The series is going back to the Phoenix oval track this weekend for the first time in years. Roger Penske voiced some concerns over the "crazy" amount of downforce in the short oval package (over 6000 lbs. I believe.) He mentioned Montoya's suspension failure last season and seems to have some concerns. I do know they tested around 190 m.p.h. which is pretty fast for a short oval. Hopefully it will be a competitive and safe race.
