while some eschew drilled/slotted etc rotors as being bunk, and they may be right,

what about any lightweight rotors for our cars?, (stock sizes)

I haven't had any luck finding any brake upgrades in the stock size. I would like a 4-piston caliper as the sliding calipers that our cars have seem to wear brake pads unevenly, and therefore faster.

No luck, other than the GT500 upgrade which seems overkill.

The only way you should even consider a "lightweight" rotor is if you are talking about a 2 piece rotor w/aluminum hat.

Consider this. A car can stop much faster than it can accelerate. ALL that work is being done by the brakes. A HUGE amount of force and heat is put into the brakes. This is why good rotors are not light. In fact I can tell you that aftermarket rotors that are good quality, weight MORE than OEM's in some cases.

The more mass, the more heat they can absorb with warping be it through more vanes, just thicker friction surfaces, or even different metalurgy that is tougher than something less.

You can have light rotors that are great. See the CCM stuff available on Ferrari's, Porsche's and the new ZR1. Also see the cost.....

Yea some of them cost more than a complete Mustang GT!

Check out the Wilwood 13" kit (part #140-9109). 6-piston calipers instead of 4, but not too insanely priced (~$1700). http://www.wilwood.com/PDF/ds520.pdf

I looked into the 13" Wilwood kit some time ago. Per their template, it wouldn't fit with 17" wheels.

And you have to have the rims to clear them.

"We must warn you, though, that switching to this brake combination requires a minimum of 18-inch rolling stock. Our test subject had the standard 17-inch Bullitt wheels. On the advice of Justin Burcham of JPC Racing, we selected a set of FRPP Shelby wheels (with black accents). He had cautioned us to be careful when shopping for 18-inch wheels. Apparently, not all wheels fit properly over the massive Brembo setup. The four-piston calipers sit out further than other brake kits, so Shelby-specific wheels should be ordered."
