I've been tinkering with a quality, reliable and quick disconnect for a couple of years. Have an idea now but little time to work on it.
AFAIKAFAIK the Disco bar is very similar to the Defender, even with a 2" lift and extra long shocks the rear one doesn't make a huge difference if you have any weight on the back (which admittedly you have more of an issue with), the RTI of a RRC changes very little with the addition of ARBs.
