These are 12” springs but still lack about 1.25” of full extension at the coilover due to suspension geometry and wheel combination limitations. The new springs are coiled about 8 more threads than they were before. The front end is noticeably easier to bounce now. At launch, the front end was dropping too soon so I adjusted the extension to 3 clicks so it raises up about right and stays there. Have to take slow mo videos to really see and watch what’s going on.
