Review on K1586 Evolution Drilled Slotted Ceramic by Jim Martin

This kit is priced comparable to other non-slotted/cross-hole kits. I love the value, the extra stopping power they offer and they look amazing. The only downside is that they are significantly louder than regular flat top rotors. Due to the slot and cross-hole design, they produce a "humming" sound under hard braking. However, they're not overly loud, so I don't mind a compromise between volume and performance.
