My custom 5-Lug

[JTapper]

Details on the actual production and availability of these are coming, but I approached a local forum member about the possibility of building as close to a plug-n-play kit for the E30 5-lug conversion as possible. He came damn close.

These are E36 hubs and brakes installed onto an E30 stock spindle.

Here is the full flickr set:

Warning: have a tube sock handy.

Fully installed. A hex cap screw holds on the cover/key. Everything is SS:


Key removed showing the hub nut/spacer itself.


Spanner tool for installing/removing the nut/spacer:


Spanner tool installed in hub:



A little machining of the caliper bracket was required to clear the stock mounts, caliper adapter visible installed on the spindle:


Fully Assembled:


Spacer/Nut. Threaded to fit stock E30 stub axle:


In all it's glory:


Enlarged backing plate to compensate for the E36 hub/bearing. Presses onto the stock stub axle:


Face of the back plate. Raised area is the outside diameter of the inner race:


Caliper bracket to fit E36 calipers on E30 spindle:


Fitment with ABS sensor:


Just enough clearance:

I want this.

Un-freeking-believable.

Awesome! Great idea on the whole damn thing.

Prices soon?

It's not quite plug-n-play, that's the issue.

He had to machine a little off of the calipers, as well as tap the spindles for the adapter bracket bolts.

I'll be in touch with him soon on the possibility of threading the adapter itself versus the spindle, as they are hardened and most people will not have this ability. The calipers require the use of a mill. Again, something most people don't have access to. The 5-Lug itself is totally plug-n-play though, just not the brakes.

I didn't take shots of the back of the cover/key.

There is a tab that sits in the groove in the end of the stub axle preventing it from unthreading. The hex cap screw will hold the cover/key securely in place. Functional, and beautiful.

It seems like this would cost a lot more than the ~$300 I spent for my front setup, but if not that is awesome.

Is this for the front only? Or is he making something to fit m3 brakes on the rear?

[JTapper]

This is the front only. Spindle adapters will likely run in the sub $200 range. From there you'd have to figure out your own brake situation. If you use E39 brakes, they have a larger rotor than the E36 and you would ber able to run brake adapters without having to modify the caliper brackets.

I decided against that so I would have more wheel clearance with the E36, and I didn't need 12.1" rotors.

Looks like very good work.

Cool idea, looking forward to more info.

Awesome solution. I was planning to build something similar, but didn't get around to messing with it.

Are you sure the caliper adapter can't be made with a tapped hole so people don't have to tap their spindles?

Subscribed. yea!

very interesting. I CAD'd something very similar a while ago, but didn't go into as much detail as you have.

What's kind of offsets are you looking at? Looks very promising. I think if you solve the special tool need and cutting into caliper brackets, you'd have a really awesome design.

This should be possible. The only trouble if that there are clearance issues. If you used E39 brakes I'm sure you would be able to avoid it. Here are come closeups to help you understand:

These were set up for an 8.5" wide ET13 wheel. The hubs protrude 5mm over the face of the E30 stock hub. The backing plate is necessary to make up for the larger diameter of the E36 hub. I'm sure it adds some strength to the stub axle as well, even with the stock one being strong as hell.

As far as the spanner tool, he's looking at coming up with something else, but it seems to be the best option, and will be included with the kit. It makes it possible for the cover/key design to work well with the adapter.
