Update: ACS Germany is looking into compatible springs for my vehicle to drop the front an appropriate amount

I made another thread about f31 suspension discussion that talks about the negatives of most of the "affordable" coilovers.

Once again i'm not looking for level, just closer to level than ACS, and even the front lower than the rear is fine with me. just anything other than reverse rake

It never fails to surprise me when people ask for help on the Forum and then spout their expertise in reply.

Mentioning brakes was a bad example. My point was, there are other differences in vehicle weight and distribution apart from the obvious (saloon versus touring). Exhaust system, for example, which can also vary according to engine.

I'm well aware of the 28d lump. We have, or have had, a wide range of diesel 4-pots in the UK market i.e. 16d, 18d, 20d - all substantially lighter than the 25d, 30d, 35d, 40d and 50d 6-cylinder units, and will therefore have a different weight distribution.

Good luck getting your reverse rake sorted. It's a well known problem with ACS springs.

"Spouting my expertise" is unrelated to a known fact on how your vehicle sits with X springs on X platform, that is the unknown for me. Thanks for your time, sorry you're easily upset.

I took your implicit advice and bought the same black caliper at Harbor Freight that you were using in your photos. Makes things so much easier and more accurate than the measurements with the tools that I previously used.

My car is the 2015 335i xdrive modified with Eibach (-06) spring kit for xDrive and Koni Special Active dampers for xDrive. The front tire has a larger gap as is normal from the factory. As you measured on your car, my front to rear gap difference is 11mm on both sides of the car, which is about 7/16".
Interestingly, both right sides are 2.6mm higher than the left sides. That's about 3/32", which isn't perceptible.

I forgot to measure the actual gap between the top of the tire and the fender lip. I usually place a straight edge across the top of the tire. I'll try that with the new calipers.

Hope you hear good news from Europe about your springs. Please keep us posted!

Thank you for that. My car drops about 1/4" when filled up with fuel that could be what you're experiencing.

And yeah I'm trying to locate Eibach springs for my car. It's not sold anywhere by U.S retailers I'm having to buy off eBay from Poland.

Tried contacting ECS To order for me but he said since it's not stocked by U.S Eibach that he can't see or order it from his catalog but he's gonna try to get it for me. If not I'll resort to eBay.

I don't mind if the front sits higher but an almost 20mm gap with ACS is too much for me hopefully it brings it down to 11mm like yours.

In your photo, the rear end on your car really does look too low. I'm curious what shocks you have. Are they stock or upgraded? How does it ride if you have it loaded up with family and luggage?

Check out Amazon UK that automatically does the Euro or Pound conversion to US Dollars when you purchase. I was surprised to find some German-made parts there that aren't well distributed in the US. The UK was actually much cheaper, with reasonable shipping cost that was only about 4-5 days more than if I could have ordered it from a US retailer. One tip that I learned is that you will see a tax that is only supposed to be charged if an item is shipped between countries in the European Union. They are not supposed to charge the tax on shipments to the US but make sure to confirm if you buy from a European supplier (so they don't just add it to their profits like some websites seemed setup to do.)
Good luck!

I am on stock struts, with ACS springs it rides just like stock I honestly can't tell a difference, the handling is much better, but the comfort is exactly the same imo.

I will definitely check out the amazon uk site today

Received an update from ACS, they have a spring that can lower the front 10mm, going to order it Monday and try it out

HI - wondering if you ever got those front springs installed and if your ride height differential, front to rear, looks better now. I have the same issue and it drives me bonkers looking at it. I keep thinking maybe it levels out when I’m driving it (from my weight) but I can’t see that so I don’t care!

Hoping to hear that those front springs sorted your problem.
Cheers, Brian

There was a post I made on here with the updated pictures. I believe it's on the F31 suspension discussion thread. It made an improvement but was not perfect. Was still off by like 5mm or so.

I would just get coilovers
