I've got a versailles 9" in my car, and now that I'm getting more into drag racing, I've been ditching a lot of weight. That versailles rear weighs a friggin ton. I like the heavy duty housing and I have a good center section and axles, but what I'd really like to do is get rid of those ridiculously heavy brakes. I bet I could free up 40 lbs by going with a unvented rotor and a more modern style aluminum caliper. Anybody ever switched one over? I'm kinda worried I'll have to buy new axles since the rotor depth probably won't be the same.

Ya, they are heavy.
I would contact bare, SSBC or wildwood and see if they have a retro-kit for that rear....
Would be a lot lighter and mucho cool.

And oh yeah, the caliper in their picture is not at the top of the rotor,
I called them about it being in "the worst possible position"........

Why would it be so bad if the caliper was at the top of the rotor? No matter where you put the caliper, it will still put the exact same torque on the axle...

Motorhead-
I can appreciate that the torque from the caliper
is the same no matter where the caliper is located
(clocked) on the rotor. May be a bit of a trick bleeding
a caliper that is at the top of the rotor however.......
To say nothing aboiut what that caliper is going to run
into when the car comes down on top of the axle.

Doesn't that wilwood rear setup use a 12.something"
rotor? Having that much rear brake capability might
be a bit of a challenge trying to keep it from locking
up. Even with an adjustable proportioning valve dialed
all the way so the bias is on the front, the rear brake
will lock, in my experience. I guess you could use two
prop valves in a row

Why change from vent rotor to unvented? You are driving on the street, right? Unvented disk will retain heat more, after repeated use...at least that's my guess.

yeah, I just noticed that the rotors are 12.19" diameter. I'll have to check that out. I think the versailes rotors are 10.5" or so. I'll also ask about the weight differemce between solid vs vented, it was my understanding that solid rotors would be lighter. Late model mustangs use solid rear rotors, as do a lot of other cars and they seem to stop fine with no fade, unless you are really flogging the brakes.

I also need to price out a kit like Bill's that has the aluminum hat and a thinner rotor.

Versailles are 10.5-inch
Full size lincoln (similarly designed rear disc system) are 11-inch.
Only the rotors interchange, nothing else.

66GT289,

When you say the full size Lincoln rotors interchange with the Versailles ones, do you mean you can put those larger rotors on the same setup as the Versailles? I mean just simply put the larger rotors on in place of the smaller ones?

Yeah, I think the full size Lincoln was a 5 on 5 bolt
pattern, come to think of it....
The rotors were definitely 11-inch vs. 10.5 on the
Versailles.
To use the larger rotors, I think you have take care
of the bolt pattern situation and also use the Lincoln
bracketry. The caliper itself has a different piston
diameter (larger dia on the Versailles) but either
caliper will physically fit and slide correctly in the
full-size Lincoln caliper frame. (the caliper frame may
even be the same part number between the two cars,
I've never checked it out)
