So if I’m changing from 18’s to 19’s F40 M135i do you need to update anything , I heard you’ve to update software, do you really of just update idrive or is it a load of rubbish.
I’ve changed wheel sizes before on B,M,W.s before with no updates or issues.

Just ensure you reset the tyre pressure monitor after the fitment of your new wheels (and having a play around with your desired pressures of course) and you'll be good to go.

I’m looking to change down from 19s to 18s! Looking for a better ride quality and don’t think the 18s look too bad! Regret not getting adaptive suspension too

I lowered the car and think it looks pretty bad with 18’s hence going for Motech 19’s with Michelins P4’s . Hopefully look a bit better on the 19’s . Find out tomorrow 😂

I actually think that looks alright! My main gripe with the 18s, and why I went 19s initially was that they look much skinnier from the back which just makes the car look less muscular/purposeful on the road.

Which front lip and side skirts have you got there? Maxton V1 front and 3/5 side?

I went for V1 front , V3 side and rear diffuser with Genuine spoiler . Eibach 30F 25R springs . Drives quite nice see if the 19’s make a big difference to driving .
