The RPM Technik is 100% the one I'd buy if I had the money but it's more than double everything else I've seen. Absolutely gorgeous though.
I totally get you but I only trimmed two small spots to allow the hinge full freedom of moment. If you don’t plan on painting, their fitment is 100%, comes with mesh and weighs 4.3lbs. I believe 9XX makes the second best and then everyone else. Ruf made one but it’s twice the price of the RPM. By the time you paint and fit, it’ll be the price of the CSR.
Honestly I'm starting to lean in that direction unless I can find a good deal on a used one since you're 100% right about the cost of paint and fitment. Just gonna have to be a bit more patient.

Honestly I’d watch the $ to £ market and buy then. They discontinued their cf hoods so maybe there’s a chance they’ll do the same for their other bits. Been trying to get a confirmation on one of their CF CSR bumpers.
I highly doubt a ducktail or any factory-ish wing would significantly limit top.speed.
It might not. But then again, something cut 2 kmph or mph from the top speed of the 997 Sport Classic, and I haven't seen any reason to remove the ducktail from the rather short list of suspects.
On the other hand, if you look at the hp and top speeds of the 996.1 and 996.2 Carreras, you would expect that if you raised their hp to same-generation GT3 levels, their top speeds would rise to 298 and 302 kph. In fact, though, the 996.1 and 996.2 GT3's top speeds are even higher - 302 and 306, suggesting that their big bumpers, spoilers, and wings, plus the side skirts, actually reduce drag. Of course, there is more to the story. The GT3s might benefit from being lower. On the other hand, they are probably slowed down by venting radiator air into brake ducts, and who knows what the impact of wider tires is. And finally, the Carreras have quite a bit less than their full 300 and 320 hp available at VMax, given that VMax comes at a higher rpm than peak hp, after which torque drops rapidly. Whereas the higher-revving GT3s might be using a larger portion of their hp at VMax (or might not, if their 6th gear is too optimized for track and peak hp is below the redline). (One could probably figure out the impact this last bit makes, using each car's torque curve and gearing.)

I also talked to them about their bumpers recently. They said they are just reselling Porsche's aerokit bumper, and for people outside of the UK such as myself, they recommended buying locally. Maybe they used to have a CF bumper, don't know. On the other hand, their side skirts are CF. They make them b/c they can make and sell them for less than the Porsche aerokit items.
Any idea of how much all this weighs compared to what's removed?
The stock lid for my '99 C2 weighs 21.2 lbs. The lid with Carrera wing weighs several pounds less. I'll see if I can find the picture I took when I weighed it.
It might not. But then again, something cut 2 kmph or mph from the top speed of the 997 Sport Classic, and I haven't seen any reason to remove the ducktail from the rather short list of suspects.

never really looked into the 997 sport classic but if its similar to the 996 sport classic its a little heavier then a gt3. It could be also be weather conditions at testing.
It could be also be weather conditions at testing.
I guess that can't be ruled out. Strikes me as unlikely though. I'm pretty sure they test at Nardo, so wind shouldn't be a factor, as they travel in all directions around the circle. (And they are allowed to add a bit to the speed to compensate for the loss resulting from gently turning - apparently all manufacturers testing there do this.) I'd also suspect - TBC - that they do a lot more than one lap. And, possibly related to this, they surely want to quote as high speed as they can. So they probably either wait for favorable weather conditions, or keep testing until they get a result they like.
The top speeds of all the other 996 and 997s without Metzger engines seem to make sense considering the hp. (The one that might seem an exception is the 996 C4S, which is explained by it's wider hips (and not by it's Turbo-ish front end, which does not seem to add any drag to the 40AE), and having driven several C4Ss on the autobahn, somewhere above 200 kmph (124 mph) you can really feel that they accelerate less a Carrera. So if they got the 997 Sport Classic wrong, that would seem to be an unusual exception.)

Weight shouldn't actually affect top speed. For the 997 Sport Classic, the relevant comparison is the 997 GTS which has the same drivetrain (as does any 997.2 Carrera S with the powerkit).
This may be a bit of a tangent, but since we're discussing wings, spoilers, drag, etc., don't suppose anyone knows the aero impact of the Carrera Wing? Whether with or without the spoiler lip (for later cars), or - assuming it's the same wing on the blue car in the brochure page posted by Hardtailer - with or without the blue car's bumper on earlier cars? (In other words the impact on drag, top speed (or whether there is an impact), and also on lift.)
(I assume it's the same wing on the blue car, no? And the bumper looks just like the GT aerokit's bumper (not shown). Anyone know if it is?)
(We probably at least know the direction of the impact on lift (less rear lift), though not the amount. (Because Porsche packages the wing with a front spoiler lip (for later cars), and the bumper on the blue car (for earlier cars).))
Porsche offers the aero kit front with a full width lip underneath with both
-rear cup wing
-rear fixed carrera wing
.
Hi Hardtailer, any chance you could post a higher quality image of this picture (form an old TEquipment brochure?)? Or alternately, could you let us know the part number for the later version of the Carrera Rear Spoiler (the version with the front lip)?
Porsche now shows the Carrera Rear Spoiler on the Porsche Classic part of it's website, though with no price shown. They only seem to show the version without the lip spoiler (part number 996 512 903 00 G2X, probably the same as in the above image, I think, though I can't make out all the digits, no matter how much I enlarge it). They seem to imply it works on all 996s, not just earlier ones. (Pre-facelift, I presume. Can't make out the dates above.) And they again say there are aero benefits. ("enhances ... aerodynamics. ... [and] ... optimising handling.") Seems to suggest less lift (or handling benefits are from less weight and better weight distribution?), though no mention of drag.
