Oh boy... :shock: Don't you just love confusion???? 
Addco's: The rear bar that they offer, IS a bigger upgrade!!!! Also Addco's do include their own urethane sway bar & end link bushings... For at least the front & the rear bar bushings. Not positively sure about the rear end link bushings.
Misc stock rear bar stuff: Stock OE rear bar is 15mm. Energy Suspension only has 16mm or 14mm bushings for the rear. Someone else suggested purchasing the 14mm bushing & enlarging the hole to 15mm (someone explained this in another thread). PST DOES NOT have a polygraphite bushing for the rear, only on the front. The only polygraphite item they have for the rear, is the control arm bushings. For my rear rebuild, I went w/ the PST CAB bushings, and the stock OE Toyota sway bar & end link bushings (both are CLASS E items, as of last year, don't know about now).
Rear bar size confusion.... The last part that you are talking about... If you purchase a rear bar from some of these "other" vendors that sell sway bar upgrades for RA Celica's, THAT is where the problem is!!! A upgraded rear sway bar for the RA Celica is basically the same size as the stock rear OE bar for the MKII Supra. This is NOT the case w/ the Addco's!!! These are ACTUAL upgraded bars for the Supra & not a Celica. HTH.
