I recently put in a set of K-sport control pro coilovers and daamn they look good! The ride is of course not as good but the car is sooooo low! I been driving it for a little over a month, and I can't even go over speedbumps. such a pain.
Anyway, today something weird started happening. When i gun it (pedal to floor and rpm's to 7) there is a vibration coming from the rear of th vewhicle. This happens between 4000 and 6000 RPM's mostly (due to high power going through drivetrain). Does it alot in first gear, almost as bad in second and in third is hardly noticible. In fourth and fifth pretty much inexistant. I was thinking that it's probably my diff (I do have an LSD because my 325i is a Canadian one, and incanada we get LSD's). Also could it be the boots that go from diff to wheel?
Vibration is violent and is making me drive slow now. I don't like it. SOmeone plz help.
PS: For mods I have a SPEC SStage 1 clutch for M3 and a fidanza lightweight flywheel (also obviously for an M3).
Engine is stock. DINAN chip and catalytic converters have been cut out (HAHA NO EMISSIONS TESTING IN CANADA SUCKERS)
