Running 19x8.5 ET40 235/35/19 in the front for my E92.
Lowered on H&R sport.
I'm thinking of getting a 12mm spacer, I read that ET30 will work perfectly fine without problems at all. But will that extra 2mm cause problems? Just don't want to regret in getting a 10mm when a 12mm could have been perfect.
Here is a picture of how it looks in the front right now to give you an idea of the tire's side wall as well.
**12mm spacers arrived, it rubs when doing u-turns (near-max to max turning angle) but it seems like there is still some roof left to space out. 15mm-17mm would make it look perfect, but it would rub like mad.
10mm would probably be safer, but I never track the car so I am happy with the 12mm spacers. Right now the thin trim/edge of the tire is right at the fender, would look better if the part where the tire starts curving most is at the fender for a slight poke look.**
