There's no info regarding whether these are firmer than stock. Or if so how much....

I'm also wondering if these are on par with OEM quality. I don't wanna put just anything on.
Well that's interesting.. ecstuning shows a different design for the rear springs! The adjuster is now at the top with a separate spring spacer/holder lower down between the helper spring and main spring. Should be much easier for adjustment.



As opposed to:



I've only driven MSS' M140i for 15 minutes, but it was less firm than my M235i with M Performance Springs and Bilstein B4 Damptronic shocks. Probably not a fair comparison.

....

found more detailed instructions PDF (see attached PDF)

it appears the adjusters are made by Aalco in Southampton: www.aalco.co.uk

....

for those with an M240i and possibly M235i(?) there appears to be two different part numbers for F22's.

F22's:
02aBMW2F22CP (F22 - Coupe)
02aBMW2F23CB (F23 - Convertible)

"If you have a M240i, we would recommend the MSS BMW F22/F23 M240i Height Adjustment Ride Management"

F22 M240i's:
02aBMWM240CP (F22 - Coupe M240i)
02aBMWM240CB (F23 - Convertible M240i)
https://www.mlperformance.co.uk/prod...wering-springs


and..

F20/21's:
02aBMW1F20HB (F20 - 5 Door Hatchback)
02aBMW1F21HB (F21 - 3 Door Hatchback)

F21 M140i's:
02aBMWM140HB (M140i - 3 Door Hatchback)


Does anyone know what the difference is?
