Thanks.

See below.



The droop screws shouldn't be touching at ride height, but droop is very important.

It's important to get the static weight distribution of the car balanced left to right. I use corner scales for this, but I think the TC6.1 has holes in the center of the shock towers that you can put a string / pin / small hex wrench into. Lift up both ends, and see if it sags to one side. It doesn't necessarily have to be absolutely perfect, but it needs to be close.

Before you put the springs on, compare each pair in terms of length. Sometimes one spring is longer than the other. You'll have to compensate for that in the preload adjustment. You might want to mark the long one with a sharpie if they're way off.

Next, set the ride height. Back off the droop screws to make sure they aren't limited your ride height.

Optional: lift up the chassis to see how far it lifts before the tires come off the board. Adjust the droop screws to get it in the ballpark. Probably 1.5-2mm up travel in front and 2-3mm in the rear. You'll want more on asphalt then carpet, probably.

Next, get the droop spot on with the droop gauge. I mean absolutely perfect left to right.

Finally, use a hex driver under the rear of the chassis in the balance hole and lift the chassis slowly. Verify that both rear wheels lift off the board at the same time. If one wheel lifts first, that means you either got the left/right balance way off, or your front end is tweaked. Tighten the diagonally-opposite spring, and loosen the spring on the same side of the other end of the car. When both wheels lift at the same time, flip the car around and repeat while lifting the front end.

You can also place the car hanging off your setup board, with the edge of the setup board going across the center of your chassis. Push down on the end that's hanging off so the end that's over the board isn't touching. Slowly lift the end that's hanging off the board. Both wheels on the other end should touch down at the same time. If they don't, you screwed up the droop. Watch how the suspension compresses on the other end as you continue to add more weight, especially as the chassis lifts off the edge of the board. You'll be able to see one side compress faster than the other if the end over the board is tweaked. Tighten the spring that sinks faster, and loosen the other, and try again. When it looks good, flip the car around and repeat with the other end. This technique does NOT work well if you have battery tape under the chassis. However, the stock TC6.1 battery mounts don't have that problem.

After all that, re-check the ride height to make sure you didn't mess it up with the spring adjustments. Then re-do all the checks to make sure things still look good.

If you have more droop in general, the car will be less sensitive to tweak. But as you run less and less droop, the car will be much more sensitive to tweak.
