not the 2 seater the regular car. The one they ran in Indy this yearThat would make sense since there is another 4/5 foot section in the car that added probably 300/400 lbs with the extra Rider in the car. Also this car would never be able to be tuned to actually race. It probably has a bunch more bracing in it too. This is apples and oranges and not related to needing a spec change for competition.
