M4 rear spacers - 12 or 15?

[NiceGuyEddie]

I have seen both in pics, but neither in person. Hard to discern the difference in pics. Has anyone actually made the switch from one to the other? I am looking for a flush look with no poke - any suggestions?

Stock suspension and 19s.

The shop I take my car to had both 12mm and 15mm spacers in stock, so I was able to try both in person.

IMO, the 15mm was a bit too aggressive up front as it stuck out of the fenders a tiny bit. I ended up going with the 12mm all around. Looks perfect. Also, I have H&R SS springs = perfect stance.

12/15mm combo should be perfectly fine, you can go a bit more aggressive if you do not plan on lowering.

Here is a M4 we just did 15mm spacers and the KW HAS kit on. It is sitting perfect now! Please click HERE if you have any questions

12 all around. With 15 it looks like you added spacers. It's out of,place. With 12 it looks like it could have come from factory.

I put the 12/15 on but just bought some 12's to replace the 15's. They stick out too much in front with 15's

15s all around here with kw v3s

does this set up kick up much of anything on the side of the car ??

small rocks, dirt etc.. or is it still flush enough that crap doesn't fly up on the lower body of the car..

I'm still torn on going 12f12r or 15f12r

I will no be lowering... adaptive susp and 19"s

Get 15f12r... especially if you are NOT lowering

M4 stock suspension, with adaptive, and 19s. It sits rather flush and I went 15/15.

I saw some pics with the 12 in the rear and I personally think the extra 3mm makes a difference, I want an aggressive look to match the rest of the car.

I may lower one day as I dont like the gap, but with relation to wheel flushness, I think its perfect.

I have 15 front and 12 rear now - ordered a new set (due to vibrations) and am going down to 12 front. 15 front was a little pokey for me.

You think that at first but they look perfect. Either way

[TRKY]

I have 12mm on front and rear.

15mm front and 12mm rear looks the best. By the way, which brand spacers had vibration? Did you use a wire brush to clean off the hub ring before installing the spacers?

Edit: I saw your post, it's BMS spacers that had vibration. Try to clean the hub ring with a wire brush and re-install. Please report back if this solved the issue or not.

A safe brand has been M&S. No complaints so far by anyone.

[AlphaOmega4]

Think I'm going to go 15f12r.

if I end up thinking the front is to aggressive I can always change out the front to 12



Thanks Guys!!!

Would you recommend this for anyone who is considering lowering via kw has? I have the adaptive suspension and the kw has is the best option. I want a flush look but do not want to worry about rubbing nor do I want to deal with rolling my fenders. Any advice for my situation?

F82 adaptive m suspension kw has currently considering 12 mm rear x 15 mm front

[CPWINCH]

there is an entire thread for this in the wheel/tire forum. I went with 20mm front and 15mm rear. 20 in the front because I have camber plate and will be running aggressive negative camber upfront for the track

Here's the wheel/spacer fitment thread for those interested:
