with a welded diff i guess it wouldnt be as bad as with a diff. i broke several on launch and that split second it takes to get on the clutch it tore  out the brake line put a couple dents in the floor and then lodged itself in the control arm ( azc ) Was a bitch getting everything apart. cant imagine doing that at hiway speeds.  
  
I think if i had stuck with the IRS halfshaft hoops would have been installed for safety
