I have just had delivered a fibreglass bonnet for a Riley Elf. Bought from ABS motorsport, only ordered on Thursday evening and arrived today. The bonnet is very light and on first look is good. No bashed corners etc as it came in a massive box!!
The only down side is that ABS don't do a boot for an Elf/Hornet, so I have ordered a carbon fibre one from Carbon Weasel. I'll report back on that when it arrives at the end of Feb.
