SideShowBobDepends on the angle of the downslope, but try to make the flat as short as comfortable, and I usually make my lip 1 foot high max. Remember to keep speed make sure everything is smooth. Trial and error is really the only way to tell
Jib3rishAlright... And how high for the rail if the lip is a foot high? Thx
Jib3rishJust rough though... Like 3 ft or a foot.
