I have ATR stock height rate springs all around, i did a a-arm swap (BMR's) an it dropped the front an inch. I then tried some ebiech 1" drop springs all around..The Ride suffered alot, Went all mushy in handling,they where even sport springs!!. I like super stiff ride for cornering an high speed HWY romps,i run AK series Bilsteins. i changed out the rate/progessive springs for sport set, i lost firmness..they weren't in my car for week before i swaped back,I sold them to buddie with 1/4 car an he loves them..I'll be going QA1's or air ride next. I want adjustiablity in height..If anyone knows the spring pressure of ATR rate springs,I'd like to know so i can get the same pressure on inch lower set..
Enjoy!
