super stock springs

less air in the sky jackers would be best as not to bend any parts up top or down low where the shock attachs.
Also, there are front spring hangers on the market with 2 or sometimes 3 mounting points. If you choose the lower point to mount the springs, it will raise the car up higher, but, it will also rotate the center section and through the pinion angle off. Longer rear shackles can correct this. Not to much though, it isn't good to have long shackles on the back end for handleing purposes.
