GT4RS - Availability, what’s the latest?

[ChrisW.]

With ten year bonds at over 4% and massive asset destruction in some significant parts of the World, I think that lenders will be in relatively short supply and probable interest rates will track higher for longer ...

More to the point, if this hangover for Porsche is bad enough ... just maybe they will learn a lesson.

They did not have to fuel the fire as they undoubtedly did ... though nobody would wish on them the supply disruptions of Covid and the war in Europe.

(Hence my preference for pre-Covid manufactured cars. Enforced short term component substitutions are invariably bad news in terms of both cost and reliability etc.)

My 2p.

I’m sure to drive this is stunning, but when you sit in it it’s 90% 2013 Cayman, the interior feels very dated compared to a 992 and is still really using 991 gen interior tech. Will there be a 718.2 or is it really curtains for an ice Boxster from mid year?

[ChrisW.]

I'm reading that 2025 is the end of the line for the fossil fuelled 718 ... this platform being the obvious Ev option particularly since the 911 can better withstand the likely fossil fuel tax premiums ... to the end of this option.

From the standpoint of frequent track-day practicality I was very surprised that Porsche opted for centre-locks on the GT4RS ...

Interesting move yes, but no less practical than CLs are on 911 Turbo S, GTS, GT3/RS and GT2 RS since 997.2.

Its a ‘premium’ feature.

Exactly. A premium.

Are the centrelock hubs 'lifed'? I really need to catch up. Can you put 5 lug on a 4RS, I've seen JCR go the other way on a 718 GT4.

In USA, a lot of 997.2 GT3/RS track day cars got swapped to 5 stud from centrelock and I am pretty sure, in theory, it's possible to switch either way.

In the real world, with a cordless wrench and 'normal' torque wrench, undoing 5 studs is probably just as fast and more simple that the bargepole-wrench and Rubix Cube sequence for centrelock. But, because racecar...

6k track mls for CL. As they just want to take premium product money from your pocket.

Tbf the 5-lug hubs have also. Just that nobody ever talks about it.

[Snowy999]

Thx Tyrone, yes the hubs are lifed for 981GT4 based on track usage too.

My 2p.

was there actually ever any supply disruption, or was that bs to drive up the market ???!

from what i see they delivered more cars than ever over this period!

[ChrisW.]

I know that my old company had huge problems with electrical components ... payment up front, contracted price blackmail weeks before due delivery despite 52 week lead times (from 26) ... and look at the current failure rate on certain now known issues ?

The whole supply chain was substituting ...

Of course there was a supply chain issue. Most of the ports in China were closed at various times, let alone the factories.

Any automotive production lines that had even the least reliance on parts from the Far East had to shut down.

In theory this could be as few as 30 very full track days ... but it's the convenience of being able to change wheels without special tools that is the main advantage. Having said that, standard large wheels with wide tyres are becoming very heavy !!

[TDT]

I do agree. Little bit more of a ball-ache.

i had my car up on the air for wheel rotation before a track day as couple of weeks back.



Easy job. No drama, no stress, no special tools… solo. No need to borrow a foot/leg to hold the brakes.

I hope you had something else on that corner in case the trolley jack failed, or the jacking point sheared off. At least you’re only changing a wheel and not putting your head underneath the thing.

I left mine in exactly that sort of position over a weekend. I did put an axle stand to assist the jack, just in case, but there was zero creep.

I am very interested in the portable scissor lift type jacks - Quick Jack etc.

can you use an airgun (is that the English word?) to change them
or do you have to do it manually? I guess manually to set the exact torque?

[ChrisW.]

For five studs I use a cordless drill with a variable torque setting to control snatch when the nuts are loose ... plus a wheel wrench and then a torque wrench (twice) when torque-ing up.

For centre locks Porsche suggest not using an air-gun. There is a rather expensive electrical device which can be used in place of a long bar to torque up centre locks ... it prevents counter rotation by locking against wheel itself so in this respect it's safe a painless, but costs around £4000 when I last looked.
