2012 Camry rear spoiler installation
 

If you want to put a stock spoiler on your 2012+ Camry, it's a pretty easy job but they don't mention that you'll need an 8.5 mm drill bit and a 9.0 mm drill bit for the trunk holes. I visited and called the local hardware stores and no one had metric drill bits. One guy even told me that nobody makes them. I had to order them online.
Once I got them and got a copy of the Toyota instructions (also not included in the kit - wtf), the job went smooth and I was done in an hour.
I have the installation kit with bits and instructions for sale in Classifieds.
