    H&R sway bar hollow?

    Guest-only advertisement. Register or Log In now!
    I am looking for a front sway bar for my RS3 and the H&R is 27mm. Is that hollow? I believe the oem is a hollow 24mm bar. Most of the other aftermarket brands I see are 25 mm, so I wonder how much improvement 1mm would be.

    some lager diameter bars are hollow to save weight.
    there is V little torsion (resistance to twisting) produced by the inner portion of the material.
    solid are generally cheaper to make.

    the H&R bars are solid and will add a few pounds. The diameter of the bar doesnt always determine stiffness, other factors like material and manufacturing play a role. We have had no complaints with the H&R or Eibach bars we sell and i actually have H&R bars on my 996 carrera. They offer a noticeable improvement in cornering and reduce body roll without causing any harshness or bumpy ride. Just make sure to use the grease for the urethane bushings or they will creak and squeak and make you curse.
