Ride comfort in 430ix vs 440ix. Both convertibles

barclay · 04-02-2023, 04:36 PM

Hello,

Assuming both have 19 wheels and non RFT tires, is it the same or is the 440 stiffer?

Thank you in advance.

I would guess the same, assuming also that the 430ix is the M sport. Yes, the M440ix weighs a bit more but the springs are no doubt a different part number. If the 430ix is NOT an M sport, possibly a bit cushier ride, but I suspect the difference is quite small.

Does either have adaptive suspension? That makes a big difference from what I've read.
I have an M440i with 18 inch wheels and runflats and adaptive suspension. I think the ride is very good in any mode.

I believe no adaptive suspension in either but I would use Comfort pretty much all the time.
