lol i wasnt expecting such extreme replies re tire pressures.
i also was when i was them 15 psi...
but even yesterday i talked to him again, and he said that he had experimented with a lot of different pressures, and for the local roads he is positive that 15 psi is the best.
i do not agree, i had put them to 30 the first time i realised. i did not drive it hard at 30 so cannot say if it was better, it was HARDER thats for sure. with 24 psi it has a very comfortable ride...

i will experiment this week, will try to put them up to 32 to see what happens. but i am afraid it will have too much oversteer...

Regarding the swaybar, did not have time to check today (was hung over as hell), but where can i check from? Should i remove the rear wheels and check from there? I'm very new to the s2000 so dont know if there is anything special ..?

thanks a lot for the replies tho ... i appreciate your help.

Some people at the track run around 28 in the front, 30 in the rear... but that's more for track use. Using that low psi on the street is dangerous to yourself, and people around you.

of course it feels softer, your tires aren't inflated the way they should be, and your sidewall is flimsy. I would be surprised if driving around @ 15 has done considerable harm to the sidewall

Check your suspenion make sure the rear sway bar and links are in tact

The tire sizes you have will induce some understeer but isn't the main cause of your extreme understeer issue.

I normally run 36 psi all around.

If you are looking for a soft comfortable ride this is not the car for you. You should be looking for more of a cruiser like tl, g35, something along those lines. The suspension in these cars even the refined ap2 is a bumpy ride.

The previous owner is a moron! Do not listen to a single thing the guy says after he said that...

Wow. I was actually worrying that my pressures were at 31.5 psi at last check. I couldn't imagine the handling with 24, or wow... 15??

Do you remember hearing about people getting killed in Ford Exploders, even they were running pressures higher than 15 psi.

Try something like 34 in front and 32 in the rear. That would limit some of the oversteer. And no, that's not too high. That's a bit lower than what I usually run. Once you get into normal psi range (30-40) you'll get an idea of how the car is supposed to drive. Then you can play with the ratio front and rear and find what you like. 15psi is not only ridiculous, but dangerous as well.

Someone mentioned some track guys run as low as 28 psi. That seems really low to me too. Maybe 28psi cold - which ends up being about 34 psi once your tires are warmed up and you won't get too high (~40 psi) by the end of a long session.

As for sway bars, you'll probably have to remove the rear wheels. You'll see the endlinks connecting the bar and the rear suspension. Make sure that's connected and not broken.
