What is the farthest they have been pushed without failure? I have a 2003 6spd EGR delete with 175/75, MTW hybrid, RR, Matt's tunes I run only the SLR tune and a FICM tuneby PHP. Been running this setup for about 20k towing and lots of hyw with no issues and those are hard miles. I will be installing 225's and a stage 4 soon and studs cause I'm not completely crazy. But it would be nice to see how far I could push them stock bolts.
