    Are spring rates the same through all years?

    For 4-door 2.5 models. I think I might go back to the stock spring rate for a while, but I have a late model and most of the cars in the yards are early models. Same spring rate?

    Maybe not exact as I think it changed a touch with the I and IS models but nothing to worry about. All close enough.

          Saw that, but it doesn't make mention of differences in years.

          I guess the answer is to check part #s on realoem.com. Didn't think of that.

            Yes, they varied by year, model, and even options (like A/C). As stated, nothing that will make a noticeable difference. Most of them are out of spec by now anyway, from bouncing around for the past 20 years/200k miles.
