Well, I'm running the arms, but most are not.
The arms did restore a livliness the rig had lost since the change in castor, and ideally the pinion angle will be appreciated by my front shaft, which will vibe less, last longer etc etc. The growth in wheelbase is so minimal, however even a 1/4 here matters, I can 'feel' it, money aside, good mod. If youre just starting out with mods there are plenty other ways to spend it, OBA, Diff guards, Roof,roofLights,under chassis lamps, Battery, Tires, Wheels, Interior wiring, Stereo, hifi speakers, amps, subs, bluetooth, Bilsteins, Bumpers,sliders,winch, lockers, HD axles, CVs, were all stuff i had already done, so radius arms was pretty far down on my list, but yes, it was there, and its done, and I'm glad. Kudos to RTE for a neat mod. I do dig the QT lightweigt and all, but this is a component that playing with grams vs strenght may not be smart. The RTE stuff felt heavy, but indeed beefy, very HD.
