I used white Plastruct styrene tubing, but anything will do, even scrap sprue from old plastic model kits. The tubes are in compression and tension, with little twisting forces. A solid blob of Goop (rubbery, tough glue from the hardware store) across the top of the axle bearing holders, and on the motor, are all that is needed:
This fix reduced the rear axle hop, vibration, and even helps keep the guide in the slot under braking (the hop was that bad). Best lap time on my wood track dropped from 5.344 seconds to 4.951, a remarkable improvement for such a simple "tweak". And, the car is more predictable, and more fun to drive.

Hum, quite interesting...
We're now taking on a Ninco race series (the Lambo' trophy) and since I'm way too used to cars with motor pod, the constant "jump" of the Lambo is hitting hard at my nerves.
This seems a great idea, though I'm not sure our race organizers will allow this, cars must be as original as they come out of the box, only mech stuff is allowed to change.
Now, just a small question. I've noticed the Peugeot had the "V6 engine" removed, doesn't that also help improve laptimes? I've been amazed how a few miligrams off can do so much in overall laptimes...
No, the plastic motor panel had been removed before all testing (I just didn't like the way it looked). I am not sure what the real 406 has back there.
Off Topic,
Do you have any idea what motor is mounted in the car on the foto??
Greetz Gordini
It's the Spirit motor.
The motor in the photo is the Spirit S3X, which is original to the car. It was supplied without its wrapper. RPM is 20.5k at 12v, and around 25k at 14.8v.
And a heck of a motor, I must say...
