I am interested in getting a JL WU, mainly because it is the only SUV out there still with a Manual transmission. However, I do a lot of highway driving and all the reviews I have seen give poor reviews for highway travel. Is there a specific model and/or aftermarket suspension I should look into to make it better on the highway? I know tires make a big difference too, so I would have two sets, one for day to day and one for off road. Thanks!
