    Question: Think the OEM spoiler is enough to take care of the rear lift the s2000 has at speed? Hoping to fix the oversteer bias at 100mph, hoping to avoid getting a wing. Maybe I should rephrase... balance the aero so that it behaves at high speed like it does at low speed.

    Elaborate Answer: (agreeing with Emilio) - No the OEM spoiler is not enough. It doesn't do much..

    Without rear aero, you need to give up LowSpeed front grip for high speed stability with a big front bar. In order to compensate for the lack of LowSpeed front grip (due to a bigger front bar), you need to put a massive front tire on it to get some of that grip back, but you will be adding some front grip back and will still not have the aero stability of a rear wing.

    Doesn't adding a wider front tire undo the balance change you JUST made with the front bar?

    Yup, that's what I said:

    "Without rear aero, you need to give up LowSpeed front grip for high speed stability with a big front bar.

    -So again, the answer is: NO. Adding rear aero is the best way to fix a high speed aero loose car. It's difficult to band-aid it mechanically without compromising the handling elsewhere.
