Closing the argument on b4.2...
-New box will have cav's car on it (not much different from the old box)
-Same chassis
-Big bores
-Hexes
-VTS Slipper
-Aluminium steering rack
-Possibley new shock towers
As for the t4.2 and the sc10.2 i believe they'll be getting the new Short Course Buggy front arms as well as the stuff listed above. There is a 90% chance that announcements for the new kit will be made around late Jan or early Feb after Reedy Race and I would assume the new kits will appear on shelves late Feb early March. Unless Associated decides to do something weird I'm pretty sure this is how things are going down.
