Hey guys, to those who installed H&R Sport springs on F30 xdrive models. Try this....go into a parking lot where there are no other cars around and turn to almost right lock while applying moderate throttle. Do you hear a sound that can be described as "wirring", almost like something continuously lightly rubbing?

I've had my H&R springs on for over 2 months and I only noticed this while taking a sharp freeway off ramp at higher than normal speed. I went to see a performance alignment shop and he suspects the angle of the front drive shaft might be a hair off with these lowered springs which is causing the noise and asked me to contact H&R. He said to be sure it's not the springs put back the original BMW springs and check.

Since winter is fast approaching here in the northeast and with the M performance lip I would become a veritable snowplow I changed back to the original BMW xdrive springs and now the noise is gone.

Hopefully this isn't a general production/tolerance issue.

I once tried cornering (to the right) really hard and fast on-ramp towards the highway on a long wide turn and did not hear anything.

I will keep an eye for you and post back if I hear anything.
