    People have told me that during hard acceleration my Gxp looks too saggy. Any way to reduce this? Is this a sign of bad springs or struts or is this normal?

    I think its just the way it behaves under acceleration. Not much you can do I don't think.

    If you're not building a racecar, I wouldn't bother with it. The exception would be if there is sag when parked. That would indicate that struts need replaced.

    If you are building a racecar, get taller stiffer struts and springs in the back and shorter struts up front. This will help keep the momentum forward when launching. There's a cable mod you can do at the track that has some proven results as well, but you don't want to daily drive with it for safety reasons.

    Thanks for the input. Those springs look like they would work. Has anyone tried them.

    Would raise the back up it would look funny. Sag is gonna happen no matter what not much you can do. Its not hurting anything unless you looking for better 1/4 mile times

    It's FWD, front goes up, rear goes down upon heavy throttle.

    Same with RWD, the rear will squat down.

    Otherwise the car will ride at a levelish ride height all the time, so for the very very little time you are whomping on it, does it matter?????

    Nope.
