It’s a pretty simple install. Just take your time. I knocked out 90% of mine by myself in about 4-5 hours at a slow pace. The most time consuming part was cutting the original plastic, but it’s worth going slow to get clean cuts. The instructions that came with it were pretty ok as a guide. I didn’t have to do any grinding to get around the swaybar. I’ve got the KDSS.
Mine certainly sagged in the front after the install but I installed Bilstein 6112s up front and not only brought it back up but leveled it out. It also improved the ride quality in my opinion. I’m very happy with the setup overall.
