NT01 PSI recommendation
 
[left][left]
How does the wear look like? What PSI os recommended for S2000? I been running ~32 hot psi.

I have had 6x sessions at VIR and 8x sessions at Carolina Motorsports Park on these.

12/10 kg ohlins ots
-3 camber all around
1/16 toe-out front and 3/16 toe-in rear
3070 lbs wet with driver
255/40/17 squares on 17x19.5 wheels

Ignore the yellow markings on the tires. The markings were there beefore last rotation.

They look ok. Tons of life. Be sure to rotate. I used to run them around 34-36psi if I remember correctly.

Look good to me, wearing even across the whole section width.

Out of curiosity, what width wheel and tire are these?

I was running very close to the same setup. Same spring rates on KWs, stiffer front bar, no rear bar, AP2. 0 toe in the front, 1/16" total in the rear. Camber was ~ -2.8 all around. To me, it looks like you're getting a smidge more inside tire wear on the fronts. 0 toe would reduce that. On the rears, it looks like a bit more of tire wear on both edges, so maybe need a bit more tire pressure to get more wear in the middle of the tires. But that's really just eyeballing from photos.

I've been running 38-ish hot but I seem to be having significantly quicker wear than you show there. I predict they will last me about 8hr.

Rears look fine. Fronts are taking too much inside wear. I suspect its your toe setting since that 1/16 out becomes 1/8 when rolling with deflection. I usually run 0 to 1/32 in front toe in with poly bushings (less deflection).

I run them at 34 hot.

Agreed, I also run 34 hot, seems like anything under that and I'll burn take the edges off the tires within a couple sessions.

Thanks for the comments. Ran them at ~34 psi hot and felt good.

I tried out 34psi hot yesterday, they seemed to work really well, but these things melt like butter.
