*KITS HAVE SHIPPED* 5 Lug and BBK Group Buy Round 3

[elcoy]

ok but the same rotor is used on both m3 and z4 hubs
and the only difference in the adapter on the z4 is shaved down 2mm
if it's just the caliper then it doesn't matter.
i'm guessing you're talking about the the brackets being different?

To me it looks like calipers are the same
The 99+ brackets looks like they get pushed out 3mm. is that what you have?

Correct same rotor. The bracket in the rear holds the caliper, not the hub. RealOEM has the caliper carriers all the same (34211163648). I guess I am just going off what I have confirmation fits.

Got it.
looks like those are the early pre-facelift carriers.
540/530 are the same exact calipers & carriers

They only change after the facelift because the different rotor offset.

Did u also use the same carrier on the m3 hub ones? Check the p/ns.

Yes I did use the same carrier that came with the calipers.

Pictures update!

Parts are finishing machining and headed to plating early next week.













Group buy pricing ends when I get parts!

That is a thing of beauty. I better start refinishing my calipers.

What's everyone else planning on running for wheels? Everything I find that I like has +20 offset.

[LowR3V'in]

20 is great for the rear. maybe add a little spacer because the z4 hub.
but the front it's going to be suuuper flush. Probably stretch a tire or definitely get the fender rolled.

Thanks for the info, that opens up my options a bit!

Do you have/sell brackets for using the z4 hub instead of the m3? (got kit from nasieg group buy).
Are instructions available somewhere?

This is a product write up I stumbled across awhile back.

[elcoy]

Good news, kits have shipped to customers!

Let me know if you need the instructions/parts list. I decided to do digital copies instead of printing off all those pages. Most people already received it via email.

ahhh these pics are making me regret not jumping in on this

[-J-]

Awwww yeaaaa.



I have to say I'm really impressed with the machining and anodizing quality. I had a bit of sticker shock when I opted in but these really are top notch parts.

For the last few months, I've only been buying parts for my '67 mustang project. When this package showed up I was very confused for a second. lol. Really excited to get these put on my e30! All the parts look so nice!
