It's a pretty well documented issue with the turnbuckles rubbing the chassis on full drop. One thing that I and others have done is cut down the chassis and suspension block area where it rubs. A file or dremel with a milling bit works great.

First, and not surprisingly, there were no droop screws included, but I was able to use some screws from other kits that did the job.

The reason I needed those droop screws was twofold. The springs themselves were waaay too short for how tall the shocks were supposed to be built. Even with the manual suggested spacers installed, there was a good five millimeters of travel in the shocks beyond the length of the springs. And when the shocks were fully extended on the car, the turnbuckles would catch on the chassis as the wheels turned. This contact would limit steering throw to only about a third of the maximum. If the turnbuckles caught on the chassis from the servo moving the steering, I would expect disastrous results.

Using droop screws to keep the shocks short enough to keep tension on the springs and to stop the turnbuckles from jamming on the chassis, the car still has a maximum ride height of 21mm, fully extended. I still don't have any electronics installed, so I haven't been able to set its resting ride height yet. Anybody else have these problems?
