Back in the day Tri City "Launcher Springs" were GM copies of the Mopar Super Stock springs and the choice of most of the NHRA Stockers before Cal Tracs came out. My 78 TA 6o ft'd 1.51s it he them with a 10.90 time slip. I had a small 5/8" factory rear sway bar on it. They worked really good but were stiff and heavy.
The IA Camaro has Split Leaf and Cal Trac bars. Factory rear bar was too close to the 12 bolt's rear cover/brace so I used a Second Gen Pro Touring rear bar with a little longer "legs".
Not as fast yet as some of these other guys .
