mfg Posted 14 hours ago Report Posted 14 hours ago The 1963 Studebaker Avanti built in roll bar was considered, at that time, to be…..?…. stronger than the minimum requirement set by USAC for roll bars. 1) 75%……2) 140%……3) 175%…..or……4) 200%
Stacey Posted 14 hours ago Report Posted 14 hours ago In 1963 lets say if they were #1. 75% better that would be a huge improvement. So #1 is my guess.
