My T/A is setup for national competition SCCA Solo/autocross events (SCCA class E/Street Prepared)... been very succesful thruoughout late 70s-80-90s (I've taken the past ~10 years off for family matters; now coming out a little for "social" fun over the past ~3-4 years). I have custom-made solid sway bars mounting in the factory locations: 1.25" front, 1" rear. I also do "social" lapping hi-speed road course events.. these big bars are no problem... car handles very flat and very neutral through the turns/curves, etc. My custom sway bars were made by a past semi-professional SCCA TransAM road racer in the late 70s... that's how they made them in the past... regular bar-stock steel, heat.. bend, etc. I've recently considered getting one of the new "hollow" 1.25" front sway bars for weight saving, maybe a little thicker than 1.25, say perhaps 1.375" diameter, and then 1.125" for the rear.. and making the rear adjustable. Any of the current sway bar mfgrs shhould be able to make any diameter sway bar.. duplicating the same factory shape. The frame-hung rear design (stock configuration) is better than the axle-hung designs. The front opening through the k-frame can be a little tight... 1.25" diameter is tight and will fit.. anything larger is tighter to fit and may require some stretching the path through the k-frame.
