IMO, with an elephant sitting on the nose of your car, 500# sounds light for a car that you actually want to drive without worry on the street. If this is predominately a street/strip car, than yes, they may seem a bit heavy, although they will improve your consistentcy.
.94 t-bars with a hemi @ 155# rate would be, IMO, too light. To duplicate that in a coil over may be 250-300# spring, again depending on motion ratio of the lower control arm.
But it is your car and you know your driving preferences better than us.
I'm new to the coilover deal, so taking it all in- thanks. I would prefer to get some
decent handling
(if I can use that term with the hemi in there/ not ideal). The 245/45/17 fronts showed up today along with the 285/40/18 rears. They look promising
. The 528 engine has aluminum heads, w/p, intake, etc. along with the fiberglass hood & front bumper, aluminum brackets, Viper calipers and chromoly UCA's & LCA's. I would think it could compare to an iron 340 and stock front components IMO. The 500# springs sound about right.
