How fast has anyone gone w/ the s4 cab. I know there is more wind noise but I have had mine up to about 90-100 mph and it wasn't excessive, also handling still felt solid. Is there anyone who has taken a cab up to 140-150 and can share the experience. I'm in NY and if I get caught at that speed I'm going to jail. Cannot take that chance so maybe a can live vicariously through your experiences.
