Do not use Ehrlich Wheel Works

[Tbonem3]

I still don't understand how they don't fit - 10"et25 is a very common size - don't tons of people run that? I just fit a 9.5et22 e88 wheel on my car with big 996 calipers and there was TONS of room like 1/2" or 12mm betwen caliper and wheel spokes.

Sorry you have to go thru all this nonsense. Just out of curiosity what Brembo kit are you running? I had to use utilize 18mm front wheel spacers to fit ZCP wheels to accommodate Brembo GT 380mm with 4-piston calipers.

So here's a massive BBK and his set up is an effective offset of 29 and clears, so how is 25 not clearing? I understand spoke/wheel design matters, but my E88s with et22 would be similar to OP's e88s no?

When I get my M359s for my E90, I'll take a rear wheel (10"et25) and fit it on my E46 front axle to see the clearance - now I'm curious as hell.

I guess that Schirmer state their sets may need the spacer to cover fitment issues... however my Schirmer E88's in 18x10 / 18x10.5 and AP Racing 6-pot CP9040 / 362mm fit just fine with plenty of clearance and no spacer FWIW

This is what I would expect. Maybe Schrimer was advising a spacer up front to clear their nitrons or something special because it doesn't make sense that an agressive wheel like 10"et21 would need a spacer to clear typical struts and typical BBKs. Fitting a 10"et21 on e46 is already so difficult, how could you also expect to get a 5mm spacer in there?

I threw on my 9.5"et22 E88 wheel on E46 with zcp rotors and big reds (996s). There's a lot of room, can get a finger in her. Does the Dinan BBK stick outboard more than other brembos or something?

looks like he's running a double stepped setup, so wouldn’t that make the centers same size as yours?

I have no idea! I just find it really hard to believe that a 10"et25 wouldn't clear bbk.

The barrel has no effect on brake clearance, that's all the face of the wheel. Mine are 620 faces.

You can see the face here, it's the last 3 digits in that string, these are 171s.


Paul has the 996 calipers on his car, and he said they fit. I think these F50 calipers are just bigger. But like Jay said, this is about as common of a BBK as you can get.


Here's how mine look


They hit the rim of the wheel not the spokes

Hmm thanks for adding a pic cause I still was having trouble envisioning this. So it's more an issue with the 3 piece wheel construction/combination than normal metrics like wheel size and offset alone.

And your caliper, even if it's not abnormally large, because it sits farther outboard from hub due to larger rotor, does come into contact with whwre the wheel face meets the rim which is even tighter it looks like.

A true 19" e88 would probably clear then right? Things are tight because it's an 18" face adapted to 19" barrel?

Geez...that is as standard as standard could come. Any progress? Let me know, I can go scorched earth on this dude. He'll be like...who da fuk is dis? lol

I have seen DINAN Brembo kits that are 380s. I can't tell if OP has 380 or 355 fronts.

When you say rim of the wheel, you mean the center register?

I think tbone has summarized the situation nicely in that sentence. I'm sure this is what the issue is, but a wheel builder should absolutely realize that depending on the precise brake kit involved clearance could be an issue.

[Tbonem3]

And given that other 355mm BBKs from brembo and AP seem to fit 18" e88s, maybe we could conclude OP's rotors are 380mm like Slideways alluded to? Which I swear has always been a no-no for 18" wheels. Maybe OP does only have 355mm rotors, but due to the adaptation of 18" faces to 19" barrel, that alone makes it a no-go.

Which yes, I would agree that Paul with Elhrich wheels should have known or at least advised caution on, not told OP "Yes you're good" or whatever was said.

Given how this has gone extracting details from OP, it's not surprising the order went like this... zero details have been freely given on anything that could determine what would and what wouldn't fit OP's brakes...we're 4 pages deep and no one in here can conclusively say what brake setup OP has... shocking

likely not 1/1 as yours are the old style, but, if 380mm Dinan does have printable templates for all their brake kits brembo_brake_kit.pdf

[Slideways]

I looked up a image of E46 M3 specific Brembo GT 355 kits.



While DINAN 19s were designed to clear 380s without spacers, many other wheels were not.

Edit: OP posted that the kit is 355mm

I literally posted a picture of the brake setup. They are 355mm discs with F50 calipers.

Pretty standard stuff.


The E88 face determines brake clearance, nothing else.

19" E88s are just 18" faces stepped to 19" barrels... 19" faces don't exist unfortunately
