If the effect you are trying to minimize is the tendency to push you "off line" so that you have to correct the steering.......there probably ain't much you can do about that, if anything.

Now.....with your mileage, some suspension work is likely needed starting with shocks but you can spend a TON of money and not really fix the problem of a high profile vehicle being pushed around in the wind.
