Whats the difference between the two spring sets? Do they both lower the car more in the rear than in the front? The only thing I've found is that one set is blue and one is black...

The color is the only difference. Both sets carry the same Eibach P/N.

Umm, they are not the same... or shouldn't be when looking at this http://www.ravensblade-impreza.com/modifications/suspension/spring/spring.html


This shows the difference in reported spring rates, and that the rear springs are not progressive with the SPT springs.

the SPT springs are similar to the P1 springs, and the Pink STi springs (not in production anymore)

Or, i could be totally wrong...

but i think i'm correct.

The SPT springs are not progressive, but Eibach is the manufacturer and vendor for SOA.
