I wouldn't say no travel. My blue Dart is riding on the bump stop or pretty dang close and the car rides very well. Those bump stop are probably close to two inches thick and they do compress pretty easily. Just guessing but I would think two inches at the bump stop would probably equal about four inched upward travel out at the wheel and tire.
I don't think my blue Dart is really that low. Makes me wonder how much clearance other members run on their cars. Maybe a poll thread is in order to find out what other member run for clearance on their bump stops.
