Apart from dropping the rear oil to 27.5w, 1.7mm piston and going from a White to Green rear spring, the car should be pretty drivable on kit setup on grass.
Take everything back to kit apart from the above (including connecting the silver rear rollbar). Make sure you don't make the common mistake of over-tightening the two small screws that hold the rollbar onto the gearbox case, it should float freely if you try and move it around when the car is sat at ride height. 99% of the 44's people ask me to go over at meetings have those two screws cranked right down, which can make the car do funny things.
Set the front diff pretty tight and start chopping spikes off the front tyres until you're close on balance. Don't be shy cutting rows off the front, even if you end up with 3 rows left or something it's the tyres that will get you most of the way to the balance you want. Moving onto springs and camberlink positions is just the last bit of fine tuning you do, if you're miles out on tyres no amount of car setup will help
