I agree!
that's the most likely!

Are you sure all 4 tires and rims (which you changed) are in perfect condition?

 

I really need someone local who specializes in S2Ks, but I don't think there are any.

It's impossible to express the problem without experiencing it.

 

what about your local Honda dealer?
or did you consult them already?

 

My bet is they'll take my $100 and tell me I shouldn't have lowered the car.

But.. since I'm getting desperate, I might go there next.

 

You might want to seriously consider reinstalling the OEM springs and taking the car to a reputable Honda dealership.

 

Actually I have considered that.. but it'd be a $600 round trip assuming I have the lowered suspension re-insalled at some point. And that doesn't count the cost to actually fix whatever the problem is.

 

Ouch! But Matt, what are the other options? You need to have someone that can diagnose this kind of problem take the car for a drive. If Billman and the other S2kI resident S2000 specialists can't come up with any suggestions and you can't find a good mechanic through your regional forum, then you're pretty much stuck. A new diff will cost more than $600, and that might not fix the problem either. You've already thought of everything I can think of, and it may just be time to make some hard choices. Know what I mean?

 

Oh, yeah, I know what you mean. I'm still in the mode of trying to think of cheaper stabs at the problem, though... Hence the half shaft spacer theory.

 

Too many pages to read so im not sure if im reposting. apologies if i am.

I bought my s2k almost a month now, went from an itr to s2k.

I had some vibration issues under load after i lowered the car. I can say im quite a noob to the s2 and after researching and suggestions from muiltiple shops, the vibrations were caused by the driveshaft or the diff but no one was certain.

The vibration comes from accelerating under a heavier load. You can feel the whole car vibrate and shake to the point u dont want to accelerate.

Under no accel, the car wont vibrate at all.

I was prepped to purchasing new driveshafts and possible the whole rear end just to be safe BUT......

I decided to try out the halfshaft spacers first. Mainly here on s2ki, ive read many of you say these are quite useless and a waste of money.

After research, i only saw one clear post of a member here that simple said "i had vibrations while driving but after installed spacers, vibration went away."

So i thought a hundred-ish bucks for the spacers, might as well try em out, better that over a grand for new shafts and diff etc.

Install was super easy, took less than 30 mins to install and torqued to spec thanks to my awesome mechanic.

After install, vibrations were all gone, car is smooth as a babies ass.

The spacers were developed for a reason, logically, every lil bit would help the car and the life span of the driveshaft. This piece isn't very expensive either. Whether it can cure your vibration problems like mine, or simply an add on to your mods, i think its very worth installing.

Conclusion, heavy load after lowered car caused major vibrations to the car, halfshaft spacers have cured that problem thus i'm more than happy

Again sorry if i reposted this conclusion, 8 pages was just very long to read

(Halfshaft spacers: T1R Forged)

matthouston23:

I just read some recent posts of yours on this thread.

Im guessing you're going through what i went through as well.

I didnt know if it started vibrating the day i lowered the car or not either, and steps you took was the same as the ones i took.

You went further than me and replaced your halfshafts but from quickly reading your posts, i believe your vibrations still exist.

Then mechanics went to say it may be the diff, same with those who tried to analyze my car as well.

Try out the halfshaft spacers. It may cure your problem since it cured my virbations instantly.

Im running skunk2 race springs for the winter, rear is slammed, well not crazily low but pretty low.

I installed T1R forged spacers and i havent had vibrations ever since. Its smooth as oem no matter how heavy load you put etc.

Hope this helps. I dont think its guranteed to cure vibrations but it definetly did for me, so its a route you can try out.

Cheers.
