With different tire sizes fore and aft getting tires from the "same batch" or "date code" seems unlikely but match brand/tread.

Its only the rears that need to have exact same diameter. So only the two rear, obviously same size tires need to be from the same batch.
Of course, if non staggered, and intend to rotate, you'd wanna make sure fronts were from same batch as each other (but ok if different batch than rears), as eventually they will be rears.

"Batch code" gets week and year of production. As close as we're gonna get. My S2000 fronts and rears have matching codes side to side but the fronts and rears don't match. Not surprising as they're different sizes and shipped from different warehouses although the same brand, and model. Not sure if the matching codes were pure luck or if Tire Rack pays attention to this. They're coming up on 5 years old so new tires are due in the Spring.

Heyo.
Sorry about a bit of a necro, but I finally got new tires on the car, and I'm still having this issue, but it doesn't happen until higher speeds now.
The car used to feel unstable at 80+ mph, now it's fine up till around 105+, then it starts feeling really wobbly again. Brand new DWS 06 tires all around, in a square setup, same pressure on every tire.
What's my next move? My local suspension shop says they don't "see" anything wrong with the suspension setup, and I've had it aligned 2 times, and they say there's nothing really that looks off.
Should I be looking at springs or coil overs? Maybe sway bars? Any advice or recommendations?

Could you post your alignment numbers?

Another thing to mention is on a square wheel+tire setup is tramlining. With the bigger wheels in the front the car will follow grooves in the road more and it will pull you around a bit. Very noticeable with a 8.5" front or above.
I run zero front toe with 1/16th total toe in for the rear.
Camber -2F and -2.2R. With my square STR wheels + tires it does the same thing you mention even playing with pressure it still will do it 50ish mph and above.
With my staggered street setup it's perfect and no issues.

This car doesn't appreciate all season tires. Why didn't you go for summer tires?

Please slow down. You should never take a car to 105 mph on public roadways.
let alone one that doesn’t seem well sorted.
