If you mean the springs for the damper plates...you dont do anything to them. To adjust sis to side damping you use vaious types of silicone goo. Diff lube is great for asphalt. Keep in mind that you need a lot less damping than you might think you need....even on carpet.
The setup I use for pan cars is to have the bottom pod plate slightly drooping. Not on the same plane as the chassis. This is done because when the car accelerates, the pinion gear wants to climb the spur gear a common event on gear driven cars. (Thatís why you see drag cars pulling the front wheels off the ground or top fuel cars bowing the chassis in the lights) If there is not some adjustment to allow for this to happen, then you can unload the front wheels causing the car to dart because the caster changes on the front suspension. You can achieve the rear pod droop by one of two ways. You can lengthen the overall length of the shock or you can put a shim(s) between the front pivot ball on the T bar and the chassis plate. Which ever method you use, when the car is setting on the ground, the motor pod and the chassis plate should be on the same plane. To make that happen, turn the spring adjustment on the shock down until the chassis and the bottom pod plate are level when the car is at a static state.
While we are on the subject of chassis plane, I have found that the car is much more stable if the front of the chassis is slightly higher than the rear of the chassis when measured on a level surface.
You can change the dampener plate springs to a stiffer or softer spring. This will modify the side to side dampening as well as using different types of lubes or grease on the plates although, finding these springs can be a challenge as they are none specifically made for this adjustment. You can also change the top plate on the motor pod to a CRC top plate or a Speedmerchant top plate and use dampener tubes instead of the dampener plates.
