I am trying to get my suspension going in the right direction for street/light drag use. I have gone with so far... Ebach Prokit springs, strut tower brace, K-member brace, upper and lower mac control ams, 3.73 gears, alum. driveshaft, 225/45 front 245/45 rear tires. I am thinking I need upper & lower battle box's, and subframe connectors for now, what else should I be thinking of for the suspension?
