As has been said, nope. But many 2.5's have been fitted with a Q2 or Quaife torsen type limited slip diff as the gears inside the diff are a weak point. More so on the GTA but there have been instances where a 2.5's diff has gone pop.
Yep if your 2.5 is in fine health they can pop the diffs. Mine went when turning onto my driveway after a trackday at Mallory, luckily I only live down the road and as it went at low speed it didnt ruin my gearbox.
Thanks all. The current series I'm competing in doesn't allow a LSD if that model didn't have one as standard, so I'll have to keep taking my chances. I try to be not too aggressive on the launches and use good quality fluids.
