i'm kinda surprised the hood weighs 40lbs. is this maybe an attempt to keep the weight balanced in the car?

Hi guys,
Thinking of my next weight saving,
any one knows if there is any gain weight between the original rear lid with the retractable wing against a fibre glass RSR type,
also thinking of replacing the front fenders with fibreo nes, does anyone knows the difference of weight between the original and fibre glass ones ,
cheers
Konstantin

not worth the money. Spoke to marcus buehler about that and he told me a potential difference of roughly 3 kg per fender.... i would go with CFK doors next :-)

Hi Thilo,
Thank you, so what is the weight saved with CF doors, I also worry about safety without full roll cage, would you have standard size windows or it's a small sliding window like on race cars ?
how about cabin noise ?
The ones from DPmotorsport look great, with all windows flush to the body.
I just upgrade with their plexi quaters and flush to the body rear plexi window, they are great and no additional noise, I am not happy with the rear fit, the guys at the paint shop did not do a perfect job, I will have to have it done again;

Thanks Foxman, interesting , that's quite a lot of weight at the right place, but must admit the Ducktail is not so much my taste, I prefer a narrow version of the RSR (from Getty design) or a tail like on the C4 lightweight race car,
I will ask Getty if they have recorded weights for those.

according to DP motorsport the FRP or Carbon doors are 6.5 kg, would probably need to had , the aluminium frame.
here is a copy of their texte
tempted or not .....

Lightweight doors for Porsche* 911, 935, 964 and 993

available in fibre glass or Carbon

The design of the door allows the usage of the original window frame and offers a custom-fit adjustment of the aluminium frame by long slot readjusting, like for the original metal doors. The door provides ideal clearances with sufficient material to grind in a perfect gap. We also offer the fitting windows made of tempered plexiglass in clear and green, sliding window optional. For street cars, door panels in carbon or imitation leather are available. Total weight incl. window, handle bar and lock from 6,5kg.

Introductory offer:

(pc. without window, lock and handle bar)

Door in carbon: 1427,- EUR incl. 19% VAT

hehehe.
i am in the process of 38kg reduction this winter.
I would go with CFK doors and add a cage to the car. I will add a cage - or more a welded cell - anyway to the car because of safety issues... Noise is no argument in my car. You can't have a talk in my car above downtown speed.... The car is really noisy.. I would go with the "race car" door, that has plexy windows with that small tiny sub-window... Some weeks ago, i missed some CFK porsche doors for small money at ebay not far away from my home...

Next winter, i am planning CFK rear fender and the loss of the rear bumper beam... this should reduce another ~10kg wheigt... Not far away, we have to discuss about the G64.00 box

Hi Thilo ,
Great news ! you are really on a mission , inspiring for all of us !
The bumper itself is 5kg, would be great to have them made in FRP or carbon, as I remember, I think FDV have them , at a quite height price.
That's good you go for the roll cage, for the CF doors, I forgot the original ones are weighting so much !
not sure if the CF doors a good idea without a rool cage for my car , so tempted since DP sales them for fitting with the originale window frame ,
Regarding the box, personally I am not sure yet to convert it, looking at the number of times it rains, I may bare with the 65kg.
Jack as done an amazing job with the locking collar, and all the tests, he is still testing the ability of the PDSA versus fitting an LSD, can't wait to hear from him.
