718 Spyder RS been spotted testing.
That'll be good news for those that like 4RS but think they'd have no chance of ordering a car, I'd say some that have a promised slot will transfer to the Spyder RS, thus making more 4RS's available.

So a win-win for some smile

Me, sticking with the 4RS.

My albeit limited experience with this engine is that manual is nice for pottering around, have some fun or on the road, but as soon as you want to REALLY unleash the performance, with serious intent.. PDK allows you to do that more effectively.
Not because of the power, but because if the sharpness, response and sound… it’s optimised with PDK.

But good that there are choices, across the various models it has become available in.

Yep - as always T, it comes down to how you use the car. I think most people would agree that PDK is generally the best choice for maximum performance and regular track use where lap times are important.

For me, with only one car and mostly road use with occasional track days where I'm not bothered about times, a manual is a must-have for my personal maximum enjoyment and interaction. I also like the challenge of one on track - it's more old skool.

I totally agree it's great to have the choice, although a manual RS would be fantastic. If only!

I don’t think anyone has ever driven the car and said the same… reminds me of someone on here who thought there was a “handling issue” because they clattered a kerb at the ring, at a point where you get air. Err yep, you will experience fishtailing if you smack a kerb at the same time the road falls away from you

Oh that was me cheeky. To be fair It was in a Spyder and not a GT4 but still geo optimized with rear arms changed. However that was not the only occasion that that particular car gave me a big scare on track. I am also far from a driving god like yourself clearly.

My beef with the chassis of that car was that it was quite unforgiving at the rear at or over the limit of grip. I certainly would not describe it as “loose” just a bit of a handful sometimes. An issue that I never had with my 981 GT4 on track which I thought was superb.
I can throw my R8 track car around with far more confidence than I ever could with that Spyder. Including kerb hopping!
Just my experience of one particular car.

Still hopeful than a 4RS might eventually come my way so that I can experiment some more with the Cayster platform. I am “on the list” should Porsche actually build any rolleyes
Not just you Bigmoley. The kinematics of all Caymans are heavily compromised by being a strut. They have lots of undesirable on limit geometry under load....especially when there's a load change due to a bump. You can go some way to fixing it by stopping the rear suspension from moving. In other words, if you ramp the compression damping up a lot and then stick a tonne of static camber on the rear end then you push the point at which it does weird things higher and higher. This is exactly how the Cayman GT4 race cars are set up, and is also why going stiffer on the rear bar (which would normally make oversteer worse) helps things a little bit.

I took my 981 to Croft yesterday to do the Javelin Sprint (amusingly I got removed from the results for an as yet to be clarified reason....but it would appear to be because I had to go home before the prize giving and someone complained I turned up in a Porsche or something) and you can see the issues in the higher speed corners. I'd probably describe the lap as 'stressful' laugh



It amused me a little when a few micro analysed the official 4RS lap record at the Ring and seemed to think that a 'better' driver would find a few seconds extra without really understanding the way in which the Cayman is compromised....but then that's what the YouTube comments section on driving videos is for right? Keyboard co drivers who could do it better!
Just my feedback after a track day at thruxton on my geo’ed pdk spyder. I run -2/-1.8 with slight toe in at the rear. Personally; I agree with romo, big mowley and Racermike. The car just doesn’t give you the confidence to plant it at high speed corners. I keep feeling that the rear end s goin to step out at 4th gear cornering speeds. Having driven at the same circuit in my e46 track car and the A110s the circuit has on loan, I’m a bit disappointed. Perhaps it’s a case of me getting use to a looser rear end and finding the courage.

Luckily my spyder is a hairdresser car and I dun feel as bad 😀

Yup I would imagine that Church taken as fast as possible could be very, very interesting. Probably ok for a few laps and then a god almighty rear end step out just to focus the mind laugh

no chance man.

you need a big lift before going in......otherwise. I had a bit of a wobble at church after building up courage over a few sessions. Think I rather not have an expensive lesson.....

Wish I was a better wheel man. Where's Racermike?

Maybe we should all be looking at the A110. Not great on straights but think of the consumables.......

Isn't the R8 too heavy though, much like the M4 CSL (Could Still b Lighter). There is nothing straight out of the box without a ruinous price

Can't say I think much of the GT4RS styling, it looks like a teenager designed it and wanted one of everything available in the Demon Tweaks catalogue. I feel like black might be the best colour so all the fussy details blend in more. The GT4 is a much better looking car to my eyes.

I agree it'll look so much better in Black especially with full Weissach pack and Black Mags. Don't really like it in any other colour. Anyway its all moot at the end of the day with very limited numbers.

ETA Much prefer the upcoming Spyder RS even though I'm not going to lower myself to beg my OPC for one.

Most likely !. However for every 'flipper' there has to be willing partner in crime. It takes two to tango.

That substantiates my hypothesis that the noise is a '5 minute wonder' and will get irritating in no time.

100% this. It is a total abomination in its looks.

Well I think it looks bloody great smile
As for the noise, yes please, it’s a track day toy not a limo, just got to get the exhaust to match the intake and it will be brilliant. The current GT4 and Spyder are just not at the races when it comes to how they sound.
In my mind the jury is firmly out on just how good a track car but the post a couple of posts up sounds very hopeful from someone who has drive both 4RS and GT3.
Fingers firmly crossed that one day I get chance to find out for myself driving

The noise comment was interesting. Race drivers and testers (often ex racers) are not exactly afraid of a bit of noise, so to have a comment made about ear plugs was interesting

But for avoidance of doubt, if I got the chance I’d have one all day long - and the orange looks fine to me, have seen worse colour combos

Weirdly, full LED headlights don't require headlamp washers under the European Homologation regs, but HiDs/Xenon's do. I would assume potentially due to better control of the light beam, but it confused me too, since there are a number of cars recently I've noticed with full LED headlights that don't have washers and had to ask someone at work.
