good to know from someone that has actually measured it. So on your MM setup, you are raising the rear block 2.5mm and also raising the rear bulkhead tower 1mm with the skid shim? So how much spacers are you using between the transcase and the chassis to equal out the height of the assembly?

Longer link = lower roll center (It will give you more traction overall but you will loose some steering)
Shorter link = Higher roll center (cars is more reactive and rotates better)
Roll center has big impact on how you want the buggy to react in certain section of the track. "You add some you loose some" when changing your roll center. Rule of thumb you want your front and rear roll center as close as possible to have a good balance car...

This causes two problems;
1) once it breaks grip it pivots out and that is the end of that (sometimes the diff out will save you but on mega grip surfaces you'll have the diff tighter for forward drive so probably not)
2) really slows down the cars ability to change direction as it has to come from so far over
For really high grip surfaces a longer link makes the car roll slower (but ultimately further) but the stability it provides allows you to do the other measures which give you the rotation without making the car feel uncontrolably pointy or edgy.
If you look at the shock setups used in Europe you will find oils in the 500cst/350cst range used front and rear with springs like X-gear orange front and X-gear Yellow rear .... it's a different game as the cars don't really slide.
Also as for taking rear roll induced steering away that can actually help on high grip tracks as it controls the weight transfer and thus helps keep the rear flatter through the corners encouraging more controlable rotation.
There was a reason that lengthening the rear link wasn't first on the list!
I won't run on (the only 2) clay tracks in the UK for the simple reason that you ideally want a completely different car, the two really aren't easily transferable IMHO.

I currently run 21g in the rear. Led weights drilled into and by it screwing it down while I envy 2 others who use custom made weights.... all into the newer swaybar rear hanger.

Adding weight in the rear in MM makes it easier to drive by settling the car down and also giving you a little more room for error.

Hey guys, been really working on my car in MM and weight distribution. I finally found something that is pretty easy to drive, but can turn on a dime if needed as well.
Our track is smooth right now, but can get bumpy, dusty and loose out of the groove.
Here's what I have done to the car to get the battery back as much as possible.
The only thing you need to do is modify the battery braces and shoe goo the RT6 part in place (it fits perfect) unless you want to drill 2 holes for it.
Also here is my current setup.
