Default Crazy bumpsteer in '91 CRX Si--anyone have a fix/same problem?

It's lowered with Neuspeed Race springs front and rear on Tokico Blue shocks. After the drop, I got a four-wheel allingment (just a standard one at the local repair shop). The only other thing I have done to the suspension are 16" wheels with 205/40-16s. Oh, and the bumpstops weren't cut, but the Tokicos came with shorties and I used those.

The ride is super harsh and jolty, and the car jets sideways unexpectedly on many bumps--especially when only one half of the car hits a particular bump. I would think that even though that's not a lot of mods, it should ride considerably better.

Does anyone else have this problem? How is it fixed? I think I heard of a fix by raising the steering rack--has anyone done this? Please help 'cause it sucks.

I have Neuspeed Race springs front and rear on KYBs and its a little stiff on the backroads but rides nice in the freeway. I think your problem is with the cheap *** tokico struts. I have heard alot of bad things about them

Oh, and the spring rates for the Neuspeeds are for a '92-'95 Civic Si Hatch.

I have tokico blues on neuspeeds sports (I think the same spring rate as the race but just less of a drop?).. Anyway, the shocks are nowhere stiff enough for these springs. I also blew up one of the shock within a year and trying to get ahold of tokico is like trying to pry the honesty out of a politcian.

If I had to do it again I would get stiffer shocks... I'm still considering it actually.

But does your car randomly steer itself without any steering-wheel input?

Maybe I should add a little caster in the front to keep it tracking straighter.

I had that same problem. It was the most scary car I have ever driven. I just lowered a crx and installed integra shocks in the rear without looking at the height. The car was riding on the bumpstops and wasn't even touching the spring. I don't know how low your car is, but you might want to look into it.

Your car is going to ride a tad stiffer since the spring rates are for a heavier car than your crx.

I have gsr springs, but my car weighs in at about 2200lbs the ride is stiff, but its not bad, id point the fingers at your shocks, that or your toe is way out .

1) Wrong wheel offset?
2) Excessive front toe-in or toe-out
3) Uneven front castor setting
4) Uneven shock forces
5) Front anti-roll bar way too stiff

Not sure. I ordered them for a '92 EG. (I had them on one before I wrecked it).

Just seems strange since I got an allignment right after lowering it.

Same response as before, however could it be from simply not enough caster? If it were uneven, wouldn't it pull always to one side? It steers both ways.

I installed them myself, and I know I put the correct ones on all corners. This could only be from if they made a mistake at the factory.

It's stock.

Thanks for your ideas so far, everyone. Please keep 'em comming--we're bound to hit the nail on the head. Driving this thing is too much like work!

It's not slammed by any means. There are at least two-fingers in the rear and a little more in the front (from the tire to the wheel well).

I doubt ur problem is with the tokicos as some are saying. i have had nothing but good results using tokico shocks. Check steering rack bushings and tightness maybe?

I had to get mine aligned twice before it was done right. I had similar problems. A good alignment shop should be able to take care of it. The second shop I brought it to listened to my problem, drove the car, and gave me back something completely better.

That could very well be my problem. I took it to a shop I used to work at and they did it for a case of beer (I gave it to them after the work was done). I'm sure they just did a poor job at it.

This next spring, I'm going to try a set of 15s instead of 16s because I'll need new tires anyway. I'll get an allignment at a REAL allignment shop this time and hope for the best.

Thanks.

I had Tokico Blues w/Goldline springs on my '91 Si a few years back.

Then I got an Ingalls camber kit (which got the camber perfect all around) but it had very bad bumpsteer.

It was done at a respected shop, and I didn't bother trying to get it done again.

I just assumed when you get the camber kit one of the side effects was bumpsteer. I didn't know much back then, though.

So, did you ever get the problem fixed? If so, how did you do it?

All right this is from experience.

I had huge bump and torque steer on my CRX. Every time I smash the gas the car would go all over the road. Couldn't figure it out till one day H-T member (Alex) asked me if I indexed my bushings.
I was like WTF that makes a difference??

Anyways, I took the wheels off and jacked the car up and dropped it on the LCAs so I can index the bushings(also called loading your suspension). Loosen all the LCA, UCA, & all those bolts that were mounted to the LCA.

Checked to make sure the car was at it's driving height then I tighten all the bolts up. Ever since this I had had no torque steer, bump steer or what ever steering problems.

I was amazed at what something like this that I had overlooked for so long could be the culprit.

Do this and it should fix your problem, then again.

If your car has being in a accident then that's another story.

my CRX does the same thing... i have tokico 5 way coilovers. my friend always "borrows" the CRX because he says its fun to drive and every time he drives it he says it is terrifying because of it's behavior. i'm able to predict its movements so i don't notice it but apparently it must be real bad.

i just recently bought some tokico 5 way adjustables, eibach springs, and Energy's polyurethane bushings to replace the old stuff. it's just a matter of taking the time to put that stuff in now...

Try it out man, it could solve your problem.

I still have stock shocks in my car so I know it ain't the shocks nor the H&R springs that I have.

But seriously the car feels like a new animal and I love my rust bucket even more then before.

I have minimal bump steer..but i get a lot of "pull" when I'm on one of those crappy black top roads that have ruts in them from heavy trucks.

I'm going to try "indexing" my bushings this week and see how it does. Just from reading this and putting a little bit of thought into the idea, it seems as though it should work really well.
