Hi Everyone,
I am hoping that someone will know better than me how to diganose the problem that I'm having with me car.
I have a 2005 BMW 330ci convertible that had some vibration in the steering which is most noticable at speeds of about 40-55 mph.
Since that time I have done the following:
Brakes - All 4 wheels received brand new rotors and pads.
Wheels - All 4 wheels have been replaced with Motegi DV5 Racing Wheels. I went from the OEM 17" wheels to 18" wheels.
Tires - All new Pirelli P-Zero Nero tires 225/40 R18 in front and 255/35 R18 in the rear.
I also had a 4-wheel alignment done and all 4 wheels balanced.
Having done all of this unbelievably the vibration is now worse instead of better. I am at a loss as to what to do at this point. I hate to keep spending money aimlessly but have no clue as to what else can be checked.
Could one of the wheels be out of round? Even so, the OEM wheels were completely different wheels and I still had the problem so that seems like an unlikely scenario. Anyway, I am open to any and all suggestions. Short of that, the only thing I know to do now is to have BMW do a thorough inspection to identify the issue but I sure hate to go that route... cha' ching $$$$.
Thanks for any and all help!
