Since it seems I will be buying new springs, which vehicle weight is recommended? What part number would it be on ebay? I usually order from there. I do not mind a rough ride on the street. Just want the best possible hook-up at the track.
The one's that are usually used are P3412002/P3412003, or the "002/003" springs as most people call them. They're recommended for a 3200lb vehicle weight. Maybe a little on the heavy side if you've done much weight reduction on the car, but they seem to get used the most for most A-bodies in street trim.
