Some are against using spacers. Some suggest using a different wheel offset to accomplish the same thing. However, that means you can not rotate the tires.

I recall reading something about replacing the ?????????

Is the the rotor?

I tired to do research on this, but with no success because I don't know what this is call.

I hope this pic of a rotor does not mislead the question.

 

You can still rotate your tires of you go with a different offset on all four wheels. Not sure what you're trying to ask regarding rotors.

 

I don't know of anyone using thinner or thicker rotor hats to accommodate a change in offset. To be honest, bolt-on spacers are completely safe for performance use. I don't see why that wouldn't be the option of choice in the matter.

 

There seems to be both sides and voice strongly. Some say spacers are fine. Some say they are not.

 

You can rotate tires just fine with staggered offsets; it is staggered width that you cannot, rather should not, rotate tires on. Offset has no effect on tire rotation.

Spacers are fine as well.

Rotors/rotor hats can account for spacing as well, but you are much better off using spacers or getting wheels in the desired offsets; spacers is the cheapest and easiest route.

 

a spacer is no different than a different rotor hat thickness. at least with a spacer you can still buy hub centric spacers. with a thicker rotor hat, you are going to end up covering the hub bore.

i've never even heard of rotors being made with different hat thickness than the oem it came from. seems extremely silly to me.

 

Yes, true. You can always take the tires off the wheel to rotate.

 

I'm not the only one out there that actually does race on bolt-on spacers. There's actually quite a few guys who do so for autocross, just to offset larger width wheels enough to clear their inner fender liners.
