    Many of our customers in both the GM and Ford segments of our operation, have ride height issues after lowering their vehicles.

    Some very common complaints after lowering vehicles are:

    -Car did not drop much in the rear

    -Car is sitting lop sided

    -Car is making noise now

    -Car feels very unstable and floaty

    -After lowering the car, some of the bushings have worn out


    Many times, it is simply due to not loosening all of the suspension pivot point bolts, and re-torquing them to their specific TA values whent he car is sitting on all (4) wheels/tires - loaded.

    The best way to perform this is get the car on a drive on lift, or blocks or drive on ramps. The car needs to be level and sitting on all 4.

    Loosen all of the suspension pivot point bolts enough to where there is no load on the nuts.

    After ALL of them are loose, go ahead and RE-torque them all to OEM specified values.

    These pivot points are as follows:

    FRONT: (anywhere there are rubber bushings)
    Front Radius Control Arm - inner mount
    Front Lower Control Arm - inner mount

    REAR: (anywhere there are rubber bushings)
    Upper Camber Link - inner and outer mounts
    Toe Link Outer Knuckle Bushing
    Rear Control Arm Front Inner Mount
    Rear Control Arm to Knuckle Mounts


    Hope this helps! Happy Modding!

    This may be a stupid question, but one I do not know the answer to. Should this be done prior to the alignment?

    Kelly to make it the ultimate TIP, please also add the torque values for those bolts. :)

    And I just got an alignment yesterday! I'm looking for something to cure the noises I'm hearing when going over speed bumps and other low speed/high travel situations. This may be the cure

    This should be made a sticky at the top, most people never think about doing any of this!

    I can attest to this. Once my springs were installed the front dropped great but the rear left side did not drop at all. Almost looked higher. Finally found a great alignment shop and when he loosened the LCA bolts the car just dropped. Now the car rides and drives better then it ever did stock with no dive or squat.
    With the suspension parts i have and with the alignment i am very happy with my purchase of BMR parts and will purchase more in the future.

    Again thanks Kelly for the suggestion:headbang:

    Not to mention this unintentional preload is bad on all those rubber parts.

    Edit: All four corners of my brand new car were not equal on Day 1. Maybe my car was trying to tell me "Wrench on me!", lol.

    I did all of these things when I did my BMR install and I have not had any issues. Car sits level, no noises and the car drives wonderfully.

    Tighten it until it breaks, then back it off half a turn. Works like magic every time!

    Any pic of where these exact nuts/bolts are that need to be clocked? I don't want to just start jacking with stuff.

    Taking my car in for an alignment Monday, Hoping the guy lets me get under there and clock the bushing before alignment. Have no other way of doing it and having the car level.
