Best retrofit for M3 brakes?

Ignore the rusty rotor, had to give them liners a clean and dress up. Rears was a breeze. Rear center cap is giving me anxiety not being straight with the 'M' badge

Do you think you would have gotten a full sweep if you used the stock e9X front rotors?

[pbonsalb]

Weren’t they stock E9x v8 M3 front rotors? I think he wound have gotten full sweep with either stock E9x M3 front calipers or brackets to properly mount the other calipers to fit the stock M3 rotors.

Yes. But visually with M4 rears (370mm) and smaller fronts it would have looked off. The sweep isn't concerning me too much, nothing a splash of high temp silver paint can't remedy.

If it bothers me I'd have 2 pc rotor with smaller pad area, but that defeats the purpose of this being cost effective solution. Otherwise there are other solutions now available via Epoustouflant

The braking force and overall performance is very noticeable.

Thanks for the reply and pointing out the off look with the M4 rears. Do you think this set up would clear 18” rims?

Depends on the 18s but I suspect it will be tight

where are we sourcing the alfa calipers from? does anyone have the part numbers?

Has anyone seen this?

Also, there are GT350 adaptations for the E9x M3. What do everyone think about it?

This is interesting… Please post photos/names too, so years later when the link dies, the info is still available to whoever is reading this thread.

I've gone another route with my brakes, but I always wondered. Wilwood makes some pretty small calipers, why is it there isn't a Wilwood kit for this chassis yet? or at minimum someone working a bracket to make them work?

[SilverSlug]

I think it's because the same reason why we people don't typically put Magnaflow mufflers on Beemers.

You mean because of quality or musclecar-ness?

lol it was way awkward, as I asked him about the dude he is doing a group by for previously being banned like a week before, then I couldnt find his threads either, because he himself was banned

Really?! Why what did he do? I thought he was a forum sponsor/supporter?

To be fair the BBK he had on offer was pretty complete, i'd have jumped on it if I didn't follow through the Alfa setup I did in this thread.

I actually participated with his brembo BBK retrofit group buy. I was wondering if anyone else has and if y'all know what the status is because I'm STILL waiting on an update and he hasn't provided much feedback other than "should be soon" for about 2 months now.

If anyone else also joined Matt Di Vita's (epoustouflant) groupbuy and knows what's going on, let me know. Thanks!

Try emailing the group buy guy directly? or messaging on Instagram?

I see a new post, story, etc. about a group buy posted like every day, sometimes multiple a day. If he doesn't respond to your Insta message, you are being ghosted.

Damn those gt350r calipers and rotors like like a steal... 2300 barely even buys you a set of bmw rotors lol

I saw that groupbuy. I'm in a different group buy with him, and things seem to be going fine, hes been responsive to the communication I've had with him.

The one thing, I will say- I've been around car forums for quite a while. Group buys and custom orders for things like this happen all the time for different things for different platforms.

When you have a group buy for a custom run of parts, delays happen. Its always some minor or crazy reason, but people usually in the end get their parts. Often its longer than promised. Sometimes far longer.

This group buy was for Sloan Workshop if I remember correctly. You've got parts being made and shipped out of Russia. I would wager a guess that Matt's probably just waiting on things to arrive, and can't make the process go any faster. Sounds like hes at least giving you updates when you ask, even if the update is I have no update.

It's better to say I have no update when asked than to say nothing at all, so that in itself seems like effort there.

All in all- I'd say go into any group buy like this with your expectations set correctly. Group buys of custom parts never go as fast as you expect them to.

You are spot on. I got a message this morning and apparently Slon Workshop has been waiting on components that took forever to get delivered so they could finish the kits. They plan to ship out all the kits next week though. You're right, I need to manage my expectations better with these group buys. I guess I was just getting a bit impatient because of the money I dropped. If it was a few hundred, meh...but a couple thousand, I was expecting in-transit visibility lol

Will the 19" 220 wheels set clear the Brembo BBK ?

[SilverSlug]

Yes, they should be able to clear the BBK.

Thanks just want to be sure before I place the order. front is 365mm X 34 and rear is 345mm X 28 Brembo GT.

[rod.bearings]

Looking for more rear calipers options. Currently top on my list is f80 rear which is bolt on
Second, Panamera calipers (require bit of machining) + MLT bracket
Third, Alfa Romeo rear caliper + freak parts bracket

My fronts will be c63 caliper + freaky parts bracket but it’s been hard finding f80 rear calipers so seeing if there are more options. Not fond of the second or third choice at the moment

Edit - I noticed MLT has bracket for CLS calipers, does any know the piston specs for these or how you all found that info for each caliper?
