I recently mounted "Billboards" on my Roadster. They look great, but have most of the "bad" traits mentioned in previous threads (darting, hunting, wandering, ect). I did a forum search, and while the importance of proper alignment was mentioned several times, no one specified what the alignment numbers should be. I have had my car aligned using the numbers supplied in my manual, but I'm having no luck thus far in getting good handling out of these tires. The higher the speed, the more excitement ( not in a good way). And forget smooth roads, I live in West Virginia.
If you have had success getting your Cobra to handle well with these tires, please post your alignment specs and advice. I have a Mustang II tubular front suspension and a Ford 9" rear with 4 link.
