I agree with most that age does not matter. We have an 05 coil over micro sprint and in our area most have 2010 and newer four bar micros. I was told my car will never be competitive yet we are very competitive. We have also run older midget chassis with success.

The key is knowing your car and what it needs setup wise. The two critical things we have always made sure we had in top condition were bars/springs and shocks.

A chassis does not know its age. A chassis only knows what you are telling it to do through your driving and setup.

Maintenance and knowledge of your car will always be your best combo for success.
