for all the racers out there what droop measurements is everyone running and is everyone checking from shock bolt to shock bolt?
trying to find a good indoor set up tight and technical most run super soft wishbones and soft wishbones

But this seems to say finding ride height at 4 points on each arm.

Yes, I would like to also know where you check ride height - I thought it was to the bottom of the chassis. For the front I measured behind the kickup portion in the middle, and in rear at the middle.

I measure droop from shock bolt to shock bolt as per the manual, page 32 I believe. I undo the top end of the shock and measure from top bolt to the bottom bolt(still attached). When it is set up right the top of the shock then slides on perfectly - that is using the recommended lengths.

Whoops, see that you said Droop, not ride height.

Can you elaborate on rebuilding diffs? Is it replacing all o-rings and gaskets, draining and refilling the oil, or is it just replacing the oil leaving the gaskets and o-rings for when they start leaking?
And if it isn't leaking, does the oil wear out that quickly? Wondering why this is needed so frequently.
Thanks

Viscosity of oil changes with all the heat generated there. If your car does not leak oil, do you blow off the oil changes?

the oil also gets black and dirty. Just a good idea to keep the sandpaper like oil outta there.

Todd, I am running same motor as you. I use 17 or 18 pinion. So 16 to 18 is good, depends on track straights length. If most are short then 16 is all you need. Chk your motor temps. Try to keep it below 160. Most people here use Tekin so their gearing is a going to be different.
And I left ESC settings at default.

Measure the the C-hubs - you mean the castor blocks? Not following you here, but then I am neck deep in reporting our weekly backups for my boss.

RE DROOP: This is a huge adjustment and you would be amazed at how many really fast guys dont even know if they have more droop on the front or the rear of their cars.
I have never used the 'Shock Length' method because if you change the way the shock is mounted it is going to change the droop.
I take the wheels off my car and set 2 of them on a flat surface and place the buggy on top of the wheels and measure the distance between the 'ground' and the bottom of the threads of the wheel hex head.
I have found 29mm front / 29mm rear makes for a nice neutral car. More rear droop vs front (30 front / 28 rear) is great for tight tracks with a lot of slow 180s.
Less rear droop vs front (28mm front / 30mm rear) takes away some steering and can make the car push and then snap oversteer.
If you use this method you can change shock mounting locations and maintain droop setting you prefer.

They show a caliper to measure the distance - I suppose you need to estimate where the center of the bolts are, leading to error. You could just measure each bolt, divide by 2 and add both values to the inside to inside measurement. A bit of a PITA, but should provide better measurements -no?

Yes, c-hub or castor block. You mount the buggy on 30mm setup blocks on a setup board and then measure from the base of the setup board to the bottom of the block. This is how it's down on on-road touring cars. In fact, you do it with the shocks off, so the shocks mean nothing.
Seriously, that is good info - I'll try that tonight. So then the numbers given by AE in the manual are useless if you change measurement method, right?
