Does anyone have a link to the XLS pictured in the screenshot above? I'd love to run some numbers on my car.
I have a 79 L82 gymkhana / F41 optioned car. I've replaced the front 550lb spring with adjustable QA1 semi-coilovers with a 450lb spring, a 360 lb old VB&P rear mono-leaf; I've kept the original 1 1/8" front swaybar and added energy poly bushings and moog poly end links, and in the rear I switched to a 9/16" BigBlock rear bar with stock style end links and I'm curious where the numbers end up.
I also don't remember VanSteel recommending a 3/4" bar with the 1 1/8" bar for cars with 275mm or less rear tire width. In my recollection they didn't step up to recommending a 3/4" rear bar until you end up with much wider tires, but my memory could be wrong.
I don't have a video on replacing the rear sway bar, but I could make one. -It really is about as simple as the AIM diagram makes it, though. -Pressing in a poly sway bar bushing is no fun, AND you really need to keep the metal collar / cylinder that goes around the endlink bushing (5Z in the AIM) because, AFAIK, you literally can't buy them anywhere in the aftermarket. -Unfortunately I damaged mine trying to get the end link bushing pressed into my stock end link bracket and had to used washers as additional spacers to take up the slack.
