Some people describe it like the car is bottoming out. basically you feel it in the chassis. Usually you'll hear and feel a thump in the chassis.

Absolutely no issues here and i have to go over 10 speed bumps on the way home and on the way to work every day. Car feels solid.

My right rear is sitting lower after installing the H&R kit... think I have a bad bag?

Probably. I had the exact same thing happen. I will post pics if I get a chance soon.

2" lower. How does it feel 😝

I found that my bags were fine and I had just needed to correctly calibrate the links as I thought the shop that installed my kit did...(they told me they did)... they were quite off. At 67mm, it sits perfect and the ride is pretty close to stock, except over potholes and larger bumps. I still need to replace the rear bumpstops though. I'm lowered on the H&R 2" kit btw.

HR or HR VTF?

I've got H&R2.0 on and the ride sucks.

Normal driving is fine with no bumps and flat road and handling is great. Any minor bumps at speed (50+) are spine shattering.

I took a major transition from tarmac to bridge the other day at 70+ and it literally felt like my car got air it bounced so hard off the frame.

While it looks awesome, the ride is severely compromised.

I'm immediately looking for a coilover solution. I love the look but I cannot stand the ride- and this is coming from someone who had race suspension and solid mounts in prior platforms. It's downright dangerous hitting major transitions in the road now.

Be warned.

i got the 1.2" and i also find the ride pretty bad... normal flat roads are fine but when i go over a speed bump or a pot hole it hurts lol . Im not sure if the place i got it installed did the rear links properly (they probably didnt measure 67mm) i need to take it to another shop that have installed h&r springs on other bmws.

Did you get the F10 M5 bumpstops? Mine rides perfect.

Was coming back to say that... might be the bump stops that helped because I don't have that... did you adjust the links with a caliper to 67mm ncbimma? Mine felt like that until I got both sides to 67mm, this is how far mine were off and it sucked

they probably didnt do that....i think they probaably just used a measuring tape
is it suppose to be end of screw to the other end ?

I did not use a caliper but a shop ruler from the same set as the calipers so they should be accurate. Once I installed the new bags from arnott the X5M was higher with the links at 67mm. I didn't like it so we compensated to 65mm and it's prefect now. The ride is a little bit tighter than OE. Absolutely love it.

[ncbimma]

Yeah no caliper measurements here...I did center to center at 67 on the links but the fender height was too high in rear. Ended up dropping it 2 more rotations to get ground to fender lip all equal. I don't like the jawknee look with the rear raised higher than front.

Also on stock e70 bumpstops so I'm sure those are hitting.

Sounds like a lot of you guys need to adjust the rear higher with links or have blown rear shocks. At least with 1.2” H&R lowering springs, the ride is barely different on my old 2007 struts.

I think its a combo of ride height, rear bags life and mileage on rear shocks plus lack of F10 M5 Bumpstops.....

Just picked up a 2012 X5M, will the H&R 1.2 and 31337847472 M5 bump stops fit my vehicle? I want to address wheel gap without sacrificing ride quality but I saw a note on the springs set about "For vehicles without self leveling suspension"

1.2" kit (retains OE ride, just a tiny bit tighter and firmer):

https://www.ecstuning.com/b-h-and-r-...g-set/50435-4/

Bump stops, order 4 (F10 M5 Comp):
https://www.ecstuning.com/b-genuine-...f/31337847472/

and if you are on stock 20" wheels i recommend 15/20mm spacers.

the 2.0" kit is too harsh and bouncy but if your fine with that its here:

Thanks man! Did the new links in your photos come with the kit or did you order those separately as well?

They come with the kit bud. Make sure you install the bumpstops on all four corners of the car and not just the front. Order 4.
