I understand the difference in terms, downstops are adjusted with the downstops, How is the droop adjusted?
In fact adjusting the downstops is the same as adjusting the droop. Here a step by step way to adjust your downstops/droop:
1. Check and adjust your right height (left and right, not in the center). Than detach shocks and anti-roll bar. Remove the wheels
2. Tap on the top of the upright/c-hub. This is to make sure the suspension is in it's lowest position.
3. Use the droop gauge to see how much mm the arm is above the chassis. I personally recommend the Hudy droop gauge set, because it works a lot easier when you can just put the car on the support blocks.
4. The number of mm's is the downstop value. This is what most people mean when talking about their droop. Measure this very carefully, just half a millimeter can make a world of difference.
5. By turning the screw in (clock wise) you will increase your downstop value. By turning the screw out (counter clock wise) you will decrease your downstop value. Change your downstop value to the desired amount.
6.When done check if the left and right are the exact same value.
7. Re-attach your shocks, rollbars and wheels. Use a screw driver or anything similar and make a lever with the edge of the table. Put the end of the screwdriver in a tiny hole almost completely in front (or rear) most cars have such a hole. If not, use a small string and put it around the center of your shocktower, than you can lift it from there.
8. Slighty lift the car, and check if the wheels come loose at the same time. When they do, you're done. When they don't, it's up to step 9.
9. Slightly turn the ring on your shock (the one you normally use for your ride height). make sure left and right are equal. After this check your ride height and downstops again. When ride height, downstop value, droop and the height of the rings can't be all set equal left to right. You've got yourself a problem, it means that either:
- Your car is completely unbalanced left to right (weight distribution)
- Your car is tweaked (so check the car for tweak and your chassis whether it's bent or not)
- You're just not good at this
Extra reminder for people using foam tires. Because foam tires get smaller after every run, you should check your downstops,droop and ride height after every heat.
Why is droop so important? It's the amount of travel your chassis has before you're wheels lift from the ground.
This is (a summary) of what droop does to the car:
More droop front (lower downstop value):
- When going on throttle the car can travel upward more.
- Less steering on high speed
- Better for bumpy tracks
Less droop front (higher downstop value):
- When going on throttle the car can travel upward less.
- More steering on high speed
- Better on smooth tracks
More droop rear (lower downstop value):
- When braking or off-throttle the car has more upward travel.
- More steering in slow corners
- Better on bumpy tracks
Less droop rear (higher downstop value):
- When braking or off-throttle the car has less upward travel.
- Less steering in slow corners
- Better on smooth tracks
When you want more information on it has that effect on the car. Just ask and I'll explain. But it's too long of a story to be writing down when nobody is interested
