Pretty serious piece right there! Crazy however how to get a supra consistent/reliably into the 6-7 sec territory you need to basically take everything drivetrain, subframe, suspension, and electronics out of the car.
You basically have supra sheet metal and motor left at the end of the day. Haters gun' hate ;) I get it though, when most of these drivetrain parts are discontinued or super expensive its hard to be a private
racer trying to be competitive.

Guys have been running 7s without this subframe for a long time. I think this will help them go even faster/quicker.

Although this looks great, i thing someone should invested their time in a custom ladder bar or 4 link setup. Something bolt on which will be definitely a game changer.
