Just wondering if anyone's running a setup like this. All I've seen is more spacer mm in the front than the rear. Are you guys doing this for the flush look? Or are there handling characteristic improvements for that?

I just got my Kwv3 installed. Going to be dialing in the settings and height soon. I have 15 and 12 spacers so I'm contemplating which is use. I've always liked the flush wide rear look.

This was my previous M3, ran 15f, 12r on Dinan. Nice and flush but would rub in the back occasionally. I like the flush look more so than dropped but ideally both for the most aggressive look. The trick is to not rub under all circumstances. Even the occasional rub was unacceptable to me.

12mm in the rear will definitely give u a flush look.

I wonder if 20 in the front would be too much or not. Would rolling rear fenders help eliminate the rub?

There is a whole thread regarding spacers. Personally, I have run 12/15, 15/12, 15/15 and 18/15 with H&R springs and no issues.

15/12mm is very popular for those running stock wheel/tires. Plenty of examples can be found in this thread:

Hope this helps!

Thanks guys. Gonna run 15f/12r. After I tweak the KW height I'll take pics.

I am running 12.5 f/r on ZCP wheels. Many with ZCP wheels are running 15f/12r with no issues (assuming stock sized tires). Since ZCP wheels are 4mm closer to the fender stock, you should be able to run 18f/15r no issue with non-ZCP wheels.

Increasing rear track width relative to the front will increase understeer.

I am considering spacers with 15mm Front/ 12mm Rear coz they're the most common measurement recommended by everyone in this forum for a stock e92M3 with ZCP. But when I took measurement, there's barely any space left between the well and tire-lip when I measured as shown below. There's about 3-4mm space for the front and barely 3mm for the rear. Am I doing the correct measurement here? I was hoping to have no rubbing. Should I stick to 15/12? Appreciate your insights Thanks in advance

when I run my OEM wheels I run 18f/15f with no issues.

You also have to remember when the suspension compresses that the wheel will also camber in (negative) a bit so the clearance you see uncompressed, isn't the same as it is when it is compressed.
