I would recommend against attaching a pull-type slave to the motor mount bracket. I did mine that way originally, and the problem is that you will get a lot of chatter when engaging the clutch. As the clutch starts to engage, the drivetrain twists, causing the clutch to disengage slightly. Then the drivetrain untwists and the process repeats, resulting in an oscillation.

I had a shop weld a bracket on my (steel) bellhousing and attach a push-type slave made by CNC. It works great.

This is important. You want the bracket to bolt to the motor mount/block and not the frame. That will eliminate the chatter risk.

Hi Jay,thanks for the info.After looking and the operation of the slave that came on the car and it seems to me that it pulls,not pushes as Reg told me.The body of the slave is mounted to the bell housing through a holl on the flange and the shaft face backwards and pulls on the arm coming out of the bell.Am I wrong?Can I just upgrade to a better unit or do I need to re-engineer this thing. It is a tko500 with centerforce clutch and lakewood bell. Thanks for the help!

Default Wilwood slave?

Aloha,

What brand / type slave cyl. do you have?

The original Wilwood slave cyl on my BDR failed early on, it turned out that it was due to an assembly error. I replaced it and corrected the error. I also rerouted the hyd. line and installed a two layer heat shield (modified Thunder1 model)
I've had no problems since, just over 4K miles now.
