I did full Xpel PPF with ceramic coating on top, the ceramic makes cleaning the film easier... For removing track rubber I recommend Mothers R3!

 

May be difficult to photograph and explain but any pictures or description of extra pieces of PPF applied behind front wheel/fender well would br helpful.

 

you're on the right track and that’s an excellent plan

since you’re tracking the vehicle, the film will need replacing more often than a street car, so I’d recommend pattern installation with sufficient extension for ease of replacing

for film choice, you’ve picked two great materials, can’t go wrong with either

at some point, XPEL/Suntek/STEK all are great materials made by actual companies specializing in ppf…better than the sea of alternatives that simply have the material private-labeled and not their core competency…there are a few exceptions to that, but very few

just make sure you find out which SPECIFIC film is being used. I can’t tell you how many times I ask clients that want us to redo their ppf work from other shops and they don’t have any idea what material it was…they’ll just say “it was XPEL, do they make other films?” Each manufacturer has a low/mid/high level material but many consumers never ask the installer which specific film is used…they’re more concerned of the brand name

Best advice I can give you is find the right installer that knows how to execute on a 4RS…it has its own unique challenges and you’ll want someone that’s familiar with the shape

and DEFINITELY get ceramic as it’ll help with rubber sticking to paint and ease of cleaning

hope that helps
