I bought a set of skunk 2 springs for my 01 S, Installed and had it aligned. Before lowering it, it was a smoth ride, but now, at high revs, mainly 3rd gear and up, im geting bad vibration between 4-7k rpm. IT only does this under acceleration, i can drive normal and get nothing, but the push of the pedal and it shakes all day. My room mate has the same set up, but an inch larger wheel, so im at a loss. Any sugestions? Its really anoying. Any help would be great.

 

start off by checking your tire pressure..check for nails in tires also.

 

ill double check tire pressure, but deff no nails. Its only under acceleration though, i can drive normal and not feel a thing.

 

does anyone have a clue, it feels like something is not balanced, do you think it might be the angle of the rear axles now that im lowered.

 

i am thinking cv joints.

 

Do you have half-shaft spacers? If not, this could be causing the vibration. I like the T1R because they are 2-piece, so all you have to do is loosen the bolts and they slip in. They only cost a little over $100 last time I checked. It's definitely necessary if you are lowered.

 

Your inner CVs are causing the vibration. You can solve by either getting half-shaft spacers (costs $) or by swapping the inner CVs from drivers side to passenger & vis versa (free but takes a little more time).

In a nutshell, the CVs get a wear spot and when you lower a car with a few miles, the bearing in the CV moves just a bit out of the wear spot. The bearing then trammels back and forth from the old wear spot to its new resting spot.

 

how much does the skunk springs lower?

 

they dropped mor then i thought, a little more than an inch and a half

 

how does swaping sides help?
