You are correct - long rear links.
This makes the car more stable on corner entry and steer more middle off. Both Ronald and Andrew like to get on the power VERY early and we were struggling(Andrew) to get enough steering(especially onto the straight). Keep in mind that the whole setup works together so don't just try it once and expect it to work better...well sometimes you get lucky, but you know what I mean.
As for droop, I have always used "above ride height" way of measuring because it is stupid easy, and all you need is a ride height gauge - not everyone has droop blocks so they may not be able to accurately copy a setup of mine...oh and you don't need to take your wheels off!
So, for those who do not know what "above ride height" is:
1. Measure your rideheight.
2. Lift the end of the car you are working with(front/rear) by the shock tower and stop just before the tires come off the ground.
3. Now, measure again.
4. The difference bwteen the two measurements is your droop.
Important: The actualy numbers are only needed for recording purposes and to share setup information. When I tune the car, I am working off my base setting and not adjusting to a specific number. If I feel we need more rear droop for example, I will just take the wrench and turn the screws a 1/2 turn. After doing this more than twice, I will then, and only then, put it on the droop blocks to ensure the droop is equal left/right.
Hope that helps!
