I have the H&Rs with the Bilsteins and I am glad I went this route. The fitment is awesome. I also am running stock 225-50-16 at the moment. The tire sizes you run are a bit tall. They will rub with just about any lowering spring except maybe the HKS. I just bought some 18's and have yet to install them with tires so I dont know how much it will effect ride quality. Right now I think the ride is only remotely stiffer than my stock touring suspension and is vastly better as far as performance. I would recommend this set up to anyone. I live in NH now and the roads suck *** so I feel your pain.
