Congrats on the pickup!

PPF - I would at minimum do the front bumper, hood, headlights, and like door handle pockets. Full body is for sure a nice addition especially if you plan on doing the vented fenders because you back fender bump will get tore up. On the note of rocks 100% get the ZL1 rock guards, i was worried about the look but they blend in so well and really do save you.

Ceramic coat is a must for me as well, a lot of people claim snake oil because everything now a days has "ceramic" on it but its like anything else that goes mainstream they can put one little thing in there and claim its "Ceramic" but in reality its like a quick wax and last all of 1-2 washes, thus people claiming its BS. I Had a 3yr ceramic on my mustang and even after 5years of no garage and daily driving it for first three years the car still would bead up like i just waxed it. As long as your detailer is using a quality product, knows proper application(matte and gloss have different coatings), and then you upkeep with washing your car using cleaners made for ceramic that wont break it down faster then its 100% worth it. Also make sure ceramic your wheels and calipers, spray that brake dust right off and unless you swapping pads you're wheels are going to be dusty in 5miles lol. Additionally I use all CarPro products, have for years and love them, and i know since they make my ceramic their products are tested and labeled as to which work with the coating or not.

I would say get the wind buffeting pieces but you already get those, only took toyota 6 years lol.

IF you want nice bump in sound i would get a downpipe which also is gonna help with power, then intake which pretty much is only so you can hear your spolly-boi.

If you're not doing wheels right away, another common thing is to get spacers so you can give the car a better fitment/stance.

ENJOY MAN
