So I have the little mud flaps but I also have coils. What does that make my G4 - a bastard?? That's 'cause I didn't bother to remove the little mud flaps when I switched to coils. Best look for the bags/coils to be sure.
Oh, and I also have the little switch on the dash to raise/lower the SLS but it doesn't work since I disabled it when I did the coil job.
