Hi, I put a set of 03 "new take off" springs on my 87 notch an they seem kind of stiff....I'm thinking the newer, heavier car had a higher spring rate...or am I getting old?.....anyway...are any of you running 4 cyl springs in your cars for weight xfer? if so how's it working...did u use all four or just the rears...i was thinking it might set too low in the front with them...thanks
