Handling feels less precise than before, suspension 100% original

Get a performance alignment done where the shop sets your four corners up for best handling, not just simply checking to see if things are within spec. Look up the UK specs and locate a reputable alignment shop that is familiar with S2000's then have them set the four corners to the spec you want. Have them give the entire suspension the once over for wear and tear, including wheel bearings.

I would check all four swaybar end links. If one is broken, that swaybar is effectively no longer part of the suspension. That would cause a very dramatic detriment to handling.

What was your last change?
What tires were on it previously?
How many miles on the car?

He has an AP2 and the UK spec is only for AP1. I highly advise against ever putting the UK spec on an AP2 as you lose stability at higher speed turns and will bite the dust.

I notice that when I run different tread patterns on front vs rear that the car does not behave the same.
I just had new control arms put on at 140k because the bushings were shot and that made a difference but not as much as having all 4 tires being the same tread with a proper alignment.

You state you have both PS2 and PS3 tires on the beast. I suspect that is part of the issue. This car is super sensitive to tires. Having newer, uniform tires might be the answer in addition to other comments on alignment.

Stick to model years, not engine or UK "plate numbers." AP1 and AP2 are engine designations, not chassis. Yeah, it appears in the VIN where "chassis code" normally appears.
2004 and later cars all have the same chassis/wheels/suspension/etc. UK/EU cars retain the AP1 engine. North American cars got the AP2 engine (Japan in 2005?).
In this case I'm betting on mismatched tires fore and aft. I always felt Michelins were a lower tier tire regarding handling.

I hated UK spec alignment here on US roads. Darty and edgy, so probably good for much slower speed tight roads in Europe. It’s really the toe out within that alignment that does that.
Anyways, my car felt sloppy and unstable at really high speeds and corners too. I go and replace motor mounts since they were long overdue but I never had any vibration... and both were torn.
The ride is much more compliant now and confidence is back. I’d check those too in addition to everything else others said. Oh and no toe out up front please if you want highway speeds confidence.
