This weekend I have replaced the wheels and tires on the E30 B6. I had decided on a set of “style 5 v2, 8jx16 ET23” from the E38 7 series. I just thought they would look better than the standard E30 M3 wheels due to the extra “edge on the rim”. And in my humble opinion, they actually do! I am very happy with the result. Offset is almost the same, just with an extra half inch in width.
When putting the wheels at the front, it didn’t fit directly. There was some slight interference between the hub of the wheel and the inner side of the brake caliper, but a 5mm spacer made it work. Tires are Conti SportContact 2 in the difficult to find size 225/45ZR16. There are still a few other suppliers for those, but I felt Conti’s were the best choice (before Falken’s FK452). Due to starting rain, thunder and lightning, I haven’t driven the car yet with this set-up. The stance is very nice, but maybe a little more offset at the rear would make it even better. I kinda like a “stanced look”, but am not a big fan of spacers in general; normally only when really needed. I will probably give it a go with 10 or 15mm spacers and see if “Stance Works” will approve.
One concern from the drivability front; when taking off the 3 piece BBS wheels, I could clearly notice a weight difference. These style 5’s are definitely heavier. Let’s see how this will affect handling. According to me, the standard 16 wheels for the E30 M3 are 8.22 kg (7.5jx16 ET27) and these ones 8.53 kg. That difference is not so much, so probably all will be ok. But couldn’t find the weight of the BBS’s yet.
