Full carbon body Time Attack Supra
Discussion
Don't get the point of replacing the panels with carbon - there will be minimal weight saving (if any - 2mm carbon panels may actually add weight over thin steel sheet), and it'll be a nightmare in a crash - possibly even dangerous. If say it rolled, rather than deform the carbon would shatter. The shards would do some serious damage. If the chassis was an optimised Carbon monocoque, with the laminate planned where the strength was need it would be great, but simply hanging carbon panels off a steel frame is just a pointless waste of money.

Is it just me that thinks this is actually quite silly?? Even on slicks its not going to be particularily tractable? Doesnt look like it was running any trick tyres before, so it must be slower than stock as surely the power just spins away?
You don't have to use all the power all the time, but when you can 
I was going to post some concerns about the honeycombless-carbon roof, lost structural rigitidy yadda yadda yadda....then I saw the roll cage 
It looks awesome, but I have to agree with what some others have said, I just don't see the point in replacing those panels with carbon. Making carbon doors, bonnet, boot lid and front wings definitely make sense. Anything that needs to be cut from the main shell, errr no.
However it looks like it's gonna be a mega car, albeit a bit on the scary side

Right, nice effort but!!!!
20kg's to be lost from the front slam panel, inner wing guards, Don't forget these cars run a front subframe, so front of inner guards can completely almost go. Another 20kgs to lose by removing the boot floor & fuel tank, 8 kgs per rear boot pocket.
Bare doors weigh about 55kg each, outer skin & bit of frame sub 25kg's rear boot will be about the same.
There's a twin wall fire wall up front too
If going mega cage then roof structure is triple skin on the frame work
Rear subframe bushes & bolts weigh 16-17 kg
10kg to be lost by simply deleting superfluous bracketry from inside
My Z20 Soarer has gone from a 1650kg wet weight road car to 1130kg full on drift car, not a carbon panel in sight (yet)
