Considering a GT3 RS in road trim isn't exactly plush inside, where do they find the 170kg to take out of the race car!!! (especially considering about 40kg of cage has to go in???) Shows how much sound deadening and stiffners are in even a pretty racey road car these days
all the legal crap you have to have i.e. airbags and associated computers, wiring etc.
race cars don't tend to have door cards, stereo, aircon, satnav, glove box, carpet etc. etc. (I know the GT3 RS doesn't have all of these before anyone says) but you get the point.
Race cars also usually have Lexan, not glass and Lexan is considerably lighter.

for the first time, it's based on the GT3 RS rather than the 'stock' GT3
Why wasn't it before? Surely it's natural to pick the most hardcore road version when building a racer..
because there is little diff between gt3 and gt3rs....
Sure, so why the change?
IIRC the rs is widebody whilst the vanilla gt3 is narrow body

They don't really, it's probably just a dry weight for the race car vs Euro certified kerb weight for the rpad car. The minimum car weight for the existing model is 1280kg, although it's unusual for them to run at less than 1300kg, which then compares sensibly against the GT3 RS's quoted 1375kg, although some drivers have up to 15-20kg of lead in the car.

In reality, with the same fuel load and driver I doubt there's more than a 50kg difference between the two.

Simple trim doesn't really weigh a huge amount, although airbags and wiring can easily add up. In fact, I'd say the biggest difference between the two cars in weight is probably the doors. Race car doors are carbon fibre and weigh a few kilos (and are eye wateringly expensive if you biff them), whereas I'd suspect the road car items are probably at least 30kg a piece. They probably drop the weight that the cage reintroduces.

I've no idea if Porsche do this, but I should think modifying the wiring loom to have only those needed by the race car could save a few KG over the road car.

If I was to gain nothing else from the thread, just learning this has made reading it all worthwhile.

Is the engine identical to the GT3RS?

Fantastic

And I think it answers the Question: Should you spec the PCCB brakes (£5500) on your new Porker?

Clearly it's a No if Porsche don't even use them on there one make race cars!
Unfortunately, regardless of performance differences, shallow people will not want the cars secondhand that do not have the relevant toys on them.

After watching the 911 Cup cars at two Le Mans races, they certainly are sweet sweet cars.

....No, I still think the GT3 Cup cars sound better... Go and watch them race next season.
