Style 87's but centerbore/offsets are off.

I'll admit I have not looked at what's on the market for E70 platform, but if I had to choose....Neez all the way.

NEEZ International - BMW Forged Wheels

It's been awhile since I've price out a set but I would guess 10K and up for a set of Neez wheels. They are extremely well built, strong and 100% forged.
