Has anyone managed to get a Scalextric VW Beetle (C3361, C3484, C3642, etc, etc) to run mag-free?

I've tried all sorts with mine, short of a 3dp chassis......
Loads of weight, anywhere it will fit - including low down in the interior.
PSR 16k motor.
Scaleauto guide.
Paul Gage tyres.

......... and still it rolls out of the slot on just about every corner.

Unless anyone has any other suggestions, I'm going to give-up on this one.
