Is this suspension sag?
 

After looking at several shots of the 350, (promotional shots) i decided that my car appeared lower.

I measured up the fender height against the FSM and both front and rear are about a half inch lower than it should be.

I don't know what brand the stock shocks/springs are, so i can't tell if they've been replaced. The car has a little over 70k miles on it now and i'm wondering about their condition.

At 70k miles, you've probably got a combination of damper wear, bushing wear, and spring sag.

Half an inch a corners worth?

Hmm.

I was thinking of doing the dampers at some point, but i need to buy the whiteline rear diff kit first :(

Measurements will be inaccurate because:

How do you measure with a tape and assure that the tape is perpendicular to the ground.

FSM is measured how? Dry weight? Curb wight? Simulated driver and passenger?

Tires. Are you running OEM tires?


Have you ever held a tape to the wheel arch from the floor? you won't find half an inch by moving it off center.

Unladen is the condition measured, in the FSM it states that as all fluids full and all tool kit etc in the car.

Yes, original tyre size, FSM even states difference measurements for the 17's Vs the 18 inch wheels.
