Deliberated for ages about getting the v2s over the m4s, but being a bigger guy, i decided that i needed the extra stopping power.
Weighed them this evening.
203 rotor = 210 grams
160 rotor = 124 grams
Understandably an increase in weight of 86 grams (rolling weight, though)
However the v2s were lighter than the m4s
v2 = 343 grams
m4 = 352 grams
So all in all an increase of 77grams, not as bad as i thought, but hopefully significant stopping power improvement.
Hence a 3month old pair of tech m4s for sale 😉

We where going through this a while ago at mtbr. This is what Hope told me too, if you add braided hoses to the M4 then it will be heavier (not taking rotors into account).
You have the vented rotors? With floating ones the difference could be quite a bit smaller... Let us know if you feel you loose a lot of modulation.
