Lowering a car and then not getting an alignment immediatly chews the inside of the tires.
I got rid of my OEM suspension 2 weeks after i bought my car. I could not stand rocking back and forth ,and side to side everytime i changed motion.
With my JIC suspension it got as close to luxury with more than an added dash of sport.
If i could do it again i would probably get the TEIN coilovers.
All in all suspension can make or break a car and how you like it or love it. I like my LS with OEM suspension, not i love to drive my LS all the time.
The wording says it all.
