I am looking at adding offset poly steering rack bushings to sharpen steering response and reduce bumpsteer. I was wondering if the poly will significantly increase the NVH (will my hands go numb from the vibrating steering wheel)?
I used the HyperFlex bushing on my 97 Stang. WOW!!! They are great, and there is NO transmission of vibration up to the steering wheel.
I also put replaced all the other bushing on the car at the same time, the only ones I can complain about are the rear controll arms. They DO transfer alot of vibration, if I did it again though the improvement over the stock rubber was worth the little bit of discomfort.
