Gn's are regals. T types are regals. Gnx's are regals. 86 gn's had alluminum bumper supports. 87 gn's had steel. The steel was substantially heavier. The fact that a gn came with a 29.5 lb steel wheel per corner added weight. The T wheels were roughly 10 lbs lighter per wheel and alluminum. T types/ Turbo T regals did not come with spoilers which adds weight. WH1 designer not included as they came with spoilers. Only regal that did outside of the gn. Outside of that options played a roll. My 87 Turbo T was a factory lightweight car. No power options, roll up windows, manual locks, etc. That is the biggest factor in weight. Even with all that they are still land yachts.
I know that the rear axle and suspension on a turbo car is much heavier than a N/A regal. I've moved them by hand and there is a big difference. It's a much better piece though.
