I have Micheline P4Ss on my 991.1 Carrera S and F90 M5 Competition and can without reservation they are better than the Pirellis they came with.

Get whatever the newest N-spec Michelin is available in your sizes/for your vehicle. Not a fan of the OEM Pirellis on the 991s and Michelin is much better all around.
I also noticed that the Bilstein B6 are not much more than the B4 on Rock Auto, given that you are driving a Boxster, handling is probably a top priority, why not use the chance to also get an upgrade?
My 86 I\u2019m currently on cost me $14,000. After 4 years with it i have about $3,500-$4,000 worth of up upgrades. pads+ rotors
Here\u2019s where I\u2019m at after about a year of ownership. A few of these were just cosmetic fixes. I\u2019m at ~$540 total. Spark plugs, replaced with NGK BPR6ES - $20.00
Had the same issue with my 987.2 S, ended up upgrading to a GT3 master cylinder and brake ducts, giro disc rotors and RS29 pads. Obviously running decent brake fluid and change it regularly. It’s now great and can handle many laps of Oulton Park without fading.
I just finished a coaching session with my friends 992 Carrera S on some new Vitour P1's and was very impressed with how they handled 20+ minute sessions. The heat tolerance is probably the best characteristic, especially compared to the yokes! The P1 just doesn't fall off on grip like that, they are very consistent and don't mind the high heat of the track.
The pads work great, no fade for me at my skill level, even with a 40 minute session. Also work great on the street, with no noise or issues cold. However, I am using up about 70% of the pad in 2 hours of track driving. Particularly the rear pads, which are wearing noticeably quicker than the fronts.
I just had the worst experience with EBC redstuff pads. brand new pads, and the first time i put pressure on them - they fail - badly! overheating within 5 minutes of spirited driving in the mountains.
I'd advise against the RS4 altogether. They wear super slow but they heat cycled out after 100 runs for me. The RE71RS were still competitive at 150 runs. It's a great endurance track tire if you're looking for life, but as an autocross tire it's not actually cheaper per run and it's handling manners are generally terrible for the use.
