Could stiffening suspension cause chassis/steering vibration?

[sohcsol]

I have spoken to a few people with older cars that had steering wheel vibrations who added a subframe brace bar and said the vibration went away...

Im wondering if its possible that by adding stiffer springs it could be causing more of the vibration from rotating parts to be transferred through the chassis which would cause me to feel the vibration that I have?

I am thinking about trying some sub frame/suspension bracing to see if that helps at all. If anyone has some input on this theory before I drop even more cash into solving this problem I'd be glad to hear it!


Thanks

Tightening your suspension will only cause it to vibrate more. You'll feel more of the bumps on the road, and really feel the road more.

As for idol vibrations etc, suspension shouldn't really make a difference. Really just motor mounts etc.

Thats not quite the type of vibration Im speaking of, let me clarify to say its a vibration related to some sort of rotating part, felt in the steering wheel at certain higher speeds. Feels kind of like if a wheel was out of balance, but theyre not, been over it a dozen times.

So im looking for a reason to buy some of the cusco suspension parts, since the only alternative ive left to try is putting my stock suspension back in to see what happens.

Any ideas?

i had a similar problem,when i changed my springs,it wasn't on my cr-z,but nissan Almera,everything was checked and everything seem fine,but as soon as i hit 90km/h or more (+/-56miles/h or more) the steering started shaking,only when the mechanic took it on the road,did he believe me,and found one of the suspension springs,not tight enough,or missing a bolt,it was long ago,but it was something along those lines...
nothing too serious,but on the long run,it could of been..
Hope this helps

You're going to feel a little bit of a rotating vibration when you're on coilovers and dropped pretty low because the lower you go, the more the tow will be off in the rear and there really isnt correction for that yet.

Truthfully it sounds like you have something loose, the Cusco parts will stiffen the ride but if you have something loose the vibration might not go away... re-spec the coilovers make sure everything is tight, if you still need the braces let me know

Are you running hubcentric rings on your wheels? If not, that could be your problem

true dat

If i remember correctly sohc already checked into hubcentric rings and like tripple checked the wheels and tires to make sure they were balanced correctly.

^yeah. I remember his thread from a while back

You still havent gotten this fixed? I thought you were going to honda?
