Link cars obviously work on asphalt as well as carpet, but it would seem to me that 't' bar cars are eaiser, faster to set up on asphalt.
As I found out the hard way when running a link car on asphalt (or any surface) make sure your starting out with new tires. Do NOT use tires that you may have had from last season. They just don't seem to work and you keep chasing a car that doesn't handle.
