I understand that a lot of you guys have lightened your minis by drilling holes in the cross member or doors.
What other panels have you guys drilled holes in to lighten your minis?

What is the purpose of the lightening? Road or track? If you want to go faster, drilling primary structure such as the crossmember is not the way to go as it will reduce the torsional stiffness of the shell and degrade the handling, as well as leading to various other structural and safety problems. Strictly for low mileage track use, not on the road for high mileage. And, I doubt that you will reduce the weight by a pound.
You will save a lot more weight than that by fitting a lightweight alternator and starter, and a racing battery, polycarbonate rear quarter lights (legal behind the driver's sideways sight line) and everything that is not needed. Glassfibre bonnet and boot lid are fairly obvious too. Modern lightweight heater from the kit car suppliers, if you need one. Demister is legal requirement for road use so you probably do. Rewire with modern "thin insulation" wire.
Doing anything to weaken the doors is a bad idea. You don't have much side impact protection and need every bit that you have.

Nope.
Alternative materials yes.
Drillium not worth it.
But as above WHY?

Most people lighten their cars as they put in a heavy steel roll cage. I certainly wouldn't be messing with the structure of an already weak car.

Why not try a gym membership, it may be easier than lightening the car and it will transfer across vehicles.
I certainly have far more excess weight than the mini

The car will be track days really, the reason for asking was that I know that some of you have drilled the doors and cross members but if memory serves me correctly someone did the inner sills as well, but just wanted to confirm this
