Height difference between ACS Spring and original M Sport

Wilzay10 · 05-12-2013, 02:23 PM

I was told that the ACS Spring is about 10mm lower than the original M Sport spring. Should I keep using my original or go for ACS for just a 10mm drop? Will the handling also be improved?

Can someone pls tell me what I should do? Thanks!

Mine was an inch or more, but I have a 550i.

I believe it's 45-55 mm. A little over an inch. Makes a difference in stance and a huge difference in handling. Do it!

From my reading, I've learned there are other variables that affect the answer to this question (for future reference to other readers).

2013 M-Sport without DDC is .5 inch lower than a car with DDC
Dinan springs lower a car .5 inch (equivalent to M-sport without DDC)
ACS springs lower a car 1 inch (avg all around)
HR springs lower a car 1.5 inch (avg all around)

Here are the results for my 2013 550ix with DHP after settling (1/8")

ACS Spring Drop from stock:
Front: 1.5"
Rear: 1.25"

Stock M-Sport Springs Height

ACS Springs Height + 20" Morrs

ACS seems to be the perfect drop. Anything more would look too slammed on a car like this.

Gorgeous car Chili! Those Morrs and drop is perfect.

Prior to 2013, the ride height for M Sport and regular should be the same, right?

Thanks - I really think this is the perfect wheel/tire/lowering combination. (That's my opinion)

I never paid attention to the ride height of the M-Sport and non M-Sport, but I'm sure the heights are the same as others with non M-Sports have lowered their cars with ACS springs with the same results.
