Which one is stiffer, has better feel on hard turn in, and is more suitable for dry road course track?

Thanks!!!

(I have searched hours and am no longer interested in comparison of noise, treadwear, weight, price, wet performance, ... I am looking for the best steering response, feeling of the road, the z should talk to me on turn in and when going over slight bumps
I am NOT looking for a comfy, quiet ride with long lasting tires. Thats not what my Z is destined for . But it's still intended for daily driving. And I do admit that I really liked the oem tires with respect to the above and I really hated the 2 weeks driving on t1rs, sorry )

 

I never rode on So3's but one of my friends that races in the Nevada Silver State Classic, ditched his So3's this year and is going with the PS2's. Im more than pleased with the PS2's perf and long life. Just not pleased with their price, if they were 400 bucks cheaper on a set it would be an excellent buy.

 

i had so3,s and they do have a very crisp turn in and a harsh ride.but you do know whats happening,you can feel them just before they want to break away,which gave me confidence in knowing there limits.i liked them with the exception of following every friggen groove in the road surface.

 

I have PS 2's on NISMO 18's. I find that they have exceptioanl dry grip but break very suddenly with little warning...requires a very quick catch. I had stock Falkens on 17's before so can't compare to anything else meaningfully...

 

Honestly, it is a toss-up between these two tires. The top tier of performance tires all perform well and it is all a matter of personal preference. I have S03's and will be switching to PS2's for the simple reason that the PS2's will shave a whopping 22lbs of unsprung rotational weight off the car. (7lbs per rear tire-275/40/18 and 4lbs per front tire-245/40/18). This makes a huge difference. My vote goes to the PS2's for this reason alone. S03's grip well but are rocks.

 

Thanks for all the answers!!

I guess I'll try the PS2s and report back...
