Converter. Trans brake questions.

I wouldn't get a transbrake for a couple trips to the track. There's guys running way faster than you ever will off a foot brake. The key to running fast is consistency. Adding a transbrake only adds another variable with no real benefit. The way you stage, tire pressure, suspension set up is all different.

The one thing that is always worth spending money on is a top notch converter. A quality converter will basically drive like a stock one until you really hammer it. It takes a certain amount of torque/hp to overcome the coupling effect. The highest stall converter I've ever driven was a 5500 stall speed. You could drive it like a normal car. I've also driven cheap 2500-3000 converters that felt like a bungee cord, and would cook the fluid.
