Ok I stand corrected, holy those are some heavy rotors. Maybe it's the hats, because another 20mm up front can't possibly be the sole cause of 2kg increase. Like this is significant weight.
Otherwise, the weight wasn't as bad as I thought seeing most of it can be removed without too much issue. (Seats can be replaced with fixed back buckets, and exhaust will probably be swapped out by most).
