Seriously, even if you add 50 Kg of options, that represents 3% extra in the total weight (1500 Kg).
You would need to be a professional track driver to notice the difference.
When we're talking 4WD, yes, that's 90 Kg extra compared to 2WD, mostly at the front, so this could have some impact on the balance. But not on the 0-60 time, due to added traction.
If you're concerned about weight, loose 20 Kg yourself ?
