My 2019 718 Cayman GTS PDK

A week has now passed since I took ownership of my 718 CGTS. Total mileage is still 494 miles, as I have done zero miles since last Saturday. My car is safely tucked away in the garage with the C-Tek charger connected.

In the meantime, I have been busy detail washing and cleaning the bodywork and wheels in preparation for my next door neighbour applying the Gyeon ceramic protective paint treatment. This is a similar product to the G-Tech alternative, and in my experience with having this done on my previous 718 CS, it really works. My last car was still showing robust beading of the water droplets on the bodywork following washing even after 2 years and 18,777 miles. Insects, road grime and brake dust simply washed off. Mike, my neighbour, will apply the Gyeon solution to my GTS next week.

Following that, I have my car booked-in for the application of Xpel PPF on the door sills, rear wheel arch areas, bonnet, and front bumper. Road rash and stone chips are always an issue with the Cayman. Unlike the 987, Porsche do not apply a protective clear plastic film on the side panels ahead of the rear wheel arches on the 718. With a wider track than both the 987 and 981 models, plus the 8.5" and 10.5" alloys, the tyres spray road grit like a shot-blaster on the sills and rear wheel arch panels. This is may not be a big issue for those owners whose mileage is mainly on motorways, but for where I live, rural roads are frequently spread with a mixture of salt and grit in the winter months. This grit lingers on at the edges of the road long after the winter is over and gets washed across the road when it rains. So, in my opinion this is an essential requirement on a new Porsche in this part of the UK.

I have not as yet fitted the Zunsport grills to the front outer side air intakes. I've decided to leave the grills off until I have a few more miles on the car and have the temperatures fully monitored in all driving conditions. When I was detail washing the car I had a good look at the front radiator intakes. Both the central and side intakes on the front bumper on my CGTS show 3 very exposed radiators wide open to the elements. Whether this is exacerbated by my choice to fit the optional Sport Design front bumper module is a moot point. On the plus side, at least the intake apertures are very easily cleaned of accumulated debris. My main worry is stone damage, not the accumulation of leaves. I'll keep my eye on this topic over the ensuing months.

After I have the paint treatment and PPF applied, I can't wait to get my car on the Highland roads to the Isles in the far north west. This is dream country for a Porsche and at this time of the year when the roads are empty of tourists it is is an exhilarating driving experience. My plan is to do several day trips over the coming weeks to Achnasheen, Kinlochewe, Gairloch, and Skye. All of these trips are an easy return day trip from where I live, and will help to settle the suspension prior to having the wheel alignment geometry adjusted to my preferred specifications by my local Michelin specialists GT Tyres, in Forres. My first track day experience with the 718 CGTS is Oulton Park on March 8th. Only then will I know the true comparison in performance compared to my previous 718 CS on a circuit I absolutely love.

In the meantime I leave you with a few photos courtesy of Paul Barlow, who along with Andrew-CS, joined up with me for part of my homeward trip across the Old Military Road.

The Old Military Road is an absolute favourite in Scotland, one we have included in several tours over the last few years. And that first picture shows just why!

Brian, my sales person spoke to the Porsche GB Product Manager for the 992 today and queried the Power Steering Plus on my behalf. The info back was that it was primarily a low speed aid for parking on the 992 though it may have a slightly firmer feel at higher speed. This, of course, could be quite different to your car. Then I checked back and noted that I had it on my 991.1 and not on my 991.2 and for the life of me cannot remember any difference [:)]. I don't remember it being an option on the GT3 which was quite another experience...

 
Hi Brian,

A few observations after following your `rear end` [;)]

The car`s appearance is extremely squat and purposeful - the brake light / indicator interface is good i.e. `clearer than most` definition when in use together.

The exhaust note is much `crisper` than I recall .... re. earlier 718`s

Let me know when you plan to visit GT Tyres, I may join you ... it is a year and 9,000 miles since I had the N0 PS4S`s fitted / geometry set by them. The front setting has maybe `drifted` as back then I experienced little or no `crabbing` on lock, this has now changed with them at 6mm unless it was down to their fresh, unscrubbed condition ?

Peter,

For my purposes Power Steering Plus has two significant advantages on the 718.

Firstly PSP does provide additional power assistance when parking. With my right hand grip impairment this feature is very helpful and I must say the principal reason I chose it in the first place on my previous 718 CS.

Secondly, as a keen and experienced track day driver, I was very impressed with the additional weight and road feel at the steering wheel rim provided at high cornering speeds on the track. If you don't do high speed cornering as on track days, then you probably wouldn't notice any difference in steering feel with PSP.

Brian,

It was a pleasure to accompany you for a few miles, along with Andrew. It is indeed very hard to find a reason not to drive the Old Military Road!

My thanks to Paul and Andrew for taking the time out last Saturday to share the joy of driving the Old Military Road in sublime traffic-free conditions.

Following on from Andrew's comments on my car, I would venture to say that Porsche have tweaked the damper and spring settings on the 2019 GPF evolution of the 718 CGTS. I have already mentioned the re-mapping of the PASM whereby in "Normal" mode the ride is definitely firmer. My first impressions of driving on the Highland roads are of a car which feels absolutely planted on the road. My previous 718 CS had identical sports suspension, lower ride height, and the same wheel and tyre combination as my new GTS. It also had the same smaller diameter GT Alcantara steering wheel, so by all accounts the two cars should have felt much the same on this particular journey. So, it came as a surprise to me that the new GTS seems even more focused than my previous CS on roads such as the A939.

Regarding the exhaust note, I have noticed that the GPF 718GTS sounds different, in a good way, from my 718CS which also had the Porsche Sports Exhaust (PSE) option fitted. During my detailed inspection of the car at home, I took photographs of the exhaust mufflers, albeit restricted by not having a ramp to raise the car. I could swear the mufflers seemed smaller size on the GPF PSE compared to my 2016 718CS. I will verify this when I have the car on the ramp at GT Tyres for the geo set up in a few weeks time.

Suffice to say, it seems that Porsche have indeed applied evolution improvements to the latest model of the GPF equipped 718 CGTS.

Brian, I have XPEL PPF (Applied by Topaz) on both my 991.2 GTS and my wife’s 718. I also have Gtechniq Crystal Serum and EXO coatings on top of the PPF and rest of the bodywork which is the recommended way of doing it by Gtechniq. Their FAQs specifically state that PPF will not adhere effectively to their coatings so I would imagine that’s the same with Gyeon.

Apart from the issue of adhering to the paint surface, if you think about it logically you want the PPF as the protection barrier for the paintwork and the ceramic coatings to enhance the gloss and make it easier to wash. With the coating put on last you have the ability to keep it topped up.

Good point Adrian that is my understanding as well, you may need to do some paint correction before applying the film dependent on your cars finish. The ceramic coating then needs to be applied over the film.

 
Adrian and Geoff,

I take note of your comments regarding the application of the PPF, followed by the Gyeon paint coating. On my previous 718CS I had the Gyeon paint treatment done first, followed by the PPF on the sills and rear wheel arches as this was an afterthought when I realised the vulnerability of these areas to road rash. The PPF areas were then recoated with Gyeon afterwards. It worked well. However, this time around I'll take heed of your advice, PPF first, then the Gyeon coating, as you have suggested.

Ralph,

Regarding the rusty welds on the mufflers, I'll email a photo to Chester and have them check it out. I honestly cannot remember if the mufflers on my previous 718 CS had the same appearance when new.

Brian



 
On the topic of the above photo of the rusty welds on the rear muffler on my car, does any current owner of a 718 GTS Cayman/Boxster have a photo of their left side exhaust muffler for comparison.

Any 718 GTS for comparison will suffice, particularly interesting to compare would be pre-GPF September 2018 models.

I wouldn't be too worried about the brown 'rusty' appearance of the muffler boxes.

Just looks like burning of the adjacent steel from the welding process.

I'm guessing it's stainless, some pickling paste would have cleaned that down nicely post-weld. Although as it's not a decorative or aesthetic part, the exhaust manufacturer may deem pickling and dressing unnecessary.

Some Britemax metal polish should clean it up.

The welders dont clean the parts which do not show. As quoted: If you want to polish it up then thats an option. If it's s/s then the welding rod is also but remember the name is stain less not rust free.

Helpful comments, thank you JMR and Ray. I'll hold back from raising the topic with my OPC for now.

In the coming weeks, I'll have a go at cleaning up the rust marks when the car is on the ramp at GT Tyres. (With their permission of course).

I would still find it helpful for a photo of a pre-September 718 GTS left side muffler to compare it with my photo posted earlier.

I'm speculating that the dimensions of the mufflers on GPF equipped 718 GTS models has been reduced. If this is indeed the case, this would not only alter the exhaust note, but also facilitate a change in the tail pipe exit configuration and rear diffuser design on future 718 evolution models.

Even at 70, I'm not averse to crawling about under cars. For the thick end of 50 years I've spent more hours than I care to imagine lying on my back staring at mechanical bits and pieces at close quarters.

Today was no exception. Heeding the advice of thread contributors JMR and Ray, I decided to tackle the rusty welds on the mufflers in my own garage. Armed with a Brillo pad, a container of warm water, a used kitchen scouring pad, sundry cloths, and my old faithful Autosol metal polish, I set about de-rusting the welds on the mufflers. Apart from complaints from my aching bones, access to the mufflers was extremely easy. Everything else was so clean with my car having done 500 dry miles. The job took me an hour and a half tops. Hopefully the Autosol will protect the rust from reforming for while. A photo attached for your interest.

While under the car I examined the GTS exhaust system carefully. No sign could be seen of the GPF filter, it must be tucked away close to the turbo installation. From my memory of examining my previous 718 CS exhaust system, this new GTS exhaust definitely looks different. The mufflers are smaller and the pipework leading to them seems of a larger diameter. This is why I am very interested in comparing pre-GPF 718 GTS mufflers with the units currently fitted to my car.

Looks better now Brian, well done.

How about these on a 993 from a recent regional visit to our local OPC?
