the ride on drop springs compared to coilover springs, are always going to be much better. I would encourage you to beef up that suspension with adjustable KYB's. so you're on the right path. as for your car bottoming out, thats normal with stock struts/shocks with a new drop. That the reason everyone replaces there shocks/struts when dropping thier ride. don't forget to post some pics. oh heres a tip, buy some spray on truck liner and coat the bottom of your body kit, or factory bumper and skirts. This will help with your car hitting anything when you park or go over bumps. whenever you're changing heights you never get used to how far to park in or how fast to coast those bitch bumps in shopping centers. I you also use the same coating to coat the inside of any fiberglass kit, it strenghtens it to prevent any type of unwanted/costly cracks and damages. spread the word
