5 mm lip

Warren,

It looks like at least the front brakes below have the 5 mm lip as the OP above stated. That might be good for measurement (and rusting) but I can't help but think it would lead to warping?

We have the discs and will make the hats for these earlier models, with 6-8 weeks lead-time.

Weight info:

Front OE 1pc = 37 lbs, RB 2pc = 22 lbs (estd.) Save 15 lbs/rotor
Rear: OE 1pc = 21 lbs, RB 2pc = 13.5 lbs (estd.) Save 7.5 lbs/rotor

Total weight waving per car (for 4 rotors) = 45 lbs

We also like to make our excellent street (ET) and track (XT) pads available to go with these two piece rotors to enhance the overall performance.

The only reason I can think of is the extra margin for error. As the spindle, caliper, rotor, pad can come from different supplier to the motor company, this would assure after assembly the pad still stays inside the rotor than overhung outside the rotor.

They are more seen in European cars especially with Brembo calipers like MB, 5mm in diameter (2-3mm lip) over the actual pad swiping area is very common.

The rusty lip should have nothing to do in warping, but it can help to visualize the rotor wear w/o having to physically measure it.
