18" vs 20" rim size
Discussion
Sure 20" rims look nice but are there any other advantages? Roads near me are full of potholes so I'd be a bit concerned of damaging them like the below:
Anyone gone 20" and regretted it? (I mean if you actually use the car, rather than just keeping it in the garage and cleaning it...
I saw in the Tesla forum (don't ask) the smaller wheel sizes seem to have quite a significant improvement in range, so I did wonder if 18"s had better economy.

Ran both on my Cayman, 18s give a slightly better ride but the 20s look so much better and I think they are slightly lighter.
I have switched back to the 20s recently and I am much more careful of holes and big ruts.
Probably going to be shifting the 18s on now as the car just doesn't look right with them.

Given an identical wheel design in 18" & 20", the 18" will weigh less, because it is made with less metal.
I think you’ll find that might not be the case.Often rolling radius is maintained between wheel sizes and tyres with a higher profile negate any weight saving from the smaller alloy.
That’s been my experience when I’ve weighed my Cayman summer wheels/winter wheels.

I was comparing the weight of the wheels, not the wheels with tyres. Bigger wheels are heavier. A smaller wheel with more added weight may weigh the same as a bigger wheel with less added weight, it may even weigh more, but that's not what I said.Often rolling radius is maintained between wheel sizes and tyres with a higher profile negate any weight saving from the smaller alloy.

What's the point in comparing wheels without tyres? You can't drive your car on wheels without tyres, so there's no reason to compare weights of wheels without tyres unless you're comparing how much metal you get for a particular price.
Doesn't make me wrong though, does it?Same wheels, same profile/ width tyres in two different sizes, the smaller one will be lighter.
You can fit 18's over the big brakes on the GTS 4.0 as I have 18s as my winter set.
Sadly I think it's just the poor condition of our roads that are to blame however there may be a compen case with your local council if they fail to maintain a road which then leads to damage of a vehicle.
