The only bushing I have in the front is poly and its in the lower control arm. Rides better on the road and leaves much better on the track. 68 Barracuda Formula S 340

Worked great after that.. 5.53 @ 125 1/8th on the launch control..more left in her!

He just redid the front end last month with poly parts. After about 200 miles it has developed a loud and annoying squeeeek coming from both side's upper control arms. Decisions decisions...
