around 2k for front and back if a group buy of 10 or more people were to pre order.

If they are willing to do this for us, it would mean that the rear calliper would be bolt on with the exception of drilling the holes out to 12 mm.

Not saying this is going to happen but how many people would like to have a set that bolts on at around that price?

feuer we would need to figure out disc dimensions based on the 535 disc just set the disc inboard by about 3 -4 mm and smaller in diameter by 4mm am I right ?

[FaRKle!]

Stock vs M Sport rotors (front). Notice how much larger the hat is on the M Sport rotor.


Rear rotors:

It is BBK from XYZ racing, price is under 5000$ for all around (355x32 6pot fully floating front & 330x32 4pot fully floating rear).

More info you can find on their pages xyz-racing.com

ECS does fully floating replacement for Mperformance brakes?? I cannot find it, can you post a link?

Group buy for reasonable price would be great but for me only fully floating replacement, two piece replacement is not what I'm looking for

Rear rotors:

Wow it's a big difference but at rear it looks almost same size, am I right? Probably because of hand brake??

At rear axle there is no way to fit fully floating rotors, only possibility is to get different brake caliper bracket (holder) and get larger diameter as on M2/3/4 are

You posted it earlier in this thread...correction they are ONLY semi floating...https://www.ecstuning.com/b-ecs-part...09607ecs01akt/

[Aus335iguy]

The reply from Nashin ..
Hi,

Thanks for the further information, however, after checking, we are not able to make the floating rotor to fit with your demand, since the biggest friction area we can do is 57mm but the one you need is (370-223)/2=73.5mm.
Hope your understanding

[feuer]

Is Ok Aus335iguy I would much rather spend the money on better caliper and pads than true floating 2 piece rotors.

Yeah, the rear hats are about the same size.

You are right, maybe 6pot 380x32 + 4pot 355x32 fully floating

[Aus335iguy]

If you don't have the m performers already then yes.

I have 370x30 4pot + 345x24 2pot, but have you ever seen how tiny the front pads are? When I see the price for 2-piece rotors in 370x30 (not even floating), it's about 1/3 of price complete BBK 380x32 8pot fully floating just saying

DBA replied
This OE number of 34106797603 is a x/drilled design, and the normal type rotor OE reference is 3410679606.

Our DBA reference is DBA2286E base number, and the 5000 series number is a DBA52286SLVS T3 slotted or SLVXD X/Drilled & dimpled.

The specs of our DBA is 370x73.1x30x28x79x5 stud.

Brakes direct has the drilled versions for 340aud each....

Correction the discs and hats are 540aud each and replacement rotors are 340

[Aus335iguy]

Does anyone have any others to add?

Stop tech semi floating two piece front rotors, again nearly 1000US bucks for two
