Does you auto trans Vette crouch?
I've noticed that the vette "Crouches" when I shift to drive. the back of the car physically settles what seems like a couple of inches is this normal?

hi, i think it is normal. my 81 crouched a good inch when i put it in drive. but then it did crouched even more when i rebuilt the engine, about 2 inchs. i think it just has to do with the torqe on the rear axel. but you cant complian about it, i thought it was bad butt to feel it crouch, made it seem like there was more power there. hope this helps :chevy

When you put it in gear with an automatic or engage the clutch on a standard the pinion gear in the differential starts to climb the ring gear. Since the car has independent rear suspension (flexible in the center) it pulls the differential down. Thus the squat.

Yea they all do that/ It's actually a design problem with IRS.
With a normal live axle they can design in anti squat so when you get on it the torque of the Diff causes the rear end to lift canceling the tendency to he back of the car to sink due to weight transfer.
With an IRS, and the rigidly mounted diff you can't build in Anti squat.
( if you ever ride in a rear wheel drive solid axle car they do the exact oppisite of the Vette)

'77 does it. I think it's awesome.
Somebody has a sig pic of a launch from the lights. That's an awesome pic with some serious squat. Great weight transfer.
