In the way the program is now formatted, there is not room in each entry for another line of type with that information if the entrant fills in all the lines provided for owners, drivers, crew chiefs, crew and sponsors. If you review the format, you'll see that the class record and record-holder is listed with the first entry in each class. And putting less entries on a page is not a financial option in expanding the program.
Most racers will give you their personal contact information if they feel like it. And this forum serves to find out about those that you may discover you want later or have lost info on.
