Just saw your contention re: springs.
Sway bars will help MORE than stiff springs.
On the Cobras, they actually have SOFTER springs than the GT, but they have a LOT beefier swaybars.
GM has done this for years, and in the 80s the Camaro would out handle Porsche 944s with soft springs and stiff swaybars.
The soft springs keep better contact with the road, and upset the chassis less -the sway bars keep the car level and lets the suspension do its work . ..
Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
