Some pictures of the option parts installed.
I've installed the disc-damper on my Murcielago, and installed aluminum parts on the Countach.
Next upgrades will be complete package for the Porsche, and ball bearings, springs, and H-plates for the Countach. I might add a gyro on the Porsche, but not the Countach.

Only downside of the disc-damper is it does not fit directly under some bodies. Had to drill a hole in the Murcielago for the top post of the damper.
The Murcielago is now rock solid full on racer! Just wish I had a track to race on!

Hole should be a little bigger to allow more movement of the system.
