I have this really bad virbration right around 35 to 40 mph doesnt matter what gear. it gets worse with more throttle. in 2nd gear it will rattle the glovebox open lol. i have replaced the axles. i am positive it is not the axles. the car is very low i was thinking that the axle plane might be outa wack. any ideas on the axle plane for a civic? any ideas at all would help. im running a gear speed trannt with driveline shop axles.

 

How low is the car?

 

just low enough so the front tires tuck under the wheel well. 195/50/15's
