theres a company on ebay selling super lightweight radiator supports (square tube type). search lightweight g body support. im pretty sure its around $200, but saves a lot of weight. definitely lose the front bar if you're only going straight and the big axle mounted ARB's work great, but are pretty heavy. its more work to install, but wild rides race cars and TRZ motorsports sell really nice weld in chassis mounted ones that are pretty lightweight. ran my regal around with no front sway bar and QA1s with 250lbs/inch springs in the front. it's pretty bouncy, but as long as you know the cars limits it's fine. going through the same thing right now with mine, the dash isn't even going back in. just gonna make a switch panel and gauge pod to go onto the dash bar of the cage. its an addiction that consumes my every thought, lol. other things i can think of (not sure if you already have em yet) are aluminum bumper brackets, aluminum radiator, lose the tailpipes, bullet mufflers, fuel cell, light weight wheels, switch to a 2.5" coilover spring in the rear, aluminum seats/brackets and aluminum brake calipers/lighter rotors, aluminum drums. EVERY little bit helps!
