The competition-spec roll cage was fabriated by MD Custom Automotive, Inc. Their website is http://mdracecars.com/ The cage is DOM steel tube with NASCAR type side bars. Thanks to Marty Danko for a superb job! I'd like to thank the fine folks at JD's Auto Repair & Performance Center in Huntingdon Valley, PA for all of their help. Reach them at 215.938.9270. Their website is www.jds-high-performance.com And it goes without saying that I give thanks to my Father (the 2008 Rookie of the Year!) for all of his hard work, technical skill, engineering wisdom and everything else. This project would be nothing without him!
