I'm wondering would there be a noticeable difference if I upgrade the wheels to carbon like Fulcrum Race Zero? These wheels are quite more expensive - would they be worth it? I'm looking for more sporty ride.
Lopping 260g off your wheel weight by moving to Racing Zero Carbon DB would probably improve liveliness and sporty feel, yeah.

Is it worth the cost? Almost certainly not, as there are options which are lighter, deeper, and less expensive, like Winspace Hyper 38, which are around 100g lighter, 8mm deeper, and $600 less than RZ Carbon. Hyper 38s would move your wheel weight savings up to more than 3/4lb.
