GTS 4.0 PDK with PCCB

[stylus427]

Has anyone weighed their car with this spec, or a GT4 4.0 PDK PCCB, would like to know the difference. Harry's Garage weighed a GTS 4.0 Manual Boxter on steel brakes and it was 1280Kg official Porsche spec is 1405Kg???

I expect Harry's measurement is wrong. In my own experience the Porsche published figures are pretty accurate. So a 4.0 GTS with a full tank of fuel etc will be whatever Porsche say minus about 10kg for PCCB given they are smaller rotors than for a gt3.

Think a 4.0 GTS with PCCB might be quite a rare animal. Think they were off the menu for quite some time if I recall correctly

My 981 Spyder with PCCB and so called LWB seats is 1340kg so I’m not sure about the accuracy of the GTS figure.

Please watch the YouTube vid as he show’s the car on the scales TWICE - Porsche Boxter 4.0. My GTS Cayman 4.0 PCCB brakes are 70% lighter than steel brakes, which is more like 30Kg difference not 10Kg. GT4 Brakes, wheels, tyres are bigger plus aero kit all add to the weight. I’m asking if anyone has actually weighed their car as a true comparison to the official figures.

I think there have been a number of anomalous weighings by Harry, I seem to recall people questioning other vehicle weights as well.

I have a Boxster 4.0 GTS with buckets and PCCB, it’s an ex Porsche car someone went mad specifying!

You’re right. I’m just not convinced his scales are accurate given some of the figures quoted in that and other videos. I’ve not weighed a 4.0 GTS myself, but I have weighed several of my own cars and found they are close enough to Porsche’s own DIN numbers with options factored in.

Re PCCB I’ve not seen the 350mm GTS rotors weighed. Have you (ref 70% saving)? I’ve only seen GT3 discs weighed and I think on those it’s something like 4kg per disc saving between PCCB and steel. So I just rounded down a bit to estimate the saving for the smaller discs.

So for OP if you’re looking to estimate the weight of a light weight optioned 4.0 GTS I’d suggest you take DIN minus a sensible estimate for PCCB. Or perhaps ask CG or a company that does corner weights. I’d be interested to hear what you learn :-)

718 GTS PDK PCCB Had the car weighed at Allumy Motorsport yesterday with a very surprising result, they build/run race cars so their equipment is spot-on, this is plus 10Kg of fuel to get a full tank. DIN weight [url]

What are you comparing that with?

Presumably, Porsche quote DIN figs for a basic spec car, and this one is likely to have other options that have added additional weight. Whereas, pccbs, lwt buckets, battery, etc would reduce the quoted weight.

And, are those corner weights deemed acceptable, without the driver?

[kmarshall427]

There’s no added extras that will add weight, apart from PDK gearbox which adds about 30Kg to the original 1405Kg then that is less 25-30Kg for Carbon Ceramic Brakes.
The DIN weight is not including the driver, I don’t know what is acceptable on each corner as my car doesn’t have adjustable suspension.
