I know people use spacers to push the wheel out to clear brakes but do they have shallower and maybe lighter rotors to tuck wheels IN and reduce unsprung rotational mass?

I love my wheels but they are heavy and the offset isn't a lot so the rears at least could use to be pulled in just a little.

Is there such a thing? Winter project is to pull calipers and re-paint, SS Brake Lines and maybe "add some lightness".

Seriously considering taking out the spare tire but I am just asking for trouble at that point I think as it's been 11 years without ever having needed it! My amp currently is in the spare tire. I press fit a board to mount the amp to in there. Anyone have an old amp board that they want to get rid of that fits that spare tire spot?

 

A shallower hat on the rotor would only serve to move the braking surface of the rotor closer to the wheel... This wouldn't be feasible without a new caliper bracket but it wouldn't accomplish what you're looking to do.

I've never seen a way to move the wheel itself further inboard without machining the hub of the wheel to change the offset.

 

Get some 3 piece wheels from CCW. He can give you any offset, size you want. Just about ALL the cars in the Grand-Am Series, Continental Tire Series and the production based cars from the ALMS use his wheelr. I had a set on a full race Camaro that were perfect!

 

Maybe I am not explaining it right. You get a rotor it sits on the hub and the tire squishes the rotor to the hub. The rotor has a thickness to it and was hoping to get one with a thinner area that gets squished this way to move the tire inward but not interfere with where the rotor spins though the brake caliper.

Likely there ISN'T a rotor out there that does this. Had to ask.

 

None .... you would be risking strengh for fitment. I would rather have the wide stance

 

Ok so I guess that's out.

What about lighter rotors? Look to reduce the rotating mass. I love my rims and the Falcon RT615K tires I haven't been convinced of a better summer tire! Grip is amazing.

Suggestions on either are welcome so I can research. THX!

 

reducing mass will adversely affect their ability to sync the waste heat from the brakes unless you did some really clever engineering.
with heat comes fade. to lose mass they would also have to be thinner and would be much more prone to warping.

You may not want to hear it, but I think they did an exceptional job balancing the engineering trade-offs on the front brakes.
first and foremost they stop incredibly well and have remarkably good wear unless your tracking it.
These aren't huge rotors either, compared to the front rotors on my two benzes which weigh 25 lbs, EACH!!!
