Hi KODAKHODAK,Hey Guys, does anyone know if the 19RCS Corsacorta would fit on the V4S? from what I can see its suitable to suit from the WRS websiteWRS Italy RCS19
If your brake caliper piston size is all 30mm, meaning 4 pistons each 30mm diameter like the stock caliper, Stylema caliper, Stylema R caliper, or GP4-MS caliper, then you need RCS17 Corsa Corta.
But as soon as your brake caliper has 2 pistons (out of 4 pistons) larger than 30mm in diameter, then you will need the larger RCS19 Corsa Corta.
You can use the RCS19 Corsa Corta on the stock 30mm piston caliper, but your master cylinder brake lever will have almost no free travel and leave you with less "feeling". (people called it woody feeling/too hard)
