Mubea HD springs ? any experience?

So I just noticed both my rear coils are broken and I jumped on a deal at ECS for MUBEA HD coils.
I know they will be stiffer but Im wondering how much stiffer and if they have a height difference from OE.


Thought of going with H&R but decided to just focus on having this thing reliable and spend the $ on maintenance.


Any input would be greatly appreciated, I still have time to swap them for Febi/Bilstein OE standard...

I haven't had any experience with "Mubea" but both springs have the bottom broken on my wifes X3. I know when I looked into it there was 2 or 3 different part numbers depending on factors such as if it had the pano roof etc. My thinking was that the car rides rough enough as it is I wanted to avoid "heavy duty." The springs have been broken for a couple of years and I still don't have the new springs installed so I can't comment on how that turned out though

Looking at FCP and ECS, they don't state if Pano roof or not... Sport suspension or Standard suspension is the only thing I noticed. From what I understand is the HD springs are same as Sport (stiffer) for more load capacity. I do trailer motorcycles from time to time and do use a bike rack on the hitch... the car is narurally stiff so yeah, im slightly concerned it might be too rough with these... but at $95 for the two, I couldn't say no to them....

I suggest getting them swapped, I noticed my tires getting warn out on the insides like mad.

I would never have noticed that they broke if I wasn't looking right at it the break.
If your tires are wearing that much there is probably more going on.

I ordered all (I think) the parts to redo the rear suspension at the same time as the springs, just need to get around to it!

just an update, Installed the Heavy duty springs and they feel same as OEM.. or maybe my ass dyno is just that soft I can't tell. In any case, happy with them, especially with the sale i got on them.
