OBC delete with 3D printed adapter


Gonna stick this on so I can use my phone for navigation etc

Awesome that you're using solidworks for all this. Im a CAD technician myself, however for my job I mainly use Plant 3d. Used SW a little in college, really cool to see someone putting their cad skills to work on e30s. Keep up the good work!

Came across a new 5 lug conversion option.

Creations motorsport for sale on ECS


Looks like it would be a smaller offset change than the ones avaliable for sale by members of this site. Doesn't look there is an accompanying caliper adapter.


They sell this one but the description says it is for 540i/Audi rotor conversion on 4x100 hubs

Subscribed- I am extremely curious to see someone use that kit!

Are you running 318ti brakes in the rear

Sweet thanks, I just put in an order for the hub adapter. For only $78 it's worth checking out. I'll probably end up making my own caliper bracket once I figure out what brakes will work well with this.

I have 318ti brakes on the rear right now, but I have Z4 hubs that I'm gonna put on my old trailing arms with E46 brakes which will need a caliper adapter as well.

Awesome, I'll be following your progress! If you make multiple sets of brackets I'd take one off your hands. I don't have the means to make my own set. The offset is the main reason why I've hesitated to go 5 lug in the front, so if this works out I'll be thrilled.

Also, if you're going Z4 in the rear I'd be interested in the ti brakes and hubs when you take them off. Those just press in/bolt onto the E30 TAs, correct?

Will the E36 hubs + those sleeves work with the E30 ABS system up front?

Oh jesus these hub adapters are garbage.

Check the inner diameter of the E36 bearing.


And here's the OD on the Hub adapter


And again the E30 spindle diameter

Big DO NOT BUY. Calling ECS for my refund

Subbed!

Awesome thread! Love the work you're putting in to get it just right. I just recently purchased an E30 and have slowly been getting it up the snuff.

Noticed you're Markert Motorworks License plate frame. Will you be out at the meet and greet their having this Sunday?

Yeah I'm gonna head up there after BMWCCA autocross. Probably will take my E46 since it'll be hot and my E30 sucks on the highway.

LOL at those hub adapters. They need to be careful selling those, there are definitely people out there that are dumb enough to install them

Its well passed time for me to machine my own adapter. I'm gonna make up some drawings and talk to some guys about material selection this week.

I think I've written a bit about different kits in this threads but I want to make a summary post.

So the 5 lug conversion options for E30 are either E30 M3, combination of E36 stuff, or hub adapters.

All hub adapters on the market today have similar issues.
Every hub adapter kit adds something like 12-14mm of offset. This isnt really an issue as its not to hard to find higher offset wheels to fit, but some of the fan favorite wheels are lower offset 5 lug.
The reason for this is they all use E36/E46 rotors which have a width (wheel mounting face to back of rotor) of about 52mm. E30 rotor width is 35mm.

So most of the apater sleeves just have the extra width at the base and push the ABS ring out of the range of the sensor. Namely:
ngampleh's ETA adapters
Max399 adapters

nasieg adapters adapters have some of the extra width in a spacer that goes behind the rotor so ABS works.
same design as elcoy if he still sells them

My goal is to make low offset adding adapter (E30 M3 width basically) so I can run 225/45 on an E38 Style 5.

The only 5x120 rotor with a lower width is the E30 M3 rotor which has a 40mm width. (seems like E30 M3 suspension is about 5mm more width per side) This rotor isnt that much of a size upgrade if you're going through the whole 5 lug process.

So I'm gonna need to redrill a rotor from another brand to 5x120. Should be fun.
