Im nearly finished building my youngster frame, I shortened and widened it a bit. I flipped the front spring perch and will mount the front spring over it instead of under. I want to use a spring over axle as i dont like the look of the front wheels way out in front of the radiator. I want it low but not slammed. planning to order kit with axle, hairpins, spring, etc, from speedway. question is 4" or 6" drop? I have no reference on how tall the spring is. In my case the bottom of the center of the spring will sit about center of the front frame tube. Thanks
