Lifting the back of the car 1" will move the CG forward by 0.36", which will shift about 11lbs from the rear to the front.

So yeah, not zero, but also probably not significant in the context of a 3500lb car.
Agreed, the only effect I saw was the slight Cg forward displacement from the tilting, hence why I specified "significant". However, my napkin gives me half your number using your assumptions (0.18" forward for ~6lb or 0.3%). But I think we can agree that it is not significant .
