The smoother the track and better the traction, the stiffer the center shock can be.

Soft center shock = more rear traction and more low speed steering. Better in the bumpy sections.

Firmer center shock means more high speed steering and more ON power steering.

There is a balance point that you have to find. I almost always use 30 wt in the center shock, although many will argue with me. I have seen posts of people using as high as 60.

I find setting the droop so the rear pod just hangs down 1 mm to 1.5 mm and letting the car just settle into its suspension no matter how stiff the center spring is, makes the car drive the easiest and most consistant. This leaves the chasis levil under laoded conditions with out the body on.

I also think stiff spring with heavy oil defeats the purpose. I want the car to react fast to what is happening with lighter (30) oil.

Hope I helped

ONLY MY opinion. I only run STOCK.
