Best lowering springs NON ZCP

[bmwpower603]

I am looking to get lowering springs on my 2008 e90.

Racing Dynamics no longer makes lowering springs. So now I’m stuck buying different ones. Which springs will have a ride height similar to RD?

Will I need to replace my shock absorbers?

I currently have the 19” wheels with stock suspension.

Been contemplating the same and think I've decided on KW height adjustable springs.

They are a little more expensive than just a straight spring setup. But the ability to adjust the height for front/rear and get it set exactly where you want it is worth the extra cost IMO.

The idea of spending $300 on springs and being stuck with the height (love it or not) just seems like something I'd end up regretting.

Good looking e90 BTW.

Thank you for the compliment my friend. Hoping to get it looking even better with less Gap. I think I like the car 10 times more when it’s lowered.

Those adjustable springs seem to be the answer. I wonder how many times it will need to be adjusted, to look even all the way around.

I’ve never had coil overs on my cars. So never had to adjust a suspension.

I'm actually going against my past direction this time around. I opted w/ Swift Springs and a set of Bilsten B8 struts/shocks. I actually was a firm believer in coils w/ my past cars but ended up finding a height i was happy with and never really touched them again. This plus never getting around to tracking my car I just felt that extra money would go great on other mods or maintenance.

Here's mine on Eibach Pro Kit, Interlagos Blue E90, same as you. They quote .8 lower in front, .6 in the rear. I'm not into tinkering too much with the suspension, but that adjustable set sounds pretty cool.

Love my Dinan springs. Drop is conservative but ride quality is near stock.

Swift Spec R with Bilstein B6 EDC. I'm very happy with the look and the ride.

Eibach prokit gets another vote from me.

[bmwpower603]

If I go with the adjustable springs, or eibach. Will I need to change my shock setup?

The bilstein EDC is big $. If I can do just the springs. That would be easier on my wallet.

[RE36TRO]

Those Interlagos E90's are great examples of a nice ride height.

The forum consensus will probably tell you that only a spring setup is doable however will eventually catch up to your stock shocks/struts in terms of premature failure....even more so if you're in the higher mileage range.

Swift, eibach, H&R.

Anyone have a comparison photo between e92 ZCP and Eibach pro sport springs. Not sure if the drop is worth spending the money

Below is E92 ZCP drop

Below is E92 ZCP drop

If OP had a ZCP I agree it might not be worth it, but he's on stock non-ZCP suspension.

I have the Eibach springs, I parked next to an E90 ZCP at the grocery store awhile back, my car sat a bit lower - my eyes could definitely see a difference. Eibach claims .8 inches lower up front, that's 20mm lower than stock while ZCP is 10mm lower. Mine actually settled closer to an inch up front, the back a little less.

[GORDON.M3]

ZCP is pretty close but the eibach front springs drop it a tad lower. The rears aren't much change.

Here is the Eibach Pro-Kit front drop.

Man your car looks great... def jealous of the IB e90s.

I don't want to really ticker with my suspension either honestly, but if you had the choice would you go a tad lower if you could?

Thanks, appreciate it. I'm very much a fan of your SG/FR E90 too!

No, I wouldn't want it any lower, personally. I'm trying to retain an OEM+ look, and I enjoy having stock ride quality. Perhaps if I had aftermarket wheels I'd want it a hair lower

What was the spec on this car? We've had someone fit Eibach Pro springs recently on the UK forum, but the rear dropped a lot. The rear wheels are slightly within the arches so I'm trying to determine if this is common with the E90 M3s. I have Eibachs that I need to fit, I may end up purchasing zcp springs if this is common.

Non ZCP E90, Eibach Pro Kit, spacers (15 front, 12 rear).

Never heard of an Eibach spring dropping the car a lot - maybe depends on what your definition of 'a lot' is? These springs are quoted at .8 inches front & .6 inches rear, and that's where they settled. Which is about double what a ZCP spring lowers the car from Non ZCP (.8 inches = 20mm, ZCP is 10mm lower). Still wouldn't call it really low.

I run Swift spec-r on stock shocks, I like them a lot

Here's an image of the car in reference. The rear tyre goes slightly into the arch.



The blue E90 in this thread has a bit of clearance.

Camber angle could be a factor there

His cars currently completely stock other than the eibachs installed recently. I'll check if he had an alignment done following install.
