I just picked up another s2k. A 2001 ap1 with about 90k.

Anyway its only under hard accelration but the whole car shakes aka vibrates hella. No weird noises or anything else. On the dyno it didnt do it and under slow accelration it doesnt do it either. The car is currently lowered on some track springs i intend to replace but other than that it is stock minus basic minor BPM. (intake, exhaust).

Anyway, any ideas?

 

maybe try looking about five threads down, something about spacers...........

 

if it's not that, get your alignment, balancing, pressures etc. checked

 

yep, does car pull at all? steering wheel sit crooked? get an alignment, and balancing. If a rim knicks a curb you need a balance, and a tire of balance will shake at high speed.

jack it up, check out your ball joints, tie rods, etc.

 

Classic symptoms in need of halfshaft spacers

 

Okay thanks guys.

It has a new alignment done by previous owner and it drives straight like an arrow. Imma thinkin the halfshafts as well. Im in afghanistan so imma just have my wife take it to the dealership and get it inspected but I wanted to know a more specific idea of the problem before i sent her in to be baffled by honda techs. Thanks ^_^

Ill let yall kno what it is.
