You are the dumb here. You wanted facts, I checked with professional and gave the answer from him. Yet you go mad and personal. Can't face the fact still? What else do you need? That is the part that we are debating here and you out of nowhere go and talk about the arm. Aiseh!

Talking to people like you have to use downgraded to basic English. Else, you would misinterpret and think aftermarket something else. Do you know what is swaybar?

You can go lift the BMW 5-series, Mazda 3/6, Lancer GT rear suspension METAL BAR (try not to use jargon with dumb KIASU like you) then you come and tell me how heavy. You think that Metal BAR so light? The so called lighter Torsion Beam one is not that light neither.

Then can you explain where the 50kg come from? The rims and wheels ain't that much big difference from 16" wheels neither. The spoiler? FYI, FF cars that wanted to improve handling, they would distribute more weight to the rear by adding more metal to the back. OK?

Yes, sway bar is anti-roll bar. Even the cheap aftermarket thingy bought from kaki motor or brothers is also called anti-roll bar that is real light and fit to Wira suspension. Avoid using the word anti-roll bar or sway bar seems it led to confusion to many. Just call the bone like bar in the rear METAL BAR for the time being. How many of you really remove the entire rear suspension set and try to lift with hands for real?

By the way, despite so many disagreement, how come none ever mention where did the 50kg extra weight in Lancer GT come from? Inspira & Lancer GL are actually at the same weight at 1335kg while Lancer GT at 1385kg. Back then people said its the bodykit which is incorrect. Then they relook to the chassis, they don't find anything different between GT & GL. Exhaust pipe, resonator, catalytic convertor and manifold also not that heavy.  Where else?

If you don't know anything about manufacturing cars, don't talk crap here. I suggest you to find out more with technical team before you reply. Despite so many specs Lancer, GT and higher only get more kerb weight difference. How come? You can't even answer that properly. Oh really, Lancer tyre so heavy? You ever put the 18" GT rim and 16" Inspira rim on the weight scale and how much the variance? Do you know what is alloy rim in the first place? Not cheap imitation rim you buy from tayar shop.
