I replaced my old springs with new stock height springs. I made the mistake of purchasing them on ebay. When I received the springs, they were just in a box, no paperwork etc. Since the suspension seem soft, I really dont know if I got what I ordered.
The car has the following, tubular arms, QA-1 TN505 non-adjustable shocks, QA-1 sway bar, replacement Moog 5370 coil springs?? (ID - 3.63", Bar Dia. - 0.64", Spring Rate - 357, Load lbs. - 2022, Install Height - 10.25, Free Height - 15.94, # of coils - 9.81, OD - 4.91") When I searched the Moog site, these springs does even come up for firebird. So they might not even be Moog springs.
So I am looking to replace the springs again, but this time replace with a stiffer than stock coil spring. Any suggestions?
