if you had said u were gonna do this 6 months ago i would abeen up for a set,sold the rangie project so no need,
AFAIK MM4x4 are selling GRP panels at the mo

I don't know specifically... but I would imagine that if the bit in question is a registered design, then it would be protected under copyright.


Just a cautionary tale...   we had a 90 in the workshop before Christmas with a 'lightweight' fibre glass bonnet on it....   it was about 30% heavier than the standard Td5 one !   If weight saving is the main reason, it's well worth doing a bit of checking to see if you can actually make an improvement.

i have a GRP bonnet just like that,its about 15/20mm thick  :lol:
also for ARC comp motors if using a GRP bonnet & pannels it has to meet the correct spec for fire retardance <sp>

If you modify the design even by just a little bit you should be OK, worth checking out with a solicitor if you are looking at making a business out of it though! :D

If a design is altered by 10% then it is not a copy.  The fact that it is being made from a different material is enough.

I would be up for a bonnet (at the right price) as mine is v/heavy, dont know why they never made it from ali insted of steel,

Too complex at the time to volume produce - the draw was too deep for the shape and wrinkling was (and still is) a huge problem. More formable alloys, available at the time weren't stiff enough when pressed to do the required job or softened too readily in service and would have required excessive reinforcement. It's quite a big list!.......and it don't end there either!

It was kinda solved on the L322 by the application of huge amounts of wonga.

Back in 1988 a company (now defunct) kindly supplied my Paris-Dakar team with GRP panels for our two Range Rovers by way of a sponsorship deal. They were excellent, such a shame the company went to the wall.

The panels in question were bonnets, front and rear wings, rear quarter panels (the ones that house the light clusters) plus top & bottom tailgates. Somehow they managed to strike a happy balance between strength and lightness, so making the bonnets an absolute joy to use and as for the rear tailgates – they were awesome. Without telling folk about the GRP bottom tailgate, my party trick was to ask people what they thought was different about the tailgate, and when they said they could not see any difference I would jump up and down on the lowered tailgate like a mad thing – then inform them it was made of fibreglass. Nobody ever twigged and of course they were all amazed. The other pleasure was lifting the bonnet with one finger (no exaggeration), extremely handy when totally knackered in the middle of the Sahara!

It can be done therefore, if you have the time, patience and will to get them right ... then market them ... then produce them ...

Question is, are there enough RR Classic owners out there willing to fork out for a lighter bonnet of rust-free tailgate?

Bonnet with light pods built in? 8)  :lol:
Just an idea?
