I currently have ET Streets on my KB Cobra. I have not had her on the track yet so I do not know if they will hook-up. I have just about every suspension upgrade there is and a solid axel. Should I spend the money and buy a set of ET Drags or will the ET Streets (new condition) work on a 630wrhp car? I'm hoping for 1.4-1.5 60ft time; launching at 4,500-5,000 RPM.
