My overall opinion? Form follows function.

An SUV is designed to ride high, it's overall concept is such that when you lower them you look unusual, some say freakish.

We began lowering cars to gain aerodynamics, lower the center of gravity...we also moved to larger rims to allow larger rotors...junior ricers have taken both these concepts- the lowering and larger wheels -well past 'what is needed' or 'what is useful' into the 'I want it extreme and in it's extremeness we find some kind of 'statement'...' Reminds me of the 50s where someone decided cars needed fins on the back...and a race began for the biggest fins! We just take a design cue and take it to it's extreme.... I digress.

Any car can be lowered. HOWEVER, not all cars can retain appropriate spring/suspension travel. It isn't just cutting springs, or getting stiffer but shorter springs. You may think it is...many people who are 'suspension-clueless' will buy only based on "it lowers 2.5 inches" Without taking into account the new suspension travel, damping rates and suspension geometry, I would not do it.

Modifying the suspension will surely cause BMW to deny any claims relating to the suspension, and they could claim that it impacts the driveline should you have a claim and they are feeling annoyed.

I have adaptive drive so no lowering for me...
