Please by all means share my comments there if you can. I can't post there as a commercial entity.

Also, do you have a hyperlink to that group? I'd love to see what is being said. Thanks!

Link above is sharing your comment, there’s many post in that group about fake calipers if you search bbk or signature werks or zl1 etc… it’s a shame really how many people are willing to risk theirs and others lives on these fake or grey market kits. The owners of sig werks have even went as far to use alternate accounts to make comments on post praising their products or shutting down anyone who questions them…

Just posting this as more info. I know the magnetic paddle shifters are sourced from China so if anyone can find the supplier lmk. Then we can do a group buy

Love the info if you find anything else, keep it coming…

I found the combination of m4 calipers with Maserati quattroporte 6 piston (30,34,38mm) and Porsche Panamera rear 4 piston (32/32mm) should work well. Has anyone come across plans for brackets?

Is there any information if the m4 calipers will clear the stock 220m wheels? Can someone confirm I can’t seem to find info on that thanks.

If you are talking about the f80 blue brakes, yes.

Yes and thank u sir

I managed to get some pads made up to fit the F8x discs perfectly using the W204 C63 callipers so no more annoying rust ring!
If there is enough interest I can get some more made up.

These pads also work with the Alfa calipers? if so i'd be down for a set

Hi guys. I recently bought a 2011 E90 comp that has C63 calipers and 380 mm F80 rotors in the front. It has the original comp wheels so everything fits no issues right now. I want to eventually step down to 18's (I'm considering the Apex VS-5RS). Has anyone been able to run 18's with this setup? I know F80's are offered with OEM 18's. I know that Apex list that some BBK kits (like 380 mm Brembo and Stoptech) fit their wheels. It seems that these C63 calipers are really large though. I don't have a lot of clearance between the caliper and the inner wheel barrel and I'm don't know if it's the calipers or the 359 inner barrel is smaller than normal.

I'm 99.9% sure the alfa pads share the same pad size so 189mm x 9x let me do some comparisons between the two pads and I'll post up my results.

I'm 100% I was wrong, They do not share the same pad size.

Interesting question, I've been in a similar position myself but with trying to fit the G8x front brakes on my e92 with the 359m wheels, The inner barrel on the comp wheels are certainly smaller than most 19" wheels, I measured at the point the calliper would sit I had 44.5mm clearance inside the wheel, Most other 19" wheels I measured had 46mm clearance.

I'm going to borrow my mates track 260M this week to see if they clear my C63 brakes now.

Sounds good, any additional feedback would be appreciated!

Anyone running a ZL1 kit?

are you talking about the alibaba china express zl1 kit from signaturewerks aka jqwerks aka aka mashimarho aka essj0n aka precisiondynamics aka spencerberke?

nah dude wrote

okay good just wanted to make sure nobody fell for this death trap

Chalkbr wrote

They basically got exposed for selling Alibaba rotors with their "kits" on the e9x owners group

nah dude wrote

ha, wow. it's interesting how that FB group has a strong list of sellers pushing chinese products for this platform, but pretty much all the vendors on this forum seem to sell legit stuff. I think you have to pay to be a vendor here? maybe that's the difference.

So I really like how this BBK "looks" so I did some digging and research, I asked them on IG who makes their rotors for longterm use and replacement incase they werent in business and they just responded with "they're our rotors".. little sus. to me.

Rather spend more and deal with Stoptechs BS knockback issue...

I came across this..

Looks like the company "Dicase" makes this BBK.. Similar packaging etc.

After test fitting this afternoon, The square set will not spin without a 15mm spacer but that will put it beyond the edge of the wing, It does however spin with a 15mm spacer but does catch in areas I suppose the wheel is slightly buckled from track curbs.

I'm going to ask the same friend if he has any fronts I could try as that might work in our favour by giving a slight bit more clearance.

Dicase brakes are the top tier of all China brands (ppl even copy them) and you should be fine using them for anything other than a pure track car. Dicase are OEM manufacturer for many brands, including Brembo, and also release their own products under their own brand. There's a full interior E60 M5 here running Dicase 380mm front/rear who is a terror in the hills and also very very fast at track. The driver is a bit of a madman and really leans on the brakes. I think there's a pic somewhere of the M5 at Sepang F1 track with glowing orange rotors. The Dicase have held up with zero issues. Quality/tech wise, I would say they are on par with Brembo GT. I would not be surprised if they came off the same assembly line. Sure you don't get the branding, but you don't have to pay for it either.

The only reasons not to get Dicase brakes are #becauseChina and they do copy the tech of the bigger brand names. That said, do make sure you are getting original Dicase and not a knockoff.

Edited - Found the pic of the M5...

Super interesting! I never heard of them until doing some digging on Signature and stumbled on those videos, their website looks like a cheap knockoff website.

Id love to hear from SW to see where they source they rotors from and more than just “they’re our own” answer.

Thanks for the info!

It didn't help their branding that their first name was "Dickass". 😂

Thanks for the feedback. If OEM 260's fit I'm going to have to assume APEX will fit.

I see a lot of you say the alfa and ghibli are nearly identical .

If they are identical can I use the alfa pads that were posted that have a better sweep ?

Not liking these pad sweep at all.

I guess anything d1666 . That's the max from what I am seeing 65mm radial pad depth
