NEW OLD Eibach Springs

[F3BZ]

not quite just a different color. here's side by of the eibach (blue) vs spax (red). the spax are identical to the FMS springs. the rear eibachs are almost a full coil more and slightly different coil spacing. the front eibachs don't appear to have any progressive wind at all. which is better? don't know but i'm working on a simple spring tester using a scissor jack and a digi scale. i got 4 sets of springs i'd like to get some hard #s on.

Counting them, the top pic shows the eibach (blue) has a coil LESS than the red but the spacing is significantly different. Bottom is same # of coils but spacing changes again (red looking more progressive).
