Weight difference between gta and formula 350?

I'm sure this has been asked before but I'm new to this site. So anyone know the weight difference between a gta and a formula 350? Thanks! We2man

Couple hundred pounds. The formula is one of the lightest birds, and the GTA is the heaviest.

I agree, at least a few hundred pounds, but depends on the options. T-tops etc add considerable weight.

From the 1990 Manufacturers Motor Vehicle Specifications:

FIREBIRD FORMULA W/WS6 - 3338 Lbs.

FIREBIRD GTA - 3554 Lbs.


Then there is the impact of all the various possible options.
