Alpina 15" ET12 fitment question

Wed Sep 03, 2008 3:01 pm

Hi to all,

I've just fetched some very nice wheels for my E30, Alpina 15x7 ET12, type 09.
they are the original wheels fitted on E21's Alpina, quite a rare catch.

I heard that the can fit on E30s but would like to have some of your experience...

Do you think they will fit with a -30mm lowered of the car and with 205/55-15 front and back ?

If not then maybe they can fit with 195/60-15.

I've already been to the tyres size calculators like this one :

but it doesn't tell me much about how big are the front and back wheel wells of the E30...

I am pretty sure they will fit, but if somebody with experience has tried this offset and relatively small size before, I would love to know.

You guys fit 16, 17 even 18 inches wheels on your E30 so I am pretty confident.

Hope you can have an answer for me.

Cheers / Pierre

The standard ET for 7x15 on an E30 is 24 so there is a 12mm difference I suggest a trial and error fitment.

you may need to extend/roll the arches or fit a spacer

Have I got it backwards or does that mean the wheels will be 12mm further outboard than a standard set?

I have a slight body contact issue on the rear with my et13 MiM's.
It's not on the arch lip, but the outside edge of the inner arch, just above the lip.

Spacer would make the problem - if there is one - worse.

You are right, Spacer will make things much worse...
i think the wheel well of the E30 is quite big, but it might actually rub in the inside front fender plastic cover.

Anyone else got any more feedback ??

this may help explain offset

so to confirm then for my peace of mind the ET on bmw's is negative offset

No, it's positive.
