I wonder how gt4 would have changed with the high down force. settings in that comparison. The 3rs is the hands down faster car though. Both incredible cars.

Downforce and more tire...

But it is exactly that lesser aero and smaller tire that gives the 4RS that playful character most everyone seems to rave about.

This! You can't stick anything larger than 295, maybe some 305s, on the rear (space limitations) but once you try 265s on the front on a 9" wheel these cars have a big performance jump.

I and others run 305's now... but I do know not all section widths and tread widths are identical across brands.

Was there much of a change out back?

Yes, the rear track was widened by 4mm/side. Even on a GT4 with a squared tread pattern 295 tire like the Dunlop compared to the Michelin people have found that the fenders rubbed on the side walls when on track and under compression with not enough camber.

Interesting to find out that US GT4RSs do not have *** std but EU cars apparently do.

Mojonito

I beg your pardon, my US spec car has a great *** 😂

I know it doesn’t matter, but is it true that the leather interior is counterintuitively lighter than the base one?

Greybadger

I think the rear wing, front spoiler/diffuser and fenders are different on the 4RS compared to the 4RS Clubsport

Has anyone looked at swapping them over?

TDT

They are the same shape and profile.
Only difference might the used of nature fibre in the RS CS vs Carbon fibre in the RS

Where do you think you'd get the OEM RS Clubsport parts from? Likely need to be ordered straight from Porsche, and unless you have a Motorsports account for that specific model car its unlikely to be orderable for you.
