Slow steering response?


Kirk

Recommended Posts

I had a drive of another members car today with freshly fitted shocks and springs and i noticed it had very nice and sharp turn in and steering response in comparison to mine. Ive always had an issue with minor steering inputs with mine. It feels very vague and slow to respond at low speeds and has always required me to give it a little more lock to put the nose where i want it. Now seeming as the car is currently in bits anyway i figure this would be a good time to try and address this issue but the question is where should i start? Suspension issues? geometry problems? or could it be the rack itself at fault perhaps?

Input will be much appreciated.

Toe-in setting on you current car would be a first point of call but I expect you have had that checked before.

Did you have a speedo convertor or delimiter fitted?

 

My money would be on a geometry issue (not forgetting that the car you drove recently may have a not so desirable one)

 

Edit - did the other car have an aftermarket steering wheel?

I set the geometry myself about 4 months ago and it was pretty bang on minus a few minutes difference on the front toe and camber. Ill post up the print out in the morning.

 

Funnily enough yes it did have an after market wheel on it but i didnt think this would of made that much of a difference when it comes to general steering feel? :shrug:

Thought you might have the Toe issue ruled out, so that's a good start :)

 

IME a smaller aftermarket wheel can have quite a dramatic effect on the "feel" of the steering, most of all in the turn in and turn out of sharper turns like roundabouts or when the back end gets loose, i.e. power slides seem to me a little easier to control with a smaller wheel. It'll be a little heavier (which you may not even notice right away), but can feel like it's turning in/out more directly than when using the (rather large) stock wheel. I'm not saying this is the reason, but it's worth a mention :)

I can see where your coming from for sure. To be honest i find the steering to light anyway although the facelift steering feel was a vast improvement. I wonder if it is actually down to the smaller wheel then. Either way it feels noticeably better.

Martin its a 350mm wheels with 95mm dish on my car, as far as i can remember its always had good turn in, but it is a hell of alot sharper with the KYB's /Tein's fitted, i will be getting the geo done before pod so will let you know if its just my settings or your car.
