Calling all circuit racers..

[Daz570]

have been sitting here for the last half hour trying to figure out these pictures, in the class the car runs, it isn't allowed a pannard bar (basically the same example of car ran with is allowed although can be modified or a different strength etc..) so i'm trying to figure the rhs (square framework painted pink) out??

can anyone elaborate?

C'mon guys... this is one of the better handling A bodies in the class, there could be something in this for all of us..

It would help to know what type of racing we are talking about.( road racing, circle track )But from the setup, and the marks on the sway bar. I would have to say its to keep the rear end out of the fuel cell. Just look at the marks on it,and see how much the sway bar moves, the rear has hit it more than once. I'm sure it helps ty in the rear frame also.

the car is set up for historic touring circuits (you know, the ones with all the corners) bathurst, sandown, winton, symmons plains etc,

just pulled this from an aussie forum which sheds some light on the topic

note the vertical slot in the 'pink bit' on the side facing the diff housing - my bet is there is a pin fitted to the back of the diff that fits into this slot. As the diff moves up and down, the pin will move up and down in the slot, keeping the diff centred - a form of lateral locator that has obviously been used to get around rules that don't allow a Watts Link or Panhard Rod to be added. Being a Borg Warner diff, and seeing as the slot is offset slightly to the right of the diff centre, my guess is they are using a cast alloy diff cover from a Watts-Link equipped Falcon, as they have a Watts Link pivot pin fitted to the cover in just that location.

It's a slider setup. Behaves like a Watts Link but cruder, more friction, less potential travel. Has a pin/bearing in the center rear center section itself. The point becomes the rear roll center. The slider mount/track is firmly mounted to the chassis. The pin can only slide vertical in the mount. You need to make a heavy reinforced center mount to react to all the force of the pin.

Yep, I've seen one in C-Prepared SCCA autocross class. It was in a 65/66 Mustang in Iowa. My pictures of it are on film. But it looks like the one you posted. I think Frank Stagnaro in San Fransisco runs the same setup in his C-Prepared 65/66 Mustang.
