My guess was a generic 3000 since it had to be about the same-ish as my 987.1. I have dieted losing 5# for the Soul exhaust, and guessing that I lost 5# a corner with the new 2pc brake discs.

Our Porsche Cayman is all fixed, but what does a bone-stock, base model 981-chassis Porsche Cayman weigh? It’s time to find out, so we rolled the car across our Intercomp SW777RFX Wireless Professional Scale System.
[What’s it weigh? LFX V6-swapped Miata edition.]
We weighed the car with 3/4 of a tank of fuel and no driver. And the result? As it turns out, this car is lighter than we expected—just 2973 lbs.
No, it’s no Miata, but compared to other modern two-door coupes for the track, it’s about 100 pounds heavier than a Toyota GR86 (2811 pounds base manual, 2851 pounds base automatic), and about 200-400 pounds lighter than a Supra (3389 pounds manual, 3411 pounds automatic).
We’re just thrilled to be playing with a modern car where the weight’s first digit is a “2.”

Considering the pounds the newer cars pack, this is a pleasant surprise. It also seems relatively well balanced, although throw a driver into it and it might have a slight left-side bias.
This makes me wonder what the lightest new car available is.
I imagine it will be something like a Miata, Toyoburu or even Mitsubishi Mirage.
More research is needed...
I think it's pretty much guaranteed to have a left-side bias with a driver unless you also install a passenger. However, that's the case for any car that's not ballasted to offset the driver's weight or has a central seating position :)
It's a little chunky IMO. That's 500 lbs heavier than an ND Miata with a 500 hp V8 in it. 400 if you want that Miata to be an RF - and the Miata is newer.

Interesting perception of weight. The Toyoburu is roughly 500 lbs heavier than an ND Miata - the latter flirts with the 2300 lb barrier in the right trim. Good call on the Mirage, though - Wikipedia says it's under 2000. I can't find a spec sheet on the Mitsubishi site to confirm.
In reply to Keith Tanner :
Just to ballpark, what is the cost of said ND Miata with the V8 swap all in? Would it be cheaper than a decently optioned 981 cayman, or more expensive?
In reply to cmcmillin31 :
It will be more expensive than a used 10-year-old Porsche, especially if you buy your Cayman with a busted trans. It is also faster :) They're not really available on the used market (only two have ever changed hands) and I think the current cost of the conversion is about $50k plus Miata.
But the question wasn't how much the Porsche cost per pound, it was how heavy it was. The Miata isn't lighter because it's full of high dollar fancy parts, it's lighter because Mazda made the ND more than 600 lbs lighter than Porsche made the Cayman - and at a retail price in the low $20s when new. That just gives us the margin to yank out the four cylinder and install a beefier drivetrain without approaching the weight of the Porsche. The Miata is more expensive because it's effectively a hand-built car and a whole drivetrain gets discarded in the process.
I don't think it's quite fair to compare the Cayman to an ND, though, even an RF. They're not even on the same planet NVH-wise, nor should they be given the intended markets/price points. Heck, the Cayman has a big steel weight on the shift linkage just to make fore-aft shifts feel sturdier, and the battery is about the size of the ND's engine block.

I had a hard time tracking down a spec sheet, too, but I at least found a spec sheet for the 2021 Mirage:
From left to right, Mirage ES, Mirage LE, Mirage Carbonite Edition, Mirage SE

True about the bias, but I like thinking about the driver. Installing a passenger - at least the ones I find - increases NVH. Need quieter ballast
