Any of you guys put a track alignment on it? If I get back into this car I am considering just getting the alignment done right away and also changing the stiffness of the rear sway bar at the dealer to help with push I noticed on track.

…except Manifold has me thinking I should be looking at a Cayman R instead..🙃

Manual Cayman R is a fun road car, but 4RS will destroy it on track.

Apologies if this has been previously posted.Randy Pobst Pushes Porsche GT4 RS To The Limit : What Did We Learn?

we learned but we already knew that the rear rebound cannot cope, or the rear springs are too stiff. imo a bit of both.

Mr. Adair

Yet somehow it still broke the track record. It's all relative. When my driving ability catches up with this supposed terrible rear end I will worry about it. This was a world class driver pushing a street car to it's max. It's not a race car. It's a street car you can track. I'm still left wondering why these guys don't by Clubsports instead of buying a 200K 4RS and then spending another 15-20K. Many of my friends with more money than me are now buying 997 Cup cars to track. 80-100K and you are done.

Manifold

Running cost of a cup car is quite high because of need to rebuild the transmission and engine, plus you have to trailer it and can't enjoy it on the road. But a real race car is certainly better on the track, and also safer.

Watch Randy's hands. Most of time, his corrections in the corners are with one hand. He's not finding the car hard to drive. If he wants to change the setup of the car, it's to make the car faster, not because the car is hard to drive as is.

If I could buy a GT4 Clubsport and drive it on the street to and from the track, I would. Love that car, and everything it’s about. But as it stands, I don’t have space for a trailer and a hauling vehicle.

Guess the GT4 RS as a track toy will have to do! 😆

Mr. Adair

All correct. Running a cup car 6-8 track days a season will not require rebuilds and my main point is these guys are essentially building a Clubsport and I doubt very much these are cars they use on the road once they are modified this far. They surely have a dedicated street car at home. Remember, you also have close to a 100K to spend on ancillaries as a decent used Clubsport is 125K. It's just how I think about these things..

Manifold

People I know who track cup cars are typically doing way more than 8 track days a season, usually more like 20+, some a lot more than that.

Thought it was the fastest 4RS lap. which don't say much when a Pro drives it.

Mr. Adair

Yes, it was a 4RS track record. But it's also a street car. To me it's impressive..

Mr. Adair

Figured I'd put a little blurb together, specifically for @lilbza , as I was finally able to have back to back leisure drives with my recently broken in 4RS and my 4.5L 6MT 718 Spyder.
A little background on the Spyder for those not familiar: 4.5L DeMan motor + DeMan gears + DeMan catted headers/JCR full Ti + Drexler 50/60 diff + Emotion suspension/KW Clubsport 3way + Forgeline GA3R.
My 4RS is a stock WP car. Both cars are running Cup2 tires. Please excuse me if my impressions are a little bit all over the place, just typing them out as they come to mind.

- One car is manual, one car is PDK. Both have short gears. The Spyder has noticeably stronger in-gear acceleration and monsters the 4RS everywhere except when it comes time to shift (I can't defeat the almighty PDK hehehe)
- Spyder is more composed and settled over bumps in general, but this is especially noticeable during sharp compressions at low/medium speeds. At higher speeds, the damping of the 4RS seems closer to that of the Spyder, but never as smooth
- Expanding on above, 4RS feels noticeably stiffer even compared to previous 991.2 3RS and 991.2 GT3.
- Both feel basically identical in braking performance, no surprise there (both on PCCB)
- The sound signatures are wildly different. The 4RS is intake heavy, has the associated resonances bouncing around the cabin and shrieks at the top end. The Spyder is exhaust heavy, much deeper and somehow more serrated than the 4RS.
- Both have a bit of a race car lope at idle, which I absolutely love.
- Spyder smells more racecar LOLOL (Boostane).
- Seats are the same, interior is basically the same. Can't hear the audio system in either. Can still hear wife rolling her eyes though (strange how that works).

Happy to answer any and all questions about them. Overall, extremely happy and fortunate to own both...they are different enough experiences to me that it makes total sense keeping them side by side.
Will copy this post over to my DeMan thread as well.
