Key area in my experience is the panel/void below the rear side windows and the two rear wheel arches. The Porsche trim piece below the rear side windows has thick rubber backing precisely to stop excess noise. Try driving without them and you will immediately see the difference.

Keep in mind that an enormous amount of sound is from the convex roof above your head acting like a speaker facing toward your ears. One area most people forget is that if you can dampen your c pillars- you remove a HUGE amount of interior noise. Without adding much weight at all. So if your headliner is out- work on dampening the inside of your c pillars and the tops of your rear quarters toward the back. And the area below the rear window.
If you need a comparison - drive a targa or cab with a g pipe or similarly loud exhaust. The difference is staggering.

Please take this as a serious comment, but have you considered getting a set of earplugs? A lot of musicians I work with have custom made ear plugs that are very comfortable and work incredibly well. It's a cheap alternative to all of the excess work and weight you're considering adding to your car. Even the throwaway ones Ive used when working in nightclubs and music venues are a godsend. I've even ridden my motorcycle with them in from time to time.

Wearing earplugs while driving is not only dangerous, it’s illegal in states like Massachusetts (you must keep at least one ear free). Listening to these cars while driving is not only part of the thrill, it provides critical feedback from the engine, tires, and brakes.

I drove her for 40+ miles today( my longest drive yet) and it was fine without the soundproofing. I’m sure it will be slightly better after the soundproofing...which for me will be perfect.
Just wanted to thank everyone for the input. I will take all your suggestions to my interior guy before I get it done in May.

Fwiw- the best ear plugs if you go the custom ear mold route, are etymotic research musicians ear buds. You can buy the standard buds in various amounts of noise reduction , they are acoustically correct, so yu are just lowering the volume. If you go with custom ear molds, they go farther into the ear canal and once at a certain depth, you have the noise reduction without the downside of normal ear plugs where you can here inside your head while you speak. The sound it totally natural, just lower volume.
As said before- it's not safe. But there you go. Use them on the track. (You should always have ear plugs on track anyway, or you end up old and deaf)
