Doesn't seem to be gone yet, but that is almost exactly as I'd have spec'd one. Lovely! Annoyingly, I'm probably 2-3 years away from looking for a Porsche as a "hobby car", because that would very likely be the one. In between times I'll make do with what I have, and hope there are still a couple about when the time comes.Liam

I know this was discussed recently: differences between the R and the standard S.
Just posted this summary in my build thread - I've excluded cosmetics, but other than that, let me know if I've missed anything.

I took some time to research the weight, chassis and power changes for the Cayman R.
Compared to a standard 987.2 Boxster/Cayman S, what's different, and what would it cost to match the R?
1. Weight
Air conditioning & speaker delete (15 kg): The majority of Cayman R's were specced with air conditioning and speakers, so we'll skip this weight saving.
Aluminium doors & panels (15 kg): Aluminium doors & panels would be totally cost ineffective, but you can save the same 15kg using a lithium battery (see MotoIQ). This would also lower the car's centre of mass. A 60Ah Antigravity battery costs around £1000.
Bucket seats (12 kg): A pair of Recaro Pole Position or Corbeau GT3 seats will give you the same weight saving as those beautiful carbon-buckets in the Cayman R. I've always loved the look of 'elephant ear' 996 GT3 seats, so would go with Corbeau seats. Let's call it £3000 for the carbon-fibre, leather variants with mounts, minus selling the standard 987/997 sport seats for £1500.
Other (8 kg): Porsche didn't detail what's in the other category, but it's probably small details all over the car like the spoiler motor delete, fabric door handles, etc. If you wanted to save 8kg, you could start by removing the rear spoiler motor (-3kg) and NVH foam above the engine (-5kg). There are probably lots of other areas I haven't thought of. Cost: £0.
Lightweight BBS rims (5 kg): It's a little known fact that the Carrera S II alloys are also lightweight rims made by BBS, and weigh near-enough the same as a set of Cayman R rims (see 944Racing). Cost: £0, since my car already has them.
Weight saving: 40kg
Total cost: £2500
2. Chassis
Limited-slip differential: The Cayman R LSD has tiny friction plates and zero preload, meaning it's as close as it gets to being an open differential, while still having LSD listed on the spec sheet. Given how quickly Porsche's street LSDs are known to wear out (as little as 2-3 track days in a 996 GT3, which has 50% larger friction plates), I'm going to make the bold assumption that most Cayman Rs have open differentials by now. So, we'll skip the LSD - but I would like to fit a proper plated LSD in the future, such as an OS Giken. Interesting reading: Cayman R LSD - Planet-9, PH | 996 GT3 LSD - Rennlist, PH. Cost: £0.
Springs & dampers (-20 mm): Brand new Cayman R springs and dampers are available from Porsche for £2200 inc. VAT. Seems like a bargain compared to Ohlins R&T coilovers which get mixed feedback, cost 50% more, and are designed to be serviced after 18,000 miles or 5 track days. Good condition, used springs & dampers sell for around £400.
Rear anti-roll bar: The Cayman R has a thicker rear anti-roll bar. A brand new one including mounts costs £250 inc. VAT from Porsche.
Total cost: £2050
3. Power
Using the 987 Boxster & Cayman part catalogues, I asked AI to compare the part numbers for the intake, engine and exhaust between each model: the Boxster S (310 hp), Boxster Spyder (320 hp), Cayman S (320 hp) and Cayman R (330 hp).
Turns out every model shares identical part numbers, with the exception of the Cayman R, which has different exhaust silencers.
Exhaust silencers (10 hp): The Cayman R silencers have a 55mm inlet instead of the standard 48mm. While many don't think this adds any power, let's assume it's how Porsche managed to get an extra 10hp out of the R, compared to the Boxster Spyder and Cayman S. Instead of the silencers, you could replace an even more restrictive section of the exhaust: the catalytic converters. Carnewal 200-cell cats cost about £1500 delivered.
Engine map (10 hp): Add £500 for 4 hours of rolling-road mapping at Chipwizards - to remove the artificial 10hp limitation for the Boxster S and fine-tune - and I suspect you'll have more power than a Cayman R.
Extra power: 20hp
Total cost: £2000
Summary
That's it. For around £6500 inc. VAT in parts & tuning, you d have a 987.2 that's as lightweight as the Cayman R, with carbon-fibre bucket seats, brand new springs & dampers, and similar power. Depending how much work you're doing yourself, you'll need to add labour costs.
Of course, not all of these are worth spending the money on. Which parts would you choose?

My old car…… it may have a few miles but that car is a peach!! I had it for 10 years and it never missed a beat, never saw a salted road (it did see wet roads contrary to the video posted on it), was the car featured on JayEmm on Cars YouTube channel, and it lived a pampered life with me! https://www.autotrader.co.uk/car-details/202602260...

If anyone here bought it, or know who did, I’d love to know where it went and where it goes next. Loved that car, and only the draw of a 991.1 GT3 finally tempted me out of it.
