Well, the thicker rotors are more massive and arguably better for durability and performance.

So, if you cared to step up to big rotors, you'd need the spindles, rotors, bearings and seals. You'd just have to ask yourself if the perceived advantage is worth the cost.

If not, you can buy the spindles for thin rotors and run your thin rotors and such that you already own.

Is the extra expense worth it to you ?
