Hey guys, i also saw the video of Racebeyondmatter and got attached to try this. I ordered two springs on aliexpress (only retailer for this kind of springs in germany). I ordered the second stiffest green one 14mm x 55mm (exact inner loadcell length) and the stiffest brown one 14mm x 55mm. I will test both and compare to bpk, which i used before with the damper kit.
