No offence taken, but you may want to sonic test the bars for safety reasons, if they are too thin they will not protect you in a rollover even if your running 12's.
The car ran 9's and is capable of it again hence the reason to redo the cage, safety for you and the guy next to you in the other lane should always be taken into consideration.
As for detuning a 9 sec car to run 10's, once it ran 9's it has to pass inspection unless the car is incapable of running 9's. (different motor with less hp etc.)
Great looking car!
