I installled the cognito 4'' lift yesterday. Overall it was pretty easy. We had a few issues:
a) The front driverside differential mount didnt fit onto the differential properly. Slight modification and off we went.
b) Alignment was severly off. We had to adjust the toe-out b/c it wasnt even driveable.
The negative camber was expected due to the tightening of the torsion bars. But wasn't significant.
I dont have my wheels and tires yet but the ride after the lift install seemed better than stock.
I will be getting my wheels and tires tomorrow and post some pictures.
