Hi Scott.
Welcome to the board. The ARB mounted lights are IPF Super Rally 960's. w/130 watt bulbs. The rack mounted lights are 130 watt IPF MSR-800's.
I know you're joking about the weight, but I am thinking about getting new rear leafs. I've got full skids underneath, and after I get my steel replacement bumper/tire carrier on I'll be adding another 200lbs (w/tire) to the rear end.
The front end actually responds very nicely with the Bilstein shocks and heavy duty torsion bars.
