It was more a general question, so please apologise for me, I'm sure that she is just "big boned"

Fat drivers and passengers are sprung weight
That doesn't answer my question. We already know that a complete set of 4 wheels saves 8.5 kg over standard alloys (according to Porsche marketing blurb), but I want to know what the standard Turbo S wheels actually weigh, so we can judge if it's an impressive achievement or not. If the standard wheels are heavy (and I'll bet they are based on the example OEM weights you have quoted above) then a decent quality set of forged OZ's or similar wheels will probably save 20% or more too.Dandock wrote: βWed Aug 23, 2017 6:34 pm Porsche claims the carbon-fiber wheels are 19 pounds, or 20 percent, lighter than the alloy wheels they would be replacing, which amounts to a nearly 75-pound weight reduction. Theyβre also said to be 20 percent stronger than Porscheβs regular alloys.
Well, you did ask.

My buddy John over at The Wheel Enhancement helped me out on this subject. I know that some of you guys/gals are dying to know actual weights. A big thanks to him for getting the info to us. http://wheelenhancement.com/
Here is what John had forwarded to me.
19β Base Wheel
8.5βx19β = 22lbs 11oz
11β x 19β = 27lbs 5oz
20β Carrera S Wheel
8.5β x 20β 23lbs 10oz
11β x 20 27lbs 12oz
20β Design Wheel
8.5"x20" 24lbs 11oz
11"x20" 30lbs 4oz
20β Classic Wheel
8.5"x20" 24lbs 3oz
11"x20" 28lbs 4oz
20β Sport Techno Wheel
9"x20" 27lbs 2oz
11.5"x20" 31lbs 1oz
Yes, much simpler and cheaper - basically just moulded. Not even in F1 is a carbon wheel considered viable, yet they use carbon chassis and suspension components routinely. Wet carbon layups are all very labour intensive. To make a wheel in carbon is not really viable with traditional carbon production methods, hence why Porsche have had to develop special machines at no doubt great expense. Are we going to see carbon wheels across the Porsche range soon? I seriously doubt it. Will they use this technology for something else, possibly outside of the automotive world? Quite probably.
Teams buy their own wheels - invariably supplied by aftermarket wheel suppliers. When I was involved, a team needed to buy 100 sets per season, but that was back in the day when there was no restriction in usage or tyre blankets (so you would routinely have 10 sets of wheels in blankets ready to go). But if we go with say 50 sets at Β£16K a set, that's only Β£800K on wheels and you would surely get a discount on volume. Peanuts in F1 terms.Kasfranks99 wrote: βWed Aug 23, 2017 6:40 pm I would assume carbon wheels are not used in f1 because of the costs?
They need a hell of a lot of wheels just for 1 race.
Just a thought.

What team(s) were you involved with Peteski?

Yes they will be heavy for sure, but you won't even notice or care. Otherwise you would go with 18s or 19s and save a fair bit of weight in the process.
BAR, Honda, Jaguar, Red Bull, Williams at various points. Been totally out of it for 8 years now.
