Minute 12:10 shows the control arm process. It's the older X5 but serves the same purpose. I lowered it about 1.3inches so I deducted that from the control arm measurement when tightening.

I bought the FCP Euro arms in the original post and I do have the LCI.

Hey everyone,

I just purchased an X5 M competition early this summer, I just noticed it had aftermarket lower springs which the dealer pointed out. I’m hearing a weird faint clunking noise whenever I go over a small bum at very low speeds after my X5M has been sitting overnight. The delear couldn’t find the problem so I’m guessing it has to be in the aftermarket suspension. So I’m going to purchase new lowering springs and install the control arms needed to dial in the alignment.

Can someone give me guidance on what’s best between springs and or H.A.S suspension? Then also everything I would need to purchase for correcting the alignment once I’ve installed the new suspension?

Dinan doesn’t mention the UCA and one would think they would given their thoroughness.

Literally no company will suggest items to fix something like this unless they have their own product to sell. They're just selling the springs and unfortunately it's up to the customer to figure out a fix.

Seems like you are forgetting that I am the one who figured it out and shared my finding.

Dinan Springs Install review:

So I finally pulled the trigger and installed some lowering springs on my F95 X5MC. The reason is funny. I didn’t think the car looked aggressive enough and I seriously considered trading it in for the new M5. I had the F10 M5 and it was my favorite car and I kept it for 7 years which is by far the longest of all. But, once I found out my trade in value for the X5MC and the depreciation hit I decided to go for the springs.

Review: this is what the car needs. The factory set up provides exceptional handling but the ride height limits your confidence during aggressive cornering, which is my favorite! With the dinan springs installed i think this car is bad ass. I want to drive it! It handles like a sedan and it has the power and cargo capacity to boot.

The dinan springs are very slightly stiffer but not really noticeable. The body roll or lack there off is awesome. The lower ride height inspires confidence which driving. Aesthetically, it looks perfect. I’m not sure why BMW left the wheel gap in the front but it detracts from what this car is supposed to be - a street beast! Now it looks perfect. It’s a shame that I had to drop $2500 to make the car look bad ass but I saved $25K on a trade in hit for an M5 so I guess that works! Pics below w 10 MM spacers all around on Dinan Springs. Last pic is stock.

After taking another look, it was just over $2200. The labor was about $1700 and all the parts came to around $450. I bought spacers, longer bolts, and the bump stop kit. No UCA but I’m thinking about them now.

What did the alignment sheets say with your setup now? If it looks like some I've seen deep in the red, then I'd swap the UCA's before you burn your tires out.

-2.1 on the FL and -2.0 on FR. Toe was within specs. FWIW, I’ve got the UCA replacement scheduled!

Thanks for tall the great info and insight guys. Always appreciate peoples experience.

I'm looking to upgrade to X5M in the coming months from a 50i. I had the air suspension so I know things will be drastically different all around. I have 2 kids and this is my family car so I was wondering (and I know it's an opinion) which lowering setup/set would get me the desired better stance but not take too much away from the comfort of original ride? Is an adjustable setup better since I can play around with it?

Thanks

I wouldn't slam it all the sway down and leave around 10mm front and 15mm rear for a good stance and for comfort. Adjustable springs would be the best choice for this reason, plus if you decided to add a different wheel/tire setup in the future to account for the rake.

Nice. Thanks for the tip!

I noticed in an earlier post you said you ended up going 13mm/15mm vs 10mm/15mm. Was there a noticeable difference between the 10mm vs 13mm in the front?
