Wasnt able to get a track alignment before I picked up the car unfortunately and I felt it really needed it from experience last year. Observations:

For reference, I alternate between intermediate / advanced group depending on the club I run with.

1. Dunlop tires WOW. Like much better than Cup 2! Hardly any wear and delaminating with a long high speed track day. 80 tread wear! Very sticky. Opposite of what I was expecting. I was a big Michelin fan boy before.

2. Stock alignment not great for track. Def need this fixed. Less tire pressure in front seemed to help the understeer. Car pushed a lot. Needs to feel more “911”. Careful with 2nd gear throttle. Rear will spin! And typical cayman, hard braking gets a wiggle in the back!

3. High temp brake fluid seems needed even for a couple track days a year IMO. Felt some pedal fade.

4. Sorry everyone but LWB….i feel like I am being thrown all over this car the LWB seats do not hold me in. I actually think the 991 18 ways were the best (and better than the 992 18 ways) in my previous GT3s. I am not about to cut up a new car to put a roll bar in as it will only see a handful track days a year. Compromise to enjoy the car stock.

5. Car was flawless… but I must say I may have had 50-75% of the fun in a lightly modded BRZ to work on more car control. My instructor said he much preferred the 4RS over recently driving a 2019 3RS. I let him drive it for a half a session. GASP!


Enjoy your cars. Take them to the track. Life is short. Car feels slightly underwhelming on street driving.

With a proper db meter, the 4RS doesn't have 116db at all. My last car exhaust at 3 meters marked 107db, and it was unbearable to me, no hay the 4RS has even the same 107db

Anything you can do to mitigate loud noises throughout your life will pay dividends when you get older. As stated earlier, the effects are permanent and cumulative.

every review has the car at circa 104 to 107 DB. it's f4cking loud, you have not been above 7k revs yet !

MY iphone in 10 years has never trigered a noise alert !!! it does every drive out in the 4rS !!

you also messure the exhaust at 3 meter away, the air induction noise is louder than my exhaust and is a few inch behind my ears !!! I find it totally unbarebale when on it.as do every one who's been out in it.

thats Why i also have to lol at anyone fitting an exhaust or over axel pipe to a 4RS. why ? you cannot hear it, so you are doing it to be an asbo **** ? plus then no track days either then.

https://youtu.be/H6Mj5wchz-o?si=nYmSh2FxMoGAB1-o my 116 db is low look here "

LOUDEST CAR IN THE WORLD!? Porsche GT4 RS does 120dB at TOP SPEED!"

harry also got 116db like me.

when exposure to sounds is not good for you above 85db for long periods , who cares if the readings are 106db or 116db or just even 95db ? these numbers are way above the recommended 85DB limits proven to cause hearing loss. Any one saying other wise sorry to say is being a bit Pedantic, for what gain ?

I have just tested my cheap digital one vs my higher end hi-fi analog one it does read 7 db higher which would make my 4RS 109DB inside with my hi end one lets say give or take 5 DB :-) thats still 104db , it's just hard to use that one while driving due to being a needle type and not able to keep a peak setting. the numbers are meaningless really hence my pedantic comment, I bought a digital meter to record a DB drop when testing how to make it more livable in the cabin on longer WOT runs.

The 4RS IS loud inside and high pitched, some might love it. it hurts my ears on track and on longer runs when u are driving like mad man for 5 hours over taking cars and hitting >8k often it's very tiring and imo a serious health issue long term for my hearing. I am not willing to live with it or take the risk hence trying out things to drop it a few DB at least.
I think the higher pitched noise is far worse than just being "loud" and people do say the non WP cars may not do it to the same degree.
