Hey guys. I've been looking and searching and I don't think I've seen one single lowered M56. I bought a 2011 M56S and I wanna lower it bad. I've only seen a few lowered M37's and M37x's.

I would get coils but honestly I know I'd feel pressured into slamming it. lol. That's stupid reasoning but after constantly replacing axles and bearings in my 2012 G37xS sedan I am not interested in doing that on the M. The Eibach 6397.140 looks promising but I don't think they ever came out of development and it seems no one actually has it on hand.

Bump on this... really close to buying an M56S and have the exact same question.... anyone??

I ended up going with BC Coils

Those concave wheels...mmmmmm...

+1 aaaand it looks mean on coilovers.

car looks amazing... very nice. I have an '07 G35S right now on HSD coils and find it a little too much for the roads/winters we get up here in Canada. Should be picking up the M this weekend and was heavily leaning towards the Eibach Pro-Kit. Had these years ago on my 1st Gen G35 w/Stillen sways which seemed like the perfect street setup. I know there is a weight difference when comparing the M37 to the M56 but is it so considerable that using the Eibach's listed for that application would be out of the question? Thanks for the info!!

anyone???

No one with the V8 has tried the Eibachs..likely why you haven't gotten any responses...there are a few that have put them on their 37's and report no issues.

I see.... perhaps I'll just take a chance and get them... been trying to research the weight difference between both motors without much luck though.

M37x:
Front Rear Total lbs.

2,224 1,819 4,043

M56:
Front Rear Total lbs.

2,246 1,782 4,028

thanks!!! based on this i think it'll workout ok.

My concern with lowering a M56S with a spring kit would be that the struts are specific to the "S" model.

I'm assuming the shocks would have the same spring mounts as the non s model however I'm concerned about the spring rates being a bad match for the s shocks. good point

My thinking exactly, ssaeed. Physical installation should not be an issue, but the mix of components not necessarily designed to work together could adversely affect ride and/or handling.

love everything about my M except the lack of aftermarket support. I really don't want to get coilovers like i had my on old G as the winters up here really took their toll on them.. Guess I'm stuck...

Perhaps I'm missing something but if the springs out there are designed for the RWD 37, then why would putting them on the 56 concern you? Unless I'm mistaken aren't the struts the same for both the RWD V6 and V8?

I know of a person who has lowered their 56S on Tanabe springs, which are also made for the 37. See the picture below:



EDIT: there are in fact two separate part numbers for the RWD M: RWD for the base models and RWD for the sport model

the concern would be the difference in shock calibration between the s and non s models working well with the eibach spring rates. I'm pretty sure the eibachs were probably designed for the non s models.

That, and there is more compression on the strut at ride height, due to the spring being shorter.

Ssaeed, the Tanabe spring rates are probably the closest to stock as you'll get with an aftermarket spring. The Eibachs will not lower the back of your M as much as the front, there are plenty of us M37 guys here still waiting for our Eibach springs to "settle" lol. I suggest if you aren't a coilover guy (as I am not either) go for the Tanabe springs. The OE struts are under additional stress no matter what aftermarket spring you install, get what you want and enjoy the appearance of your car. The S struts actually are better for lowering as they are made stiffer than the non S version and offer additional dampening us non-S guys don't have. When you modify your car you are always going to have to sacrifice somewhere...

BTW DonBlaze: send me those part #s please? I wasn't aware there were separate ones for Sport and non-sport

Yes, agreed that the OE struts are under more stress no matter what brand of spring you install. That being said, they will wear out quicker, too. Replacing "S" struts is not a matter of buying a set of $300 KYB's and calling it good; it is much more expensive to replace the factory "S" struts.

Like you said, "get what you want and enjoy the car". For me personally, I would not lower my M Sport without going to coilovers; but that's just my take on the matter.

Thanks for all the input guys. Does anybody have pictures of a car with the tanabe springs? I ultimately just want to do springs, 20mm spacers and tints and then leave it alone.

Scroll down to the bottom of the page to see the car on springs.

The front wheel gap is still too big with those... wonder if they would settle...

Altered I'll get the part numbers up for u when I get home.

ssaeed, I posted a pic of a 56 up above with the Tanabe springs

Keep in mind as DonBlaze mentioned the M56S weighs more in the front than the M37S in that Tanabe advertisement. There is about a 200 lb difference in the front between the V8 and V6 versions, so your car will have less wheel gap in the front than that link shows.


Don thanks, but I misunderstood you. I thought you were referring to part #s for Tanabe springs in that post.

CURB WEIGHTS..M37.................M56
....................RWD.....AWD......RWD.....AWD

Curb weight (lbs.)

Front.............2,072.....2,224.....2,246....2,405
Rear..............1,786.....1,819.....1,782....1,819
Total.............3,858.....4,063......4,028...4,224

Took these from another website, I think the M37x total weight is incorrect, it adds up to 4,043 if you do the math. But it should give an idea of how the drop will look on a given variety of the M platform.

Hey guys,

ssaeed, did you manage to get the tanabe's? How do the look / ride? I just landed an M56 that I'll be picking up this week, and while I don't want to get anywhere near slamming it, removing a slight bit of wheel gap would be nice.

Just wanted to give you guys a quick update. I ended up installing the Eibach pro-kit springs for the M37 in my M56S about 3 weeks ago. So far no complaints. Ride height is pretty much how it should've been from the factory and it handles pretty much like stock. I also installed 20mm spacers all around. Looks much cleaner now.

Do you have pictures?

have you been able to rotate your wheels? ive heard of Discount tire and other places refusing to touch cars with wheel spacers on them.
