rear suspension mods ?

since i put a cage in my 82 stang it doesnt transfer the weight and launch as well , i already have 90/10s in the front and i took out the sway bar , im looking at trying to improve the 60 foot times , ford racing makes a set of lower control arms that lower the front mounting pionts and claim to improve traction under acceleratin,
i have also heard that softer springs work better ,
and i like the lower control arms that granatelli makes with the adjustable spring perches i think with a set of those adjusted up to get more travel with softer springs and an air bag for the pasenger side to keep the tire from getting frendly with the fender might be the ticket

has anyone tried any of these or something els ?

Stay away from GMS. All they do is make cheap copies of other designs. The GMS arms are based on the Maximum Motorsports pieces, which are very good. Also, the Lakewood Traction Action arms also alter the mount points to offer more traction.
