The panhard rod on my Roadster greatly exceeded my expectations. It really tightens up the rear in terms of lateral control, but what I didn't expect was that it would eliminate torque steer under hard acceleration. This was transformed, and the rear is now controlled, acceleration is dead straight. I don't have anti tramp bars.
Oh on the subject of anti tramps. When the single anti tramp bar was introduced on the Roadster, the rear ply bulkhead template was changed to provide clearance. So when I examined my 2012 Plus 4, I couldn't figure out why there was an enlarged hole adjacent to the offside spring. I assumed that the guy with the jig saw had screwed up. Much later, I suddenly realised the purpose of this enlarged hole!
I wish I had the confidence to fit a panhard rod to my Plus 4, but the later fuel tank is much closer to the diff. So much so that when offered up, the clearance is minimal. I don't want to do this job and then find that there is contact. I'm assured it will fit, but my eyes tell me it would be a challenge.
