The Comfort Kit was fitted to my M3W yesterday. My car didn't suffer bump steer as bad as others, but it was definitely there and I always seemed to drive with a Death Grip on the steering wheel.
The Comfort Kit has transformed the steering. Definitely no bump steer!!
I drove 115 miles of 'A' Roads home last night and it was an absolute delight. The Death Grip is a thing of the past!!
Its probably the best upgrade you can make to your M3W. Highly recommended
