This is where mine was.Took about 2 hours to find the problem and fix it.
The real problem is the multi-flex cutouts under the bulkheads.When on high bite tracks and the chassis flexes,this forces the bulkheads to shift slightly in any direction.Every time you turn your car ,the bulkheads shift again.. in another direction.. causing an inconsistant car.
This of course,is MUCH worse if you hit the wall or another car.
The chassis dictates everything,including shock tower placement.If the right side bulkheads move more than the left side this will cause the shock towers to move,causing tweak...again.
The ONLY way to help this from happening is to replace the chassis....with one without cutouts in it OR.....
After EVERY run,relax all the screws attached to the bulkheads(including the ones under the chassis,shock towers,topdeck and standoffs...everything),twist the car slightly back and forth,place the car on a flat surface and tighten everything back up.
Solid chassis=NO bulkhead movement=no tweak=consistant car.(unless you hit something hard enough)
