Good job doob! Those pretty much match what I have in my books dead nuts.

Note: Those specs are for factory components. Some aftermarket parts will require different torque specs.

I would add that all the A-arm & rear suspension hardware should be torqued with the car on the ground, or at least with the tires at ride height, unless you have Delalum bushings or spherical bearings.
