I'm the lucky sap who got to work with Ira at Tarett Engineering and have my car be the test mule for rear swaybar development.

We got a chance to test the prototype rear swaybar at the PCA SDR autocross last weekend.

Here's all the gory details. I felt the need to be wordy so as to help provide and accurate picture.

(The content are my own words. Although I have been given permission to discuss this, I want to make it clear that I am not speaking for Ira.)

Location of the swaybar was an exercise in compromise – Will only racers use these? How stock will people want their cars?

The stock swaybar attaches to pads welded onto the cross member and bends around the transmission mounts. Hollow swaybars are straight, so the normal ‘stock’ position wasn’t too likely. The bar had to either be entirely in behind or forward of the transmission mounts.

With the bar located behind the transmission mount, there were clearance issues because of the muffler heat shield (red arrows). To avoid the head shield, the bar would have to be set up fairly high, necessitating the arms to have a dogleg shape to get back underneath the crossmember. During initial brainstorming there are also issues with ’75 and ’76 cars which have additional gussets for mounting the ugly bumpers (blue arrow).

Locating the bar forward of the crossmember permitted the use less complicated arms. It fits neatly above the transmission.
