Even the best of my newly acquired GT3 cars have a tendency to “dance” or chatter on acceleration out of corners. chrisguyw has been a big advocate of bracing the axle holder uprights on SW and AW cars, recommending the Slotting Plus combi bushing/brace or aiding a wire U brace. So, the Slotting Plus product is $10 and currently out of stock at my usual supplier. My chances of accurately bending wire so that it fits snug but not so tight it distorts the uprights are nil. So I looked around the workbench and came up with some 3/32” square brass tubing that even I could cut and file to fit. Secured in place with some IC2000 adhesive it works great. The chatter is significantly decreased.
   

If building a car from parts or for a Proxy, the Slotting Plus setup is worth tracking down. But for a quick, easy and cheap solution I am happy with this.
