H&R specific to M5C and H&R M550i Springs

Hello to the group. Trying to parse through lots of good info on this the site in reference to the H&R springs. I've never changed springs so my technical insight is lacking.

I'm trying to lower my 2021 M5C just a little and I want to maintain the factory ride as much as I can. Would like it to be noticeable, without sitting it on the ground. Which option would you recommend? Also can you make the switch without any additional modifications or adjustments such as spacers?



Thanks for your assistance.

You can make switch without spacers.

HR M5 springs are a more subtle drop while the HR M550 springs are a little more aggressive.

Search here for pics of both and see what you like better.

Vic55 has had both so good point of reference.

I'm on HR550 springs and here's a pic:

Another option is MSS spring.
It is adjustable and fraction the price off KW HAS.

That way you can adjust it to your liking.
