Ebay - supposed to be delivered this week per the tracking number I received, so pretty fast shipping. https://www.ebay.com/itm/184497855474

I wonder if this is a reputable source? Link

Always wondered if there was a post about Z4 Euro Specs (Installed back in 2020).

Here are some pics of my ride on Euro Specs. Quite a few mods done.

OEM wheels - Spacers 13mm (f) / 15mm (r)
Vossen HF5 - +6 offset 4mm (f) / +18 offset 13mm (r)
Tires - Nitto 555 G2 265/35/19 (f) / Nitto 555 R2 285/35/19 (r)

I‘ve got the US spec Eibac springs with Verus camber plates installed. Any idea what I should ask for them? They were too low for tracking on a 275/35-18 square setup, for me. I didn’t get rub until really high speed corners on compression. They did look great though!

I ran them for about 4 months. The springs were $350 and camber plates $459. The front springs are still loaded on the stock shocks and I’ll let them go with the set. I have no clue what those cost, @FuzzyRev85 . I have Ohlins now. So no need for any of it.

I would say list them for 600 obo, and sometimes I’ll eat the shipping cost to get it out of my hair. I don’t like to let things just sit.

I thought it was the Euro spec spring where you rubbed? Or have you run both and rubbed with both?

I bought them from Speed Industry. Assuming they are US, the lower of the two. They were fine until I went to Homestead and increase my speeds at turn one. Nice compression at over 100 mph. I was running over the rumbles as well. So under extreme conditions, they can definitely rub.

I’ve only owned this one set. It came with sway bars. Again, the looks are great and it rode nicely. But I would not recommend them for track.

Now this makes more sense, your story of excessive compression and rubbing, as you had the original US-spec Pro-Kit, which lowers twice as much up front and 1.5 times as much in the rear as the Euro kit. That's far too much for a "street" spring to have a real benefit on track. Also, historically speaking, the Pro-Kits have never really been an appropriate track spring for most applications, as they're too low and too soft. They're a great street spring, nothing more.

The OEM front struts list for $814.76 each, and could be potentially had new for as low as $550, but we all know that used stock parts are mere pennies on the dollar, if worth anything at all (i.e. exhaust). Are you still using OE rear shocks or are those sitting around as well? Just thinking out loud because the full set of springs, plates, and updated 2021/2022 dampers would be insanely appealing if I was an owner of a 2020...

Exactly! I should have just stuck to the Eibach sway bars. The stock OEM springs would have been perfect for track use, in my case.

The rear Eibach springs are shown pictured on the ground. So I do have them all. No crazy rush to sell. But realize those springs are no longer made. If someone wanted that lower look and lived in Florida, it may be what they’re looking for. Absolutely no rub when not tracking. Since the camber plates are already installed, no need for me to take the whole thing apart if anyone is interested. And it is nice to be able to dial in more camber. I can do that with my adjustable control arms, so no need for the Verus plates anymore.

Thanks for the feedback brother!

I just did the euro spec eibach and love them. Ride is good. I wish the front could be a tad lower but the ride feels like factory. And we did trim the bump stops. Before and after shots

~1 week after the install.
Car pulling to the right a little.
Alignment shop said still too early and needs to settle.
Going to do a steering recalibration, doubt it'll help.


What alignment specs is everyone running/using?


Seen this thread:

I don’t of the latest… It turned into a SPL part workshop between my Hunter alignment shop and SPL. They went back and forth on some of the bolts that came with the parts. Ultimately SPL offered to send me another control arm (sounds crazy but totally forgot!) and my alignment guru went and bought some bolts. SPL was really helpful! I’m going again after my new tie rods are put on and will post it on here. Have an appointment for this Thursday ?

I have Eibach springs and sway bars (front and rear). Will likely do coilovers next season.

This was my previous alignment from another place. Great shop too! But he couldn’t code out the steering angle sensor & said he’d call me when they release the software updates on SnapOn. Another alignment shop I used to use a lot told me the same thing.

Just had mine aligned...

I’m running negative 2 degrees front and rear. Eibach Z4 Euro Springs (-.8”). Burger Tuning wheel spacers (10mm/13mm).

Update:
Recalibrated EPS, will see if it drives more straight 2mrrw.
Recalibrated ride height sensors, ISTA says it affects body control (suspension, lighting, etc.)
