the older chassis can and will do well in VTA and even GT classes. The issue Ive run into is Im pretty much out of spares with my TC3. And I really like it, so Im not sure I want to add more money into it. I put a lot of laps,money, and time into the car for years. And when AE released the TC5, well new ride. Still love VTA and my TC3, but new is new....and it went from there.

older chassis are great, if you have parts, and already have the older chassis.. but for most new guys a TC4 Club car or a TC7 will fit more into their future as it will allow more room to grow.

to insert a rule on years on a chassis would hurt the class. How many people run VTA with a TC3 or older chassis....Ive been to plenty(most) large VTA events and they are a few, but no way the majority.
