Well I have put lot of hard drag runs on my totally stock IRS … the only time had problem with it was the rear end cover at Byron last year it Broke the cover with girdle … caused the problem was the IRS back cover bushing it was very weakened so I change the cover & front bushing with polyurethane...the cover bushing was replaced with solid aluminum I have machined from T6061 solid round aluminum stock & it work awesome...but at same time there is way over 180 runs on this IRS plus over 24000 miles on it..
I do have all my ticket runs for my Owen documentation .. may be I am just lucky will see ..
