I'm usingt he Eibach ERS line of sprinsg all custom rated springs for Coilovers the race shocks I'm getting are going to have coilover sleeves with them so I just need to get the springs...

yes I could just get custom rated sprinsg form GC but the Koni Sleeves with ERS springs are cheaper then a GC sleeve and spring....

The other option I have is Tien HAs but I haven't decided yet as to what I'm going to do

Tein HA is just sucks compare to race revalve koni. it's a complete different story. the buddyclub is the best bang for the money. I am still deciding getting a set of buddyclub or spoon N1 damper
from my experience koni yellow still sucks. they can't handle over 500 spring rate...
