I currently have 704 M sport suspension on 120d LCI 2017.
Would like to upgrade with m performace suspension kit 33 50 2 409 926

Can I keep springs from M sport suspension, because kit is without springs?
Will there be any change in car height?
Are the M sport springs too long for performance shocks?

I like the current height of car just want little more supportive shocks, I think this kit is a great price considering you get all the other parts included.

Thanks

The kit takes springs of it's own (particular springs depend on the car's options, thus a table is mentioned rather than part numbers provided): https://www.realoem.com/bmw/enUS/sho...22#33502409926.

It will lower the car 10 mm more from your M-Sport (that's 20 mm from the basic suspension height). I barely recall that myself and people confirm: https://www.2addicts.com/forums/showthread.php?t=938832.

Thanks I am aware there is a table for M performace springs but cannot find it anywhere.

But my question is will stock M sport springs fit and work with M performance suspension?
I would like to keep existing height of the car.

Here is a reference (in a post there): https://www.babybmw.net/threads/corr...number.147640/. And there are plenty of spring discussions on that site as well.

I don't know if you can keep your springs with that kit, I just think you shouldn't if you trust BMW engineers (Why did you buy their car? ). If you know better (what you want ) there are third-party suspension tuning options mentioned both here and on the other site I've just referenced.

I upgraded to Bilstein B8 with Eibach pro kit.

From M sport suspension car is lower for about 1cm, handling in corners is improved.
Very happy with this upgrade.

This is Bilstein B12 pro kit

Cheeper upgrade than OEM M performance

I hope it will last
