Installed Eibach Z4 3.0 lower springs .8” drop

[Basil_a]

Agreed! I was torn between the two kits and seems you can’t go wrong!
Cheap eBay CF kit. Was like $190 shipped. Best fitment I’ve seen. I must have lucked out.

Just realized you are on Apex wheels with some Continentals! I have been thinking of doing a similar setup. Mind sharing your tire specs and maybe more pictures? Thanks!

Sure thing! I was gonna do some pictures and walk around video at some point with the springs / spacers. Car is so filthy from pollen. May take me a day or two to find the right spot / clean the damn car

Will tag you if I post here! Just in the garage now

Does anyone know what the (ft/lb) rates are for the front and rear Euro Z4 Eibachs? Can't seem to find that anywhere.

Just installed these on my 2023 MT. Ride height is perfect and there’s no noticeable change in ride quality.


Also for anyone wondering, quickjacks still fit under the car just fine. I was slightly worried about that before installing the springs.

About 7" clearance from the bottom of the front bumper and 4.5" from the bottom of the side skirts

Did you guys have to cut the bumpstops to install the springs?

~ yes ... front and rear bump stops. cut one donut off (the smallest one).

Yup. I did the same thing.

Hey all, just wanted to make sure that these are the correct euro spec/Z4 springs (maybe the "pro kit" terminology is tripping me up...thought that was for the US spec which was lower?):

Those are the correct ones, part number looks good

Bump so has anyone tracked their cars on these (Euro version) Eibach springs?

Just a quick mention for anyone doing a lot of tracking. Under high speeds and compression these springs may be too low (or perhaps soft). I’m getting tire rub & therefore switching to Ohlins coilovers. Just wanted y’all to be aware - if your intent is to do lots of track days. Also, I’m on 275/35-18 tires. Great size for different brands, compounds and ability to rotate. But it does contribute to a lower profile.

No hating on Eibach by any means. I have their sway bars and love em. These springs would be great at canyon carving, for looks or maybe even okay on track with the stock wheels ?

So just circling back on this, from reading through this thread you were on the US spring which lower the car roughly 1.5" vs the Euro version which only lower the car ~0.8"?

Tempted to run these springs (Euro version) along with some Verus camber plates and a 275/30/18 tire on an 18x10 +30 wheel on my 2023 MT but don't want it to rub on track.

Just installed these on my 2023 MT. Ride height is perfect and there’s no noticeable change in ride quality.

You went with the Euro Spec springs on your MT? Some folks now saying the US version lowers the MT cars by the same amount?

Doesn't make sense to me as the MT is only ~30lbs lighter than the At.

yep, slight improvement in handling, but these springs are very soft. pair them with a front sway bar

i'm on stock wheels running 265/35 front so i can't answer your rubbing question. sorry!

Yes mine are the euro spec springs. These specifically: https://www.amazon.com/dp/B0842828FH?ref=ppx_yo2ov_dt_b_fed_asin_title

Here is another picture that shows the ride height after having a few months to settle.

If I were to do it over again, I’d skip either Eibach (US or Euro) lowering springs spring for tracking. And went straight to coilovers with linear or stiffer spring. But for most peeps, Eibach lowering springs won’t be a problem - not tracking. I unfortunately didn’t and inevitably rubbed ?

Edit: Happy ending (story): I sold them to a member on this forum who could give 2 shits about tracking and loved them.
