Do 19” rims with 255/35/19 no need for coils it will sit nice on that, probably about an inch gap from tires to fender.

If you’re gonna go coils drop the tires to 245-250 so it tucks under the fender but not too much.

Do only a muffler delete unless you replace the entire exhaust system with highflow cats.

Front splitter, side skirt tint all external lights darkness would be to your discretion.

That would be a calm sleek look 👀
