What sport springs to install on 440xi convertible

B58Quebec · 04-07-2024, 10:35 PM

Picking up a 440 F33 2018 next week. The gap between the fender and tire is pretty big and i'd like to atleast have it filled by 50%. This is a daily and I don't want anything rubbing. I want to keep 19in wheels for winter and summer. Would the H&R Sport Springs be a good buy? Should I also change the bumpstops for F8X ones?

My 440 has the M Sports Package with adaptive M chassis & brakes.
TIA!

While HR sport do give a very nice drop visually, the consensus seems to be that the ride quality takes a big hit with factory shocks. I went with an Eibach pro kit on my 340i xdrive and it was the perfect drop for my needs, which was removing the hideous wheel gap in the front and getting rid of the reverse rake look. Now it just looks like a factory RWD M Sport. Not sure if they make a kit for your car though. Generally speaking, Eibach pro kit, ACS, and Dinan should be the most compliant options with reasonable drops. I would get the F8X bump stops for whichever spring you get.

thank you. unfortunately i'm not sure if i have other options other than H&R.. the f33 springs seem to be very limited due to demand/weight i guess..
