.i cant speak on truck..in my case instead of tryin to match what i "already have" even tho i swore it was dialed at the time. i took the advice of others faster and more experienced that i trust and tried different springs to see how it affected the car and how it affected me driving it.And i feel i learned alot. Alot of people better than me are still using standard ae springs also, but i dont let that steer me away from trying to get my car better or more capable for me,,i invested less than 20 dollars to first put BB springs on my buggy..and it was one of the best 20 dollars i feel i have invested in the car..that did lead me to keep tryin to improve my car (cause for me it was working) wich made me want to have variations of springs so i could see how i like em.prior to that i just ran what was "meant" to be on there. im not sure if i know if my car "feels the way its meant too" but i know its way more capable for me than throwing it down with the wc set up sheet..makin improvments in my car and havin people come check my car cause the say it looks dialed has been one of the most rewarding things for me..especially if you worked hard on it but your right the day the AE big bore shocks come out and i buy those i will be a even bigger fool ahaha
