Where exactly were these? I'm curious if there are any on the Gen 3 I could remove; I haven't noticed any so far.

Hi, two were underneath on the chassis and one was under the front bumper, I don't know if theres any behind the rear bumper

I wont get time to check this year...

Ive decided to do the bonnet as well. Not sure theres time in a week but am going to try a tidy and respray while I'm at it. It's may look hideous but rather than a homestyle chip foose kind of thing to just have line to break it up

And carmine red, a brighter red

It should'nt flex once properly cured but making a light frame to support it

Questions
You are making a composite/fiberglass Hood/Bonnet? Yeah
I have consider doing this process However I am unsure of the know/how/DIY

There are obviously different weights/thread count/weave thickness to choose/use?
The resins seem tricky also to me as well?
How do you remove that cast (carefully for sure) without sticking to Hood/Bonnet?

Thanks in advance

How much of the aluminum would you say you have replaced with carbon fiber?

Some sports cars have carbon fiber wheels...if the owner has an extra $25,000 to spare.

Thanks, I'm still getting used to it, I've used four sheets of 200g so 1000g altogether

Depending on the strenth I will add more sheets/braces

Heres casting two small ones. Theyre glued on now

I use cling film but you can use wax. There's three resins, polyester, vinylester and epoxy. I've used all three and don't think theres an awful difference. Epoxy is hardest and doesn't smell as much

I use 200g because it's easy to use and costs less. Woven glass is a very good substitute

I think the alloy bonnet is around 7kg at a guess. I don't have much more time but plan something with the doors, wings and hatch next year

Thank you Nathan and I like your build and thread

Any fuel economy updates?

I believe I've said this before, but I personally have found any reasonable weight reductions to only improve acceleration, and that the fuel economy savings basically disappear into background noise.
