I have used the southside machine lift bars on the street and you get a very harsh ride. You transmite a lot of driveline vibration to the car there are no rubber bushings like other models. They get an A+ for helping in the traction department even on street tires they help a ton! I just use them at the track. I love the way they help on the street but not worth the noise or stiffness, Just my two cents.
