Steering dead on center

My S2000 has a small dead spot on center. It may have been just in comparison to other cars I had driven, but I believe the first S I test-drove did not have that dead spot. My steering otherwise feels tight.

From forum perusal, it seems like there are a few possible root causes here:

Meh tires (Firehawk all-seasons)

Alignment

Worn bushings

From the driver’s seat everything seems good with the alignment, so I’m leaning toward the tires to explain this. I got the car about 3k miles ago with new tires, so I’m not exactly rushing out to drop the money on new ones.

Anyone have success stories with eliminating dead spots?

Update: alignment scheduled for tomorrow, so we’ll see how that affects things.

I’m guessing steering shaft bushings.

I was gonna say “Well, it is a Honda after all!” but I’d rather be helpful — almost all of my weird on-center issues have been alignment related. Maybe the car has a zero-toe alignment or something that can cause vagueness in the middle of the range. Not necessarily a bad thing, just personal preference (especially if the last owner tracked the car).

Steering tie rods? Our MG F was vague in the middle and that was due to dead tie rods mucking with alignment...

My bet is bushings or the slip joint in the steering rack is just barely tweaked - like from a pothole or something. Your all-seasons aren’t helping the cause either.

Could also be steer-by wire. It seems like they all have a dead spot at TDC. If you feel a lag or shift on input, I’d guess tie rods, ball joints, or bushings.

Crappy tires will do it, but you might also want to look into steering rack bushings

Another possibility is suspension bushings causing some slop.

Oh, I'd really lean towards alignment. I've had bizzare self-centering and on center issues and it normally came back to the PO getting an alignment from a shop that just used generic specs rather than model specific specs. With something like an S2000 there's probably tons of tables of alignment specs floating around for different use cases...I'd pick one of those and take it to a shop to have it done regardless of if I had an issue just so I'd know what baseline condition I was in.

Baseline, that’s a good point. For the AP1 there’s a Honda UK spec that a lot of people like; I was thinking of trying that.

My vote is for worn bushings. What year is your car? Even with low mileage, modern rubber bushings go to shit after 8-10 years unless they’re always kept at an ideal humidity and temperature. They’ll lose some elasticity and the center hole will stretch out a tiny bit and you’ll get a little bit of play. Not really a big issue unless it’s bothering you or they’re completely disintegrated giving you metal on metal.
