If you're running a 200-r4, skip the t-brake. The StageRight hydraulic brake doesn't work well and is very inconsistent on launch. I would recommend going with a 9" non-lock converter with a higher stall (3000-3300).
Why would I recommend that? The higher stall makes it easy to stage the car and spool up in time for a launch. You can do this on the footbrake with improved rear brake cylinder and an adjustable prop valve. Your 60' times will improve.
The car will be consistent and predictable. It will kill some of the driveability and you'll give up some MPG, but it will be fun to drive.
