Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am looking at starting my own possible project, with the aim to see how LIGHTWEIGHT one can be made. Trying to find out as much information about what is actually possible. Has anyone done this to either a 996.2 GT3 or a 997.2 GT3? Of note: Air-conditioning will always remain in the car! Fully fueled, how low can one get the weight?

POST 2 / ORIGINAL POSTEROriginal post

I keep track of as much REAL weighs of cars, and most of the data is from the best car magazine, the German SportAuto. They test the cars properly, even the setup. And produce actually weights, FULLY FUELED. Hence in brackets the fuel tank size, especially important since 90ltrs is an option on GT3’s. thought it of interest to all. So here are the Porsche ones. Obviously spec also has an effect. Porsche GT4 (54ltr) = 1,379kg Porsche Boxster Spyder (54ltr) = 1,337kg Porsche 996.2 (64ltr) = 1,467kg Porsche 997.2 Carrera (65ltr) = 1,486kg Porsche 997.2 Carrera S (65ltr) = 1,450kg Porsche 996.2 GT3 (89ltr) = 1,420kg Porsche 996.2 GT3RS (89ltr) = 1,373kg Porsche 997.1 GT3RS (90ltr) = 1,424kg (3.6l) Porsche 997.2 GT3RS (67ltr) = 1,417kg (3.8l) Porsche 997.3 GR3RS (67ltr) = 1,388kg (4.0l) Porsche 997.2 GT2RS (90ltr) = 1,405kg Porsche 991 GT3 = 1,448kg Porsche 991 GT3RS (64tr) = 1,461kg Porsche 991.2 GTS (67ltr) = 1,495kg Porsche 991.2 GT3 PDK (64ltr) = 1,492kg Porsche 991.2 GT3 Manual (64ltr) = 1,445kg Porsche 991.2 GT3RS = 1,443kg Porsche 991.2 GT2RS (90ltr) = 1,521kg Porsche 991.3 GT3RS (64ltr) = 1,460kg Porsche 991.1 “R” (64ltr) = 1,381kg (no AC, no PCM!)

POST 3 / ORIGINAL POSTEROriginal post

I see this ended up in the 996 rather than the 996 GT3 section .... I guess I have to make a new thread in the correct place.

Pointless commentary: I like the build/idea, I do not like the red bumpers. I don't understand ditching the radio but leaving in the rear seats/seat belts. That's easy weight to remove and I would have thought would be the first thing to go in a driver focused car. I would much, much rather have the radio than the rear seats. Number of times I have had rear passengers in my 996: Zero Number of times I have listed to the radio in my 996: Every time

POST 7Original post

There's dozens of threads in the GT3 (and turbo) forum regarding weight loss. I'd suggest you start there and then once you have a better idea of what you want to specifically discuss, then start a separate thread, if needed.

appreciate the advise. But be assured that was the first thing I did. Got to page 6. Gave up and started this thread. got any link at hand, if there are so many? its very clear what I�m after. I simply asked one specific question. how lightweight is possible, that has been actually done?

POST 14Original post

How much is possible depends on how creative you are and how deep your pockets are. I don't think many would have though getting a 964 down to 964kg was possible but Jonte is doing it: You Tube If you apply the things that Jonte is doing on his 964 to a 996, there's a lot of room to go further than the CLR build.

I'm on a constant weight loss program with my C2. However, like the builder of the CLR, I have small children and actually use them. I'm sure both he and I would have ditched them if we didn't need them. In fact, if it wasn't for needing four seats I would be driving a Lotus rather than a Porsche because I have a thing for light cars.

POST 17Original post

Here's my spreadsheet. I need to change the color for verified weights vs sourced from the internet (most often wrong). Ignore the price/cost column as that I haven't really updated that. If it's orange font, that is not implemented (same for if it doesn't have a corner listed in the implemented column).
