who makes custom rate drag springs that will fit for QA1 shocks. Our current set up we netted a best of 1.54 60''ft, thats with KENS KUSTOM CHASSIS rear end set up and with next full-body race coilovers. This pro 4 car runs on 26''slicks up front and achieved consistent 1.5 60'' with no traction bars. We want to get the car into the low 1.4 60'' with the new QA1 shocks we got. To many companies to chose from eibach, tanabe, progress, full-race, tien, skunk2, any suggestions? I will post a pic of the QA1's as soon I get a hold of a digital camera.
