    I’ve done a frame off restoration on a 70 GS 455 convertible. With the body back on, the front of the vehicle is sitting too high. I thought it was settle down when I put the motor and transmission in it but it has not. Used OEM front springs when I did my front suspension. Any ideas or suggestions on how to get the front end down, or should I change the springs and put 2 inch lowering springs on it. Thanks in advance for any help

    Drive it,..it will settle and were the bushings tightened down before the engine and body were set back on?

    How did you tighten the suspension bolts??? With the car sitting with no engine??? IF you tightened them up with the suspension hanging that could be a reason. Try loosening all the suspension bolts & with the weight of the engine, trans. etc. the nose should come down.

    Did you "locate" the springs in the upper pocket properly?

    I cut one coil from each of my springs to achieve desired ride height.

    There's still a lot of meat left to go back on that car. I'd worry less about ride height right now...then reassess when it's 100% together.

    As stated above, the front upper and lower control arm bolts should not be tightened until all the parts are back on the vehicle.

    Yes, with springs "in the pockets" and full weight on all 4 wheels, loosen the bushings a little and bounce the front end a few times. Then retighten all bushings.
    Expect new springs to settle a little with age and road use.
