Simply put I think it does for the front end what the rsb does for the rear. The car also seems to take bumps in the road better...not as harsh as it used to be.

I don't know what vibration people are complaining about....I can hardly notice a difference....and that difference can only be felt with the a/c on full blast

These are the same mm's that are used on the 4th gen's

Very noticeable mod

A+

 

its because you have an auto.. and its probably idling high.. if you had idle at 500 it would vibrate.. i think

 

Your right sprint at 500 he will feel it!!!but at 8plus it goes away!!!
