Through some searching I'm getting mixed reviews on whether or not I should replace the front and rear sways or just a front bar upgrade is sufficient.
I am leaning towards the Hotchkis bar or bars since I have a set of their springs waiting to go on.
TO THE OP - Not trying to jack your thread just trying to see if the rear bar is worth upgrading.
