If i already have M Adaptive Suspension, can i just change the springs to lower the car or i need to change the dampers too? If so will i lose the Adaptive part of it?

Any dinan, acs, h&r springs will work with the stock dampers. No need to change the dampers. You should be aware that some have argued using lowering springs without changing the dampers will cause the car to be bouncy and premature damper wear.

Not an answer to your question, but an observation from someone who has used 275s.

M3/M4 OEM tire size on the 437M wheels is 255/35-19 and 275/35-19.

This setup will not work properly with xDrive. The wheel diameter between the F/R is too great and will cause issues with the transmission. In my case, the transmission was not shifting smoothly and after further research,some references suggest to keep the difference in wheel diameter below 3%.

I went with 245/40-19 in the front to keep the % difference as close to OEM stagger as possible.

I have a slight rub when turning on the driver side front inner wheel liner where it protrudes for the side view camera and park assist sensor . I am lowered ~0.5".

This hit me this evening for some odd reason.

For the Car Techies/Gear Heads.

Are the Alignment, Camber, Caster, Cross-Camber, Cross-Caster and Toe same for F30 403m @ 225/40R19 and F80 437m @ 255/35R19 and their different ET?

If not, then it would seem F30s with 437m should be setup with F80 Specs???

As I do not know tech specs for both, I am throwing it out here for those gearheads that are into these numbers.

As F3x do not have 437m OEM, your response doesn't really help.

OEM for 19" F30 403m?

OEM for M2 437m?

OEM for M3/M4 437m?

Options I probably haven't thought of......

Continental DWS, 5P, 6 SC6 or something else?

Michelin pilot super sport - Front 255/35/19, Rear 265/35/19,

The wheels came of F80 M3 with 275 rears, wasn't happy so last month moved down to 265's which are much better.

Thank you.

FWIW, you are at least the second F3x OEM 437m owner I've read on forum state they ditched the 275 rears.

Was it comfort of ride or something else?

Btw, your car looks great.

Hey Thanks!

It looked to buggy like is that makes sense, also I am considering lowering springs, I am not sure if I am now, but car would rub on 275's, I urgently needed rear tires and I just closed my eyes and went for 265's, and looks much better, no obvious difference in ride comfort, and looks lower from the rear. I would not recommend 275's, My wheels came of a f80 m3 therefore has 275s fitted.
