i got a guy whos bent 2 drive shafts.

the car is a ls1 f body. he is the original owner, road races but doesnt drag race. the car is pretty much stock.

the first drive shaft bent with original suspension. at speeds of about 220-230 km/h. well some serious vibrations were met.

then it was replaced by a shop with a steel drive shaft for temporary use. tested it, ran fine for a bit at speeds of 220 km/h. then a short while later the vibrations came back.

went to the shop again, it was bent.

the only differenced between the two times was the second time he had some suspension mods done like new konis, relocation brackets, eibach pro kit, aluminum lcas.

now what the hell would cause two drive shafts to bend at speeds of over 220km/h???

thanks for the replies guys.

the fist one he bent was a stock ls1 drive shaft. was replaced by a 3 inch steel one. when he took the steel one back to the shop they told him he over spun it.

as for bushings there all stock. the vibrations only started at over 200 kms so i don't think the tranny mount has a problem. ive had a split one and it shook all the time.

ill mention upgrading the drive shaft.
