Price $159 + $10 express post Australia wide. Pics to come!
Here's the spiel
----------------
Our solid aluminum subframe bushings completely replace the stock bushings to eliminate free play of the subframe relative to the chassis. Solid subframe bushings will transmit more drivetrain noise to the cabin, but will greatly reduce wheel hop and improve suspension performance. And in the long run, rubber or urethane bushings will always need replacement, these aluminum bushings will last the life of your car.

Stock bushings have to be pressed/cut out from the subframe to install these aluminum bushings.

Construction:CNC machined aluminum

 

another thing to add to the list, I'm interested.

 

These are the ABSOLUTE best mod....

...you will ever make to a high-powered Z.
When Sport Compact fitted solid delrium Nismo bushes to project Z the handling difference was astounding!
Not so much for low HP or stock Z but big power Z's a must have.
End spiel.
