6 years and several modifications later - a 718 GT4 "Wolfgang" update...

Hey all,

It's a quiet evening here in Chez Twinfan as Mrs Twinfan is working job #2, so as I've been to my OPC today I thought I'd give a quick update on the adventures of me and my Racing Yellow 718 GT4 Cayman - affectionately known as "Wolfgang".

For those who don't know, I've owned him from new (delivered in mid-March 2020, a week before the first COVID lockdown!) as I was fortunate enough at the time to get an early allocation. In fact, Wolfie was the third 718 GT4 delivered to my OPC. Wanting a car with a manual gearbox certainly helped to bump me up the queue as PDK would not be offered until a year after launch. Aside from the Spanish gearbox, he's an almost fully loaded Clubsport car with the exceptions being:

* PCCBs - too expensive to replace, are at risk of damage, and after having driven PCCB cars I personally felt they offered minimal dynamic benefit (YMMV of course!)
* BOSE - I hardly use the stereo, and I felt it wasn't in-keeping with the GT car ethos
* Homelink programmable garage door opener - not needed, as the car lives outside
* Climate control panel in leather - the rest of the panel is plastic, it would stand out oddly if done in leather


So that's the starting point, and the car stayed like that for around 6 months before the modifications started. In order, I think they went like this over a period of 12 months or so:

* replacement final silencer from Ninemeister
* a single mass lightweight flywheel, also from Ninemeister
* Porsche 911 Cup car top mounts, Porsche shims and Porsche Motorsport rear toe arms to get a geo with increased camber all round
* a second set of wheels with PS4S tyres (my winter set)
* exterior decorative stripes in black vinyl and Porsche logo on the rear wing
* 3D printed seat inserts from Porsche Tequipment
* Manthey braided brake hoses
* race-spec brake fluid

At this point I was pretty happy with the car and having started doing track days I'd added some things to help the car on track. After wearing out the stock discs and pads I switched over to PFC discs with their 331/332 series pads which I've found to be excellent. They lasted for a few years and after a new set of front pads last year I've recently had a full set of new discs and pads fitted - the same again. If they ain't broke....

So after the initial small mods, the really big event was exactly 2 years ago when I worked with my OPC to get a set of Manthey 718 GT4 coilovers on the car. At this point they weren't yet Tequipment approved so it was all a bit off the books, but we managed to get a set sent to the UK and my OPC's Manthey technician fitted them and set them up. I started a thread about them here for anyone who's interested:


So that brings us to today. Where are we at?

Well, Wolfie and I have just ticked over 26,500 miles and around 25 track days together, including a PEC Precision Course at Silverstone. My driving is better than it was, but coming to the track day game later in life I just don't have the confidence to really lean on the car as I would have done as a younger man. So I have, and accept, my limits and I'm more than happy running around a track at mid-pace and having a bunch of laughs during the day with friends. You just can't beat it!

As for the car, well he's just returned from having the OEM silencer put back on as after 5.5 years I'd started to get annoyed with the drone between 2-3k revs. Most, if not all, aftermarket silencers for the 718 4.0ltr cars do it to a lesser or greater extent, so it's certainly not unique to the 9m option. Driving back from my OPC after the swap was an absolute pleasure and the car still sounds superb - I think those GPFs have had a good battering bouncing off 8,000rpm plenty of times...

As the Manthey coilovers are now Porsche Tequipment approved they are covered under the Extended Warranty scheme which I renewed at the 6 year service in March this year. Good job I did, as Wolfie also had a PADM replacement yesterday so the warranty has just paid for itself. Again. Which was nice.

So aside from the LWFW and the PFC discs and pads, everything on the car is now either factory Porsche, Porsche Tequipment (seat inserts and spare wheels), Porsche Motorsport (rear toe arms) or Manthey (coilovers and braided hoses). The flywheel is mega and really helps the engine spin up freely - I've found it really gives the car some character via enhanced feel between your right foot and the engine. Porsche discs and pads are OK but being drilled they crack really easily, and the pads are very soft which isn't good when they get to high temperatures on a summer track day. PFC have supplied 911 Cup and Supercup cars with brakes and a set of their discs and pads is around the same price as the OEM Porsche parts but much better suited to track work - the discs are grooved not drilled and the pads deal with high temperatures very well.

Cosmetically Wolfie still sports his stripes and Porsche logo, which are wearing pretty well to be honest, plus a bunch of circuit maps under the rear wing - one for every different circuit and/or layout we've done on a track day. He has a reasonable collection of small stone chips (I don't believe in PPF...) and plenty of scuffed plastics on his underside, but cars are meant to be driven. I'm fully embracing the Japanese concept of Wabi-Sabi here, which has a tendency to bring looks of bewilderment to some of the Cars and Coffee crowd!

The future. What does it look like?

It looks like more of the same to be honest! With the huge increase in the price of new cars I just can't just stomach the price to change to anything else. The only cars that would interest me would be manual GT3s, so £100k to change is just way out of my league. As long as I can continue to find work (I'm a self-employed contractor) then I'll just keep doing what I'm doing with my decidedly average driving skills and my brightly coloured two seater sports car -spectating at race meetings or driving around having fun on a PCGB trackday.

Thanks for reading, and if you got this far - well done!

I love these kind of open and clean reports, full of facts, full of owner's opinions (who better to judge things?) and looking to the past and the future.
"Excellent" from me, thanks for posting.
 
You're very welcome! I'm glad at least one person found my ramblings and read them 🤣

I can't imagine there are many (any?) people who've owned a 718 GT4 from new longer than I have, or messed about with them as much, so I thought it might be useful to share some experience.

The bottom line in my personal view? Don't bother changing exhausts, get a good geo done and do upgrade the brakes if you track regularly. Otherwise just drive it and enjoy it - these cars love regular use (y)

Best conclusion I've read for years on these cars.
 
Superb write-up, thoroughly enjoyed the read. Continue your obvious enjoyment of the GT4, I've always liked them
 
Thank you!

I find the 718 GT4 is a great car for UK roads and most tracks - it has just the right amount of torquey power and handling prowess to be fun whatever you're doing. With current values way under £100k they're also easy to insure and maintenance costs can be fairly reasonable. I think they're in a real sweet spot of the Porsche family.

But I would say that being ever so slightly biased ;)

Unfortunately the Manthey coilovers have become hideously overpriced which is a real shame. They really do suit the car and give even average pedallers like me a lot of confidence on both road and track, and also the wet and dry. I've been hugely impressed by them.
 
Well done for proving such an interesting and informative read Dave, and good to hear that you’re still enjoying ownership - on road and track - after 6-years [is it really that long?😳]. Your comment about just enjoying the car on-track at your own pace is spot on.👍

I fear that your comment about droning aftermarket exhausts will chime with many owners who have taken that route. Many years spent working with different manufacturers on sound, vibration and refinement issues showed me how much effort is put into the development of intake and exhaust systems to minimise annoying powertrain booms throughout the rev range while still maintaining an interesting sound quality.

Continue enjoying your GT4, using it for the purpose for which it was designed.

Cheers Jeff!

The "my own pace" thing on track days is definitely my comfort zone. I'm old enough now to be at my happiest well inside the limits of both me and the car - a decent safety margin is a must, and it's a darn sight cheaper on consumables too! 🤣

As always, with your experience you're spot on about the NVH - after driving around a lot today I've been reminded just how good the Porsche OEM exhaust system is on the 718 4.0ltr cars. They must have spent a LOT of time and effort getting it right - I think it may be the reason the car took quite a long time to come to market...
 
Thank you for the great write up Dave. You have one of the best foundations for the future and I think many are concluding that rebuilds and refreshes are way cheaper than the cost of change, with the benefit that you get everything you want. Chatting to a dealer yesterday confirmed the view that Caymans are now holding their values, with the newer ones starting to rise. Dealers are unable to buy cheap anymore, so the only way to make money is to push up the values.

John
 
Cheers John. Caymans across the board do seem to have bottomed out a little while ago and have now risen a little. I was fortunate to both get the car from new, and then get the Manthey coilovers before the ridiculous price hike. I can't find them on the Porsche site any more, but here they are on the RPM Technick site (current price is £15,889.96 plus fitting!!!!!!)


A manual 718 GT4 with this passive suspension and no modern driver warning systems etc was about as old-skool as you can get in an almost new car, along with the 991.2 and 992.1 GT3s. For those of us of a certain age, who enjoy the Cayman platform, it's about as good as it gets (along with the GTS 4.0) and they are unfortunately never to be repeated.

Enjoy them while you still can, folks!
 
I'm somewhere down the same path. I got mine (also an early one) already with 17k miles February 2025 and it is upto about 22k now with 6 track days done. It was quite heavily specced from factory including the clubsport pack, it does have the PCCBs which do make me nervous but in the worst case I would probably do a conversion either to aftermarket steel discs or try the surface transforms.

Interesting on the exhaust, I'm probably not going to change mine though I'm sometimes tempted but I don't want to worry about getting thrown off a trackday.

I got the motorsport toe arms and some camber shims from Parr in the winter along with the Manthey brake hoses and pads.

I do have the Porsche warranty though and will keep it another year, the absolute cost of warranty is definitely worth it but the additional cost of OPC servicing over a good specialist is what makes it more marginal (and the Pagid RSC pads are half the price of the Manthey ones which I think are also made by Pagid). There also seem to be aftermarket PADM fixes/upgrades that look like they more robust - knowing of that issue is definitely one to think about for warranty.

I think if I do keep going I'm probably more likely to go with non-Manthey suspension given the price these days, I think at the older prices I would make a different choice. I don't know how much of the cost I could man-maths into resale value though so I'm going to stay stock for a while.

I also am starting to think about tyre options as my second set of Cup 2s only have about a trackday left. I'll probably stick with them, I've found them pretty good, even in the wet which I was very nervous of.
 
Great stuff - definitely sounds like a similar path to mine!

I really wouldn't bother with an exhaust - definitely not worth it based on my experience. There's no need to worry about noise levels at track days if you just change the silencer as the OEM box is unsilenced when the valves are open - the main silencing at that point is coming from the over-axle pipes and their OPF filters. My car registered the same volume with both systems, give or take the operator variation of 1-2dB.

A LWFW is definitely worth considering though, and would make most sense to swap it in when you need a new clutch.

I run the extended warranty on my car as my local specialist is now almost as expensive as my OPC, plus I have an excellent relationship with the OPC Service Department. If you have a good, local and cheap Indy then it's definitely a tougher call to make. The PADM fixes are still fairly expensive, but I guess they may only need to be done once. I've had several other things done under extended warranty (indicator repeater, engine seals, gear shift cables etc) so I'm happy to keep it running. I've also been told that if I ever let it lapse I would need to have the coilovers serviced before the warranty can be re-added. They have to go back to Germany and cost ££££££££....

Cup2s are the Gold Standard if you do track days and road miles, just avoid standing water if at all possible. PS4Ss are brilliant on the road but get too hot on track unless the air temp is in single figures, plus they are also available in N-rated versions. Other brands are of course available but hardly anyone I know uses them.
