Installed Eibach Z4 3.0 lower springs .8” drop

[OF Hero]

Anyone have the euro spec Eibachs and running TE37SLs? What tire size would you recommend that wouldn't rub (street use, not track). 265/35 and 295/35 or would you recommend a 30 aspect ratio instead?

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!

Thanks bushido, glad to hear you're tracking the car with the Euro Eibach springs. Yes I already have a front sway bar. What else do you have besides springs and a bar?

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.

Appreciate it, but again to confirm, you ran the US version, not the Euro version?

I'm tempted to go to Ohlins or Fortune 510's, but by the time you add in the coilovers, the camber plates and the EDC cancellers you're ~3-4 x as much some springs & camber plates.

I don’t think you will rub with either. I would do the 295/35.

I probably did have the US version. Which is not a problem for most people. Also helps that bushido is on his 265/35-19 wheels

With coilovers or springs, make sure you’re tucked in far enough (negative camber) to not hit the wheel well (hood in our case), while still avoiding the coilovers or springs when the wheel is fully turned. Those are areas most track guys are surprised when they open the hood and see the black tire marks.

Thanks FL, yah the plan, in addition to these springs (or the RSR Sus Springs), is to run Verus Camber plates, I already have the BMW Camber Correction Knuckles so I shouldn't have any issues achieving -3.0° of Camber. And hopefully on a 275/30/18 on an 18x10 +30 wheel (square).

I've had SPL endlinks on my 2023 for two seasons of autocross and a couple track days, no issues. I had a clunk from my bar and thought it was the endlink, SPL sent me replacement spherical rod ends no questions asked. Turned out it was a loose nut holding the swaybar bracket (those nuts are TTY BTW)

You should be fine on your SPL goodies if you’re extra careful not to drive on them when misaligned. I now have all my SPL parts (front end) in a box. The adjustable LCAs are practically new, since they sent me their latest and greatest “FK Rod Ends and High Misalignment Spherical Bearings” with Stainless Steel spacers for my last event. I’ll have to post the whole lot for sale when I get around to it.

Let me know once you do, I may choose the Easy Button here and leave my suspension as is (all stock sans FSB and Swivel Bearings) and only add an SPL LCA to get some negative camber. Then save up for some coilovers.

That’d be your best bet. Learn from others mistakes (like me). Get the best coilovers you can afford & adjustable end links, LCAs and whatever else you or your suspension shop determines is needed to properly articulate the geometry of your setup.

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

Looks amazing like this!
Did you order the same part number: E10-20-046-02-22? (since you have a MT)
Also, did you cut your bump stops?


@Andrew4Supra thanks for sharing this info!!

Is anyone running these springs with aftermarket wheels that have these specs:
Front: 19 x 9.5 +22 | Rear 19 x 10.5 +35
Tires: Front 255/35/19 | Rear 275 35 19

I want to avoid any/all rubbing if possible.

Edit: If it matters, I won't be tracking the car. Thanks!

I'm running the Z4 Eibach Euro springs with Advan GTs 19x9.5+25 & 19x10.5+32 on 265/35 & 285/35 with ZL1 splash guards all around. No rubbing.
