V12-CE SETUP MANUAL

The new, adjustable rear pod is dif-

ferent – ride height is changing by 

swapping the axle bearing cams; 

rear spring tension is only used to 

get the required chassis droop and 

is then left alone.  The means no 

washers are needed under the front 

pivot ball, even if larger tyres are 

used, resulting in your whole pod 

(and CoG) being up to 2mm lower.  

Just remember that when you 

change the cams your gear mesh 

will also need changing.

3.C. REAR END

Use a “Low” cam as your rear 

wheels wear down.

Use a “High” cam when your 

rear wheels are new and up to 

51mm diameter.

This is a new part for this kit and 

has a big impact on car handling.  

The short story is that it affects 

how the rear of the car behaves 

as you go through corners.  The 

longer story is that oil thickness 

changes the speed of the piston, 

which changes how far/fast the 

chassis can roll as you corner 

which, in turn, affects how weight 

is transferred and the outside tyre 

is loaded up.  Rear spring stiffness 

/ diff tightness also come into play 

and you risk some really poor han-

dling if any of the settings are out!  

Getting it right is a careful balance 

of oil thickness, diff tightness and 

spring rate.

Always keep the damper tube 

topped up with oil. NOTE: There 

is a difference between the units 

used to measure oil thickness.  

WT is not the same as CST so 

30,000wt oil will be different to 

30,000cst oil.

30,000wt oil is good on larger, 

faster tracks and down to 

12,000wt is good if you need 

faster weight transfer and quicker 

steering response on tight tracks.  

Re-fill the tube every 3-6 runs, 

whether it feels like it needs it or 

not - wipe excess off the rod and 

clean the inside of the tube with 

motor spray.  Pour a small amount 

of oil into the tube and smother 

the rod’s grooves in the stuff.  

Slowly slide the rod into the tube 

and give it a bit of a bounce and 

twist as you push it in so that the 

oil is evenly distributed.  Expect 

to get some oil squeezing out of 

the breathing holes and some left 

on the rod once it is fully in – this 

way you know it is completely full 

each time re-fill it.

As for handling: 

1. Rear end ‘hops’ on acceler-

ate out of corners - softer rear 

springs, lighter damper oil or 

loosen the diff.

2. Inside wheel front wheel lifts 

(or car grip rolls) in corners - 

harder rear spring and damper 

oil use smaller diameter, harder 

tyres.

3. On-power understeer out of 

corners - loosen the diff; tighten it 

for oversteer.

4. DAMPER TUBE
