Put a magnet on it. If it doesn't stick, its ali.

But if its lightweight, its 99% an ali one. They're stupid light.

on my old clio i had a carbon one and this 172 one feels pretty light too! soo im guessing!
il have a look tomorrow

You'll know straight away by lifting it... The alu is VERY light compared to standard.

I had one on mine without realising it, unless Jesus pointed it out and I tried lifting his. Massive difference!

lol
il soon find out!

the ally one is ridiculously light, oh and if you're unsure just don't be a muppet and close it thumbs down you'll dent it. Let it drop

I think that my Clio III bonnet is Al because the only place I can stick the magnet from my Fluke 289 is on the bonnet catch for closing it. The rest does not stick the magnet. Was a pain in the ass when I had done some logging to the alternator output to find a suitable spot for it. If its not Al is probably some lightweight alloy.

the second you lift it you will be able to tell, if i remember rightly the ally bonnets are nearly as light if not lighter than the carbon fiber ones (i know the one on my phase 1 feels like paper when lifting it). there was a thread ages ago that a bloke had weighed the 2.
