Tried to file it flat but could not get it perfect. So I just run those screws a quarter turn loose so they will not introduce tweak into the chassis. Also, the turnbuckle that bridges the gap between the top deck and rear end was too short actually causing the rear of the chassis to curve up.
Once I got those two problems sorted out the car is so much better to drive.
That chassis link is a pain. I snapped mine on then adjusted it until it rolled free side to side. It was way too tight using the kit suggested gap. Just like a link rear end on a pan car, if its not free its tweaking something. And this link really does affect chassis flex so it needs to be free and smooth.
