Progress Springs?

AceSyper has a set of Progress springs with a 2 inch drop. brand new. He said he'll trade me for my tein s-tech, also brand new.

Which is a better set up? I plan to use these with tokico illuna struts.

anyone?

Tein

anyone else?

More info on the tein S-tech i'm not to familer with those ones. But the progress springs are probaly the nicest springs i've seen from a racing standpoint. The rates on them are really nice and give the car excellent balance at things like autox.
