    I have had my car lowered on SSCs now for about 8 months and the only thing i really noticed in change was a vibration at wot at very high speeds only. Only happens at around 110 km/h or 68 mph. When i hit it going this fast i get vibration. Would installing shorter dogbones help this?

    why would it only vibrate at high speeds and wot?

    thanks

    How are your engine mounts? Did you install some pogo washer and instead of shorter dogbones get some Vinnie spacers.
    Squirrels are my engine. I need a Ford Regal

    didn't really check the engine mounts, car only has 70 000 miles on it. I installed 4 pogo washers with the install, nothing else.

    Motor mount spacers is what I would do to correct the axle geometry from lowering.
