I've been looking around for things here/there and noticed that trunk lips usually go for around $100

$37.99 + free shipping? hmm..

Those two trunk lips are not legit, despite them using a TL in the picture the trunk lip will not look like the factory one. Here is where most people get their trunk lips from and looks just like the factory base/a-spec spoiler. I got mine from the link I posted and it looks great!!
