A T/S and P/S chassis is a close comparison. The 2x3 7.50 cert car is not. There is more requirements for bars and frame rails in the T/S and P/S cas versus a 7.50 cert car. If money was not an object, I certainly would look at a P/S car. You can make the necessary adjustments to make it a low 8 second bracket car. Probably a little over kill with some of the equipment but it leaves you room to move on. You will find a quality T/S car for less money and it will work just as well.
Overall, if you want to go fast for cheap, buy a dragster. :lol:
