Solution, available in two different sizes: http://www.tempurpedic.com/cushions/...barcushion.asp. I've never used the lumbar support on any cars I've owned or driven that had it available, so I doubt this will be an issue for me, but somebody mentioned this elsewhere and I was glad to see that there was a simple, effective, and relatively inexpensive mod to make LWBs more serviceable on a day to day basis if needed.

Thanks - that one looks good. I had considered this inflatable one for Euro Delivery, since it would be super easy to pack in luggage uninflated and might be good on the plane too:

I need to test drive some of these various supports...

Well most things are possible for a price. I think it's a little unfair for people to be so thrilled at the much lower than expected price AND miffed that the car doesn't have more power. I understand that a base price $20K higher wouldn't even raise an eyebrow for some here and that they therefore may have preferred Porsche had gone that route, but the explanation of the necessarily more restrictive intake and exhaust designs on the Cayman causing some horsepower to be lost over the same engine in the 991S seems plausible to me. Could it be designed around? Possibly, even likely, and if so it sounds like BGB may well be the people to figure out how -- but if they do, I'll be very interested in their assessment of how much more it would have cost Porsche to build that configuration at the factory and any aesthetic or other tradeoffs that achieving the extra horsepower required.

Honestly I think the horsepower restriction is more about keeping the cost of the car down than preserving a hierarchy. If money had been no object on this car, Porsche could have designed for it a custom engine between the 9A1 and the GT3-modified version, a rear multi-link suspension that would have fit, shorter gear ratios including the ones on the mainshaft, maybe an e-diff that doesn't require a PDK pump to drive it, etc. But then it wouldn't have the base price that it does.

The intake and exhaust are marketing BS,trust me,I've been following Porsche for a while. It wouldn't have costed Porsche anything,but it would've gotten way too close to the GT3's performance level and they couldn't have built a GT4RS.

Hmm, ok. Well I'm the newbie here so I'm happy to defer to higher authorities, but out of curiosity, are you implying that significantly more horsepower is possible with the existing intake and exhaust setup and that this engine is just limited by its ECU tune, or that they somehow intentionally restricted the intake and exhaust in ways they didn't have to? The latter seems like it would be pretty obvious to someone knowledgeable who tore into the car to take a look.

This engine can be had with the Powerkit option from Porsche,which increases power from 400HP to 430HP. Porsche is stating that they couldn't use the same intake found in the Powerkit on the GT4 because of clearance issues. I highly doubt that. I'm sure BGB has a lot more experience since they've been doing Cayman conversions for a while now.
