Oh yeah, I forgot to mention that problem too. I know exactly which part it is. I had to bend mine back to 90* with the regulators installed. With some creativity... i managed to.
and yes yes they look really sharp w/ the windows down. Plus the rear seat passengers like it. I hate being stuck in the back of a coupe when the windows don't open (or open like a Suzuki Jimny's rear windows as in the E46 3-series... come on now...) - at least when everyone else up front is enjoying window down motoring.
Anyway..
congratulations!
the 333hp M3 can't roll all its windows down... *taking cheap shots...* - just joking, I guess a 'race car' like the M3 can't compromise chassis rigidity for stupid rear quarter windows...
i just miss my coupe....
