BMW M3 Forum (E90 E92) - View Single Post - GC suspension + BBK installed. Need a bit of help.

ILLCOMM · 07-11-2012, 10:12 PM

I got my BBK installed today (stoptech ST-60 and ST-40) along with an alignment and corner balancing for the GC suspension I added last week (thanks KM3!).

Looks great. Couldn't be happier with that.

However, there is a significant "thump, thump, thump" from my left front under hard braking. Always present. Is far more audible than it is detectable through the steering wheel. Any thoughts? Am trying to bed in, but this feels like it might be something else.

Got a tight time frame as I go for a road trip to a 2-day weekend track session on Friday.
