Thumbs down Ichiban wheel adapter review. VERY IMPORTANT TO READ!

So I bought some MAE crown jewels to use on my car this year. They have a 5x114.3 lug pattern and a mystery centerbore. The only adapters that i could find for japanese wheels on a bmw were ichiba pre made. I should have just gone custom

first of all. they include lugs to bolt the adapter to the hub, but no lug nuts to bolt the wheel to the adapter. there goes $50 for some gorilla lugs

The second problem was the centerbore was wacked out. it needed to be 60.1mm but it was 73.1. thats fine. i already knew i would have to fix that. first i go to fix it by removing the centerbore on the adapter. that was no problem. i'll make a new insert to fix the centerbore.

so i go to mount the adapter for a test fit. it doesn't sit flush on the hub they didn't chamfer the center of the adapter for the shape of the bmw's hub. great. I brought the test adapter back and added my own chamfer. Now it sits flush.

So then i mount the adapter on again. great it sits flush this time. So I mount my new wheel for a test fit. it sits flush with the fender so its a good offset. Alright so what I do next isn't a super great idea but it is done all the time with much success. The wheels i bought were unfinished so i was going to start polishing them by spinning them on the hub as a sort of lathe so i can get good polishing action with some sandpaper. With the other wheel on the ground (so it doesn't spin when i add resistance sanding the spinning wheel in the air.) I go to start the car and put it in gear, and the car jumps off the jack! What happened was the lugs that ichiban supplied with the 15mm adapters were too long! they interfered with the internal drum brake in the hub used for the handbrake!!!!! this caused the only drive wheel to be the wheel on the ground which launched the car forward. the damage was minimal but its like come on give me a freaking break. everything about the adapter was wrong. they are advertized for bmw fitment. in reality they were thrown together and were not tested for our cars at all! Be warned! if i had the car on the ground and went to drive off with them, who knows how much damage it would do to the handbrake and rear hub.

current oz futuras which i'll be sticking with for a while.








flat spot from dragging on tar. also slightly bent


lug on right made contact with handbrake.


left one is unmodified. right has chamfer machined in.

That really stinks, but it could have been WAY worse. Thanks for the heads up.

OP, were you able to use the adapters? I recently bought 2 sets so i could use my JDM Zauber Gettins on my E90 330XI. I haven't tried mounting them on my car yet, however i test fitted the adapters on the rims and they fit just fine. Luckily, the centerbore on my rims are 73.1mm so no problems there. The centerbore on your MAE Crowns were 60.1mm, correct?

I'm just wondering if the hub-side part of the adapters will work fine on my car w/o chamfering them. Did you have to bring them to a machine shop to get them modified? Also, i know a few forum members from E90post who had problems with lugs being too long with their 15mm h&r spacers and had to shave them down a few mm's. I'm thinking of doing the same with the lugs and probably the chamfer issue on these adapters.

wait...so you lifted one wheel up in the air on the jack, then intended to put the car in gear so you could have one wheel spinning to polish it with some sand paper?

So you put the car in gear while one side was on the jack and expected what?

I wouldn't have done that myself, but i'm sure the OP has done it before w/ success. =)

update. I finished shortening the rest of the lugs and machining the rest of the adapters. I got the wheels finished and they are looking pretty good! no vibrations!

That looks pretty unique, it has a real Euro flavour to it. I haven't seen a set of MAEs in ages..
