alright before anyone starts, i've decided on illumina's with GC and custom extended top hats.

ok well i've read about the different rates and im getting confused. i heard you have to take into consideration the tire size you run. so long story short this is what im running and what im going for.

-primarily stock ef sedan, no heavy dohc under the hood
-195/50/15's
-staying dropped very low (yea yea i know i wont have THAT great of a ride)
-100miles freeway driving every week day for work.

so as you can see im mostly on the freeway which is (sometimes) pretty smooth and straight. i just want to be able to have a "good" ride, nothing spectacular but then again i dont wanna be hitting my head on the roof liner.

so what should i be looking at for spring rates? OTS GC's or should i call ahead and have custom rates? extra charge for that?
