Eibach Pro Kit (E10-63-023-02-22) or RSR Down Sus N009D?
I can't find the Spring rate for the Eibach's... wanna go for whatever is stiffer. I assume the RS*R is stiffer due to reduced ride height drop, but I obviously could be wrong.
Have the RS*R at $350 CND, and the Eibach at $298. Likely both sit around $375 after duty ( one from US one from Japan)
