I removed the headlight tint this past winter, it was starting to peel around the two bumps. Taillights I replaced with OPT7's. I have LED lights so output wasn't too bad but if you have the normal one's it might be too much.
This lip comes with a different bottom cover since you have to remove the factory lip. It uses less clips than you start with. I hear ya on them clips though. I mangled a few getting mine off.
I have the ABS Dynamics Type R replica on mine and love it. You will have to remove bumper to install but it's a pretty easy install. Fitment was spot on.
