I have recently purchased a Midstates Cobra and in the little bit of driving I've done it seems to easily bottom out. Believe car has the standard Midstates/Shell Valley setup(Qa shocks, coil overs and nine inch rear) using 350 front and 250 rear springs. Since I intend to get the car corner balanced and aligned can anyone make a suggestion ie 300 lb springs in the rear, or longer 250 springs? By the way the car is a 351 small block.
