Unsprung weight is important. In the most basic terms a lighter wheel/hub/brake combination can have a big impact on handling. My experienced racing mate puts it simply - times the weightloss by three if you are removing mass from the wheels. So I am taking 6kgs out of the weight of my wheels, and 3.6kg from the brakes (see below), for a total of 9.6kg which is effectively nearly 30kgs handling improvement.

I also have a weight limit of 1188kg for me+car. I weigh 100kg. I would like to get the car as close to that as possible - I was 30kg over last year. So removing nearly 10kg gets me closer to the weight limit.

Brakes:
12. Go to the kitchen. Original Cossie caliper with pads weighs 5.3KG (scale has gone right round past zero)


13. Hi Spec brackets and DS3000 pads weigh 1kg


14. Hi Spec calipers weight 2.5kg



Change of calipers saves 1.8kg per wheel in unsprung weight, gives a bigger braking surface area, should diffuse heat quicker and didn't cost too much.
