Rigidity: Blistein or M performance suspension for m240i

[LamedonM]

I have sort of made up my mind, my m240i needs a more rigid suspension and spring. I don’t care for lowering. Blistein B12 sport line suspension kit for m240i would cost £764 to buy whilst BMW m performance suspension checked against my car vin would cost £1350.00 and it says only with springs.

Does anybody have experience of either or preferably both

Thanks

I haven’t had great experience of Bilstein, 4 damper failures on two cars (two still in warranty), my local guys won’t use them anymore because of quality and recommend KW

[LamedonM]

Is KW better than M Performance?

[LamedonM]

Will KW coilover street performance type be as rigid as M competition cars?

Have a chat to Birds auto in Slough. They have a lot of experience in BMW suspensions. A few threads on them if you do a search. Mike Cooper who is a superb driving coach for both the road and track rates their setup highly on the 130i.
Their website is down at the moment but there is some good info on there.

No commercial interest in them.

I’ve got a Birds set up on my F31, wouldn’t go down that route again, better options for similar money (and see my comment on their Bilstein dampers above!)
