These ones? I figured it wouldn't, especially in my car. It already shakes and rattles like nothing you can imagine and is about as comfortable a driving a park bench.

 

mike hook me up!

 

I have a KB pitch stop and I would imagine this one is extremely similar in terms of NVH. The biggest difference I noticed was how loudly I could hear the starter motor. This shouldn't even be considered NVH, because it's a non-issue after the car is started. On the positive end of the spectrum, I felt like the car became less joltey when coming off the throttle.

Yes, from my research, the starter motor does sound more live as if in the cabin. Ive also read that the engine is a little bit more responsive because it isnt shaking side to side as much. I already have motor mounts and tranny mounts going in so Im planning on going another direction.

 

Bump!

 

Trade pending.
