Well, I have half of that maximum motorsports setup. I installed the panhard bar on a few months ago and I am still very impressed by how it reacts into turns. It does what it is supposed to do. As far as the install, I took my time and rechecked everything before the drilling and tightening was done. It took five hours or so. I don't have exhaust clearance issues but some do so be ready for it.
I want to get the torque arm but not looking forward to the install. It is supposed to be harder than the panhard bar and there will be h pipe interference. MM says to change the spring rates after install too. I'm sure the TQ arm will help a great deal extra but I'm not ready to deal with the hassle yet. Take pics and post your progress as you go.
