its something with my car but idk whats going on frame is straight and so is everything else. i work at the gm test lab where they did all the ecotec work and they say they ran stock shafts at the track and put 5-600 hp to em and they didnt have problems breaking.. butt im sure there was other factors involved that helped save the shafts.

 

ya thats right I was at the VHF rig as well. pm me the details, mods and pics of ur car I can try to help you./doesnt make sense what is happening to you.

 

sorry i havent sent you a pm of pics i have them on my buddys laptop and he broke it the following day.
