After just over a year of ownership from new my 718 GT4 is clocking 8000 miles (they flew by!) which tells me everything I need to know about this one being a long termer.

I used to dabble in UK club racing so the GT4 was meant to be a stepping stone track day car into one day, a 992.2 GT3. After 8000 miles, road trips and a fair bit of track days bullying much faster machinery the GT4 platform is just too good. Will I be able to make the switch to a GT3? I am really not sure. Paying overs certainly does not make any sense as the GT3 is definitively not double the car of a GT4, especially when pushed.

With surface transform brakes and the Manthey Racing conversion coming up it will finally be the car it was always meant to be, not hamstrung by Porsche to keep the GT3 well protected.

Didn't think I would end up feeling this way about the car so who knows what's next... JCR exhaust to free up some HP, Michelin Cup 2R's with the MR upgrades?

Respect to all the owners out there who use their cars and throw mileage on them. I feel sorry for those cars on sale with 2000 miles and 27 owners

Good to hear another person enjoying what I feel is a great platform. I'm 3yrs and 13k miles in with mine.

I wouldn't bother with the exhaust unless you're feeling flush, but if you have a manual I'd get a lightweight flywheel as it transforms the car IMHO. Other than chassis mods and brake upgrades they don't need anything else to have fun with them. They'll never be as fast as a GT3 if you're after outright speed, but fun isn't always defined that way.

Enjoy the MR kit and STs, that's the way TDT on here has gone. I'm not that deep pocketed so I've gone the poor man's route - Porsche Motorsport chassis parts, MR braided lines and a set of PFC discs and pads in the garage for when the OEM parts wear out driving

Yep recently posted on the other GT4 thread they are effectively 85% of a GT3 at half the money.

Talking of owners there is currently a 2020 GT4 with 7 owners for sale at an OPC. hehe

Great package for sure especially at the money.

Thanks Twinfan! 13k miles is great going!

With the chassis upgrades I am hoping it should at least match a stock 991 GT3 depending on track. In a GT4 it's really about throwing the car into the corners and carrying as much speed as possible vs managing weight transfer in a GT3 and hammering the loud pedal on exit. Regardless there is no chance of keeping up with 992 GT3 in the right hands.

Seeing the JCR GT4 the other day at Donington was nuts. With an extra 45hp and MR dampers, it was an epic demo of what the chassis can do, pretty much overtaking everything.

I hear you on the brake hardware, I cooked my OEM pads after only 3 track days using PCCBs. Those discs never saw a track day again biggrin !

Yea and each of those 'drivers' will tell you they made money on each flip... or it was a gateway to a GT3 which they either can't or won't drive

Yeah, you should be in the 991 GT3 ballpark apart from the straights where they'll pull away. Nothing you can do about that with an 85bhp defecit unfortunately!

I'm on steels, and being an average driver still new to track days the OEM parts have held up pretty well so far. I'm trying to avoid changing them before their time as they're not cheap but the lack of bite is annoying me a bit. I'll see how I get on this month then decide if I'll change them for the summer season biggrin

I started with a CR in 2011 and caught the bug.

Now done over 60,000 miles in this and the GT4 that I changed the CR for and I completely agree with you.

It can go wrong, but you have to be going pretty quickly ... and I've so far got away with it.

Better than for trackdays, it is also a fantastic car on the road where the extra grunt of a GT3 is absolutely useless.

Long term GT4 and GT3 owner here.
GT4 as good as or better than a GT3 on road and track, really!!!!! I will have some of what you lads are smoking please.
The GT4 is OK on track especially for an out of the box road car, but the fundamental limitations of the suspension, especially the rear, is all too apparent once you are really on it. I personally find that controllability at and over the limit of rear grip is not that great. By comparison I have two other mid engined track cars both with more sophisticated rear suspension set ups which are far nicer to drive fast. The GT3 by comparison is also more benign at the limit and with the added bonus of the superb traction. It’s a very different car to drive but more sophisticated.

Throw in the very average engine in the GT4 with the lousy gear ratios and the rowdy cabin and it’s a GT3 all the way for me.

Once you start modifying the GT4 then it’s not an apples for apples comparison. I think the stock GT3 provides a good point of reference for a GT4 owner aspiring to go quicker. Something to chase if you will.

I think from the non-racing driver perspective it's a very capable car which with a few choice modifications at modest cost can be a much more rounded usable car than the GT3 ... for both track and road use, at a comparatively affordable cost.

Accepted that the rear suspension is a compromise, ... as retained by the GT4RS !!

Of course it isn't a GT3 ... the new GT3RS doesn't even have a boot.

I have to agree that, although a good car, let’s not get ahead of ourselves

GT3 is the fastest and has the most tech. It’s not compromised

GT4RS is closest to a GT4 without compromise

GT4 gearing is awful, and is the only Porsche cayman you’d say is geared for track with the aero. Not to say a cayman S isn’t fun on track, but it is a 90% road car

Personally, if the GT4 had the RS gearing, that would have been perfect for me. Around 100k, enough grunt, fun to drive, happy days.

Oh my spec it’s 110k for GT4 (then add MR bits), and 160k for the RS (plus more expensive MR bits). These aren’t small numbers

I’m looking forward to the RS but it’s a lot of cash in a car you’re going to be putting on track regularly, which is often what some GT3 owners cite when at places like the ring


I’d say the perfect track car that’s actually available is a 981 GT4 with the gearbox mod to shorten ratios. Just a shame it didn’t have PDK as I’d prefer that

About 80k of car and fast enough for most people. Could be sub 7.30 at the ring, really engaging, and not the value of houses in some parts of the country!

GT3s aren’t really cars I care for. They’re always going to be surpassed by a later gen and although epic, most owners seem to do sod all miles on them before flipping on. On track they’re harder to drive on the limit (as with any car that has more grip - it has more and more, until it doesn’t. If you’ve driven on slicks, its a similar experience IMO), and although faster than the 4RS, it’s not so noticeable

If you’re in a GT4 and chase a GT3, it’s no contest. Anyone who wants to pipe up with, “I’ve overtaken GT3s” - great, as have I, but that’s a driver issue not a car one. With a similar driver, they’d simply pull away - both in a straight line and in corners. A 4RS v GT3 is far closer

For me I’ve been very slowly getting used to mine…. After jumping out of my tweaked 981 GT4… the 718 has taken some time and miles to ingratiate itself to me…. We are getting there…. 1200 mile round trip to the N’ring, laps and then drive back through sun, wind and flood have brought us closer.

Key to this for me was getting the chassis back into the proper operating window… it has taken a couple shots at ride height adjustment but it’s right there now, responsive, compliant and grippy.

The long distance was easily eaten up by the car. Same journey last year in the 981 was a bit more taxing due to the little bit of drone zone from valveless exhaust - 718 was nice and quiet when I wanted it to be and gave some noise when I wanted that also… albeit not as nice as the 981. The low and midrange torque was nice to just surf on the road also. Sneaky speed.

On the N’ring the car performed brilliant and I was thinking… on balance (performance Vs cost) why would you ever need more?
If you want to see a Sunday drive…. biggrin



But then, I took a pax lap in a PDK 992 GT3 Touring.
Put simply… you do need more. Lol.
992 GT3 just can do things no Cayman, 4RS and MR kits included, just can never do.
The engine and gearbox are perfectly mated and of course 4RS has that… but on the chassis side the 992 has higher limits, more grip and more range of control… especially over kerbs and bumps were the arm geometry both front and rear manages wheel and body motion so well. It was an eye opener. This is the real difference between a Cayman and a 911. 911 chassis is more sophisticated. End of. That equates to speed….
That said the more basic nature of the Cayman is more fun or immediate and offers up the thrills much sooner and more easily.

I hear what you're saying T, but a more sophisticated chassis and more speed is only really relevant on track - and only then if you're looking to achieve maximum lap times.

For me, where track laps are only around 15-20% of my annual mileage and having a solid day of fun with like-minded people is more important than outright pace, a 718 GT4 is MUCH more appealing than a GT3. And that's before we get to the thorny issue of respective purchase prices, running costs and insurance.

We all have different priorities, and I wouldn't pay the huge amount it would cost to swap my GT4 for some sort of GT 911......

I think that the chassis point translates to fast road as well.
The 2 platforms are at different price points and offer different experiences, so it’s just down to:

A - What you prefer.
B - Willing to pay.

For some people.. it’s 1A and 2B like that…. Other is 1B and 2A.

Last year I was DEFINITELY not willing to pay a massive delta to get into a 991 GT3 Vs my tweaked 981…. Because I didn’t think 991 GT3 was worth double my car and also because those cars were already 3/4 years old.
991 GT3 came onto the radar because of 4RS pricing…
So in the interim I elected to take sidestep into a 718 GT4, and continue the journey, until things shake out a bit further down the line.
I am enjoying the journey…for me I’m not yet sure this specific car is a keeper, as I do have my eye on 4RS,(unless I can keep both) but the platform definitely is.
As you say there is a cool group of us that have these cars and it great fun to talk and meet up etc etc.

As for the future, nobody said you can’t have a GT4(RS) and a 911 lol.

No, I guess not! Some of us can't have fleets of cars though, much as we'd like to! biggrin

It's great that there's the choice out there. Now if only Porsche would put out a Cayman with the GT3 engine and a manual gearbox... driving

I agree with all this.

If I could buy a GT4RS I would ... but for the moment my modified 981 GT4 is perfect ... and it now does everything that I ever wanted it to do ...

On the other hand, it has cost me the same as my spec of GT4RS but with almost eight years of fun in my pocket ...

It is a tremendous platform, so convenient and fast enough (for me) ...

The chassis differences definitely translates to road. And you don’t even need the double wishbone front of the 992 GT3 to feel it. Having swapped between various 911’s and GT4’s it doesn’t take much to feel the difference, particularly on a bumpy and tricky road. The faithfulness of the rear end in a modern 911 is very easy to feel when the pace picks up. And that’s before you get to the additional traction you can lean on in the 911 as well.

The GT4 is a brilliant thing. And I absolutely love them. But it’s limitations will always be that rear and.

The chat about the chassis… not convinced, but I guess it depends on how you define chassis

The GT3 is quicker than the 4RS primarily because of additional aero and more rubber. I was surprised the 4RS had the same size tyres to be honest

The double wishbone at the front - yes, better, but has only come into the latest model so let’s not pretend the 991.2 - which is a phenomenal car - is a poor choice of car because it doesn’t have the front double wishbone

It also comes down to what you have experienced. Have you been out in a sub7 drive round the ring in a GT3 and then an equivalent in a 4RS?

And then seen the 3MR and 4RS MR?

Then have you experienced the 3RS at near max potential?

Answer will be no to some of the above, so it’s difficult to see how anyone can really comment on how the cars handle kerbs based on how they’re meant to be driven … and by that I mean, the stiffer the suspension (RS), the faster you need to be to experience it working as intended

An RS car driven at 50% feels like utter garbage. Way too stiff, bouncy, downright dangerous. For me, I don’t think I could drive an RS hard enough to get the suspension working as it should

Indeed, most track day drivers can’t drive the cars fast enough to get the RS suspension and aero working. The MR kits make it easier to drive, inspiring confidence, and therefore end up being relatively faster in the hands of an amateur than the difference for pro drivers … hence why the MR kits bring the cars alive for us amateurs


Point being… don’t just buy the best car. Buy the best car for you

If you’re lapping at 7.30, use a GT4. It has potential to go 28s quicker (based on MR hot lap), and many amateurs have sub 7.20 laps

If you’re at 7.15 and wanting “more”, then look at the RS or a GT3

But if you’re doing 7.45 laps in a GT3/4/RS, the better the car, the worst it would feel to drive

Thread resurrection ...

Having just sold my MR-esque 981GT4 for a non-Weissach 991.2 GT3RS ... I have my first trackday in it at Oulton later this month and following that I have the car booked in for a Geo check / set-up, though Porsche recommend the same settings for both road and circuit driving. Hence most of my driving over the last couple of months ahas been on the road.

Coincidentally on the way to Track Torque there is the most lovely North Yorkshire road ... re-surfaced and smoother bumpy in part and non re-surfaced bumpy bumpy in part. On the outward journey I ran at my usual pace and thought ... this is better than I expected ... and on the return journey I found myself following a hot-hatch driver with something to prove (maybe even checking out his/her suspension set-up ?!). At X + 20mph the GT3 really surprised me ... supple / controlled / grippy, it was just think the car in, point, settle and shoot in one almost instantaneous process.

It's the settling point that I always feel for that gives me the confidence to press on ... and it was very very good.

This was on Cup 2's with Weissach Mag wheels ... at the moment I plan to keep the steel brakes since ST wouldn't service my existing ST's and return them with GT3 bells ... The Weissach wheels IMHO save a brake discs equivalent of over 20KG's in unsprung mass effect which allows the suspension to work as well as possible.

This video might be old news for some but as there were lots of comments that the 991 chassis was an upgrade from the 918 GT4, this might be useful info for some others

The 991, 981 and 718 platform/chassis are essentially identical and it's only with the 992 generation that there has been a significant upgrade

What about the multilink rear suspension and RWS of the GT3 ?

And the extra adjustability of the GT3 ??

Or has this just been imagined back into the GT4 that I had to modify just to avoid wearing the shoulders off the front tyres, etc. The GT4RS is the same.
