We all knew the cars were different when we started in SM. When I got my first SM I had to make a decision on what year. So did everyone else. If you aren't happy with your choice, get a different car. At that point you're splitting hairs and clearly we're all talking about top prep cars, correct?
Why should we be changing rules to allow hybrid cars? If we did allow NB suspension on NA cars, I would expect some type of weight penalty for the NA's to account for the perceived improvement. So what would we have ultimately achieved in regards to cost savings, safety, or improved parity?
If it's not broke, there's no reason to fix it (can't wait for the first person to use that against me out of context).
