With lighter to heavier lube in damper, this does what effect?

Center spirng and Oil weight , what happen with light to heavy?
Please let me know what the duties are for these and what would you recommend to start out with. Thanks for the help and time.
I'm not too familiar with link cars, but the basic concepts should be the same as T-plate cars. Not an expert, but this is what I have found:
Here is a good link for setup suggestions:
Lighter or heavier side springs should be like running a lighter or heavier t-plate. Lighter side springs should give better rear traction. Heavier springs can be used to free up the rear end and perhaps make the car react faster.
A softer rear center spring can make the car have more on power understeer. It will give the car more rear traction and make the car easier to drive. It will give the car more "throttle" steering control. The rear will squat more on power and it will push under power.
Not too sure what center dampening will do, I generally run as little as possible, perhaps 30wt to 40wt. Just enough so that the car doesn't bounce on a rough track.
Mike's web page gives some good information on side dampening:
Damping Very little damping is used initially when I start at a track. Add damping to the rear end to add more steering. I have tried many types of grease, including various oils and diff lubes (the type of diff lube is not important, I use and try many types on the discs). The tension on the damping discs should be very light in most cases (cut the spring to reduce tension if necessary). Remove damping fluid to obtain more rear traction. If a lot of damping is used then a thin T-bar may handle better in extreme situations, but I do not typically like this setup.
I find that if you use too much dampening it acts much like a heavy T-plate or heavy side springs, it takes away rear traction. I would think that lighter dampening would make the car react faster.
Again, I am not an expert, so don't flame me if I've made some mistakes here. But this is what I have found from my testing.
