Coming from sport bikes, I have noticed that the brakes on my 2015 sportster are not the best. I have seen some rotors on Revzilla that claim a minimum of 30% more stopping power and I thought that it might be a really good upgrade considering the poor braking performance on my bike.

I'm looking at it more so as a safety upgrade and was wondering if anybody else has upgraded their brakes? If so, how much did the breaking performance of your bike increase? I notice a lot of people focus on mods to speed up the bike but slowing down is also pretty important in my opinion. Lastly, would this be worth the money to upgrade or is my money better spent elsewhere? Like I said, I saw these on Revzilla and just thought of it when I saw them.

Floating rotors, 6 piston front & 4 piston rear calipers on my bike.

Will never match the stopping power of my sport bike but it helps.
