There are a bunch well into the 9s and 8s. It's RWD, so you can fit a big tire back there, and the launch will acclimate the drivetrain layout with the chassis squat.

Here is a local one running int he 9s on stock transmission:

Yet another on the stock 5 speed, deep into the 9s:

Can Z32s do it too? Sure they can:

ALL those cars above are full chassis street cars.
