why not double wishbones?
I've always wondered why Porsche insist on sticking with struts, although to be fair they seem to make them work far better than they have any right to. I guess an upper wishbone at the front would eat into the luggage space but I don't know why they don't have one at the rear - maybe sometime to do with the width of the engine? The Pits said:
It should stop well with GT3 brakes though. But is it actually any lighter than a GT3?
They appear to be close enough that it'll depends on which options are specified. I'm guessing the difference between a car with air-con and the 18-way electric seats and a car with no air-con and the carbon buckets is going to be well over 100kg. I've no idea whether Porsche quote the weight of the standard car or with the lightest set of options?

Those carbon buckets are amazing. I bet they make your wallet considerably lighter too!
Clearly there's a Porsche buying frenzy going on out there but actually the Cayman has been a very slow seller for Porsche. They only sold 85 GTS last year. By Porsche standards that's a dismal failure.
I can't help but think the buyers are looking at the GT4 as a cheaper way of getting into a 'GT' car rather than a high-spec Cayman. Though for those few who don't like the rear engine layout, the mid-engined Cayman does have its own appeal.
At the same weight as a GT3 (or potentially even heavier), isn't there the danger of it feeling like a slower, budget spec GT3? Having driven a 991 GT3, it's fast but it's nothing like as ballistic as the journalists like to make out. It's merely fast as a 1400kg 468bhp car should be but no more. Any talk of it being 500bhp is complete rubbish. Just look what they had to do with the GT3RS to achieve 500ps. There are no youtube videos of stock GT3s making 500bhp on the dyno.
Maybe not on the road but on the track a 380bhp version of the GT3 would definitely be underwhelming.

Only 60-70kg I reckon. Traditionally Porsche have quoted the mass of the lightest spec car so I wouldn't expect it to change.

Note with the seats - those carbon buckets still have thorax airbags (otherwise they wouldn't be able to sell them in some markets) and now have electrical height adjustment (unlike previously offered buckets), so don't expect the weight saving of a single piece carbon racing shell. Numbers for the air con are elusive, but the last time I heard that was only in the 20kg range and thus you'd have to be mad to delete it for that.
That surprises me. The Elise's rather pathetic air-con system weighs about twice that.
With respect to seats, the only real point of reference I have is the M3 CSL, where something daft like 80kg of the saving came from the change of seats and the standard E46 seats don't have anything like 18 way adjustment. Maybe, as you imply, these carbon bucket seats are pretty heavy.
If they're quoting the lightest version, that means the GT4 is, like for like, quite a lot heavier than the standard 'S'.

Hmm, I've seen two nominally identical cars other than the fact that one had air-con and one didn't, with the same amount of fuel in them (both full), on the same weighbridge and the difference was over 30kg. Mine (without) was 810kg, the other was something like 845; both MY04 S2 111Ss with the soft-top on. Edited by kambites on Monday 9th March 15:14
