New setup seems great, have tyres at 32psi hot all round, very stable and predictible. It is my first Cayman so still getting a feel for it.

Few missed apexes!

Based on what other with 4RS have done the 991 camber plates work. They add camber and correct the caster....much better than just adding shims.
Lowering the car can also add camber.

check the post from Ehresmann:

Need Tarett front tension arms to correct caster https://tarett.com/collections/contr...87-981-991-718

Does the GT4 rollbar fit in the GT4RS?

I have a Heigo half cage from my GT4 and it fits the RS according to the manufacturer. Can't speak for any others made in the US.

Hello Cafe Racer,

Is that video data overlay from the Porsche Track Percision App?

I had my alignment done prior to pickup and the tech verified OEM adjustable caster on the RS.

Oh it comes with the parts I showed?

Or it can move within a certain range,.. i.e. the puck is offset and can be rotated?

I don't have any pictures. I trust the tech. I also had camber plates installed at the same time - see my other thread.

ah, top mounts/camber plates will have contributed to the caster adjustment then… in that case don’t need parts on the arm.

Are you planning on installing one in the 4RS? Pictures if you do please?

I would gladly have given up PDLS, FAL, PTS, and a bunch of other three and four letter options if we could have gotten the Porsche factory titanium roll bar on our US cars. ;-)

Contribution yes but even then adjustments are required.

yep. Filmed on an external GoPro. Imported. Then synced. Then exported. Not the smoothest process!
