MR-03 Mod-GT 2013 setup.

Just a small piece about my latest Kyosho Mini-Z modified GT setup.

This setup are very driveable and consistent from track to track.
For me, this works on both high, med and low grip tracks with very small adjustments. Mainly tires and offsets. Tires are very track dependent, so I will keep these out.
This setup is basically the same I used to win the latest PNWC Mod GT Race in Sweden.

Mini-Z MR-03

Front end.

• Low profile reverse king pin setup.
• Reflex Racing raised lower tower bar
• Reflex Racing standard silver spring
• Reflex Racing knuckles (Mini-Z Norway "no slop" inserts with lower 0,4mm sleeve as shim. More on this later)
• Reflex Racing King pin
• Reflex Racing extra long upper arm
• Reflex Racing Adjustable upper tower
• 0,3mm raised roll centre
• 0,3mm between cam and adjustable arm (Roughly 1 degree camber)
• 2 degrees caster
• 2mm shim on top for adjusting droop/ preload
• 0,2mm droop

Chassis

• Regular black chassis
• Grey SS front chassis plate for added front end stiffness
• Reflex Racing aluminium top deck
• Reflex Racing T-bar mount without pivot screw
• 98mm wheelbase
• Reflex Racing bearings

Rear end

• QteQ soft X-fibre FRP T-bar
• Reflex Racing 945 motor mount
• Reflex Racing Diffuser
• Reflex Racing Side dampers
• Reflex Racing Silver springs with some preload
• Reflex Racing top shock standoff. Shortened.
• Kyosho oil shock
• Reflex Racing oil shock spring. Silver or gold depending on grip levels. Preload until chassis is level
• RSD Top damper mount. 

Differential

• Reflex Racing diff halves and left hub
• PN Racing aluminium diff shaft
• Reflex Racing V3 spur
• Reflex Racing 2mm spur bearing
• Kyosho pressure plates
• Reflex Racing ceramic diff balls
• Reflex Racing abec 5 outer diff bearing
• Reflex Racing O-ring

Fluids

• Kyosho 15000WT grease in side dampers
• Kyosho 500 WT oil in oil shock
• Kyosho ball diff grease in the differential. Important. Nothing else gives me the correct feel. This grease contains fibre glass particles that lets you run the diff much looser and still grip. Results are a smoother diff action, that are more consistent, and since you can run it very loose you will have lots of turn in without sacrificing accelleration.

Grip dependent stuff

High grip

• Body. Audi R8. Super light, and quite agressive
• Offset front 2 offset wheels, with 0,5mm shim, plus the 0,4mm wider lower tower. In total this gives 2,9mm offset. 
• Rear 3,4mm offset
• Slightly harder differential
• Added weight underneath chassis.
• Silver oil shock spring

Low grip

• Body. Lexus SC430. Light weight, and very easy to drive
• Offset rear. 1 - 2mm. Depends on grip level. Less offset when grip are low. Increase offset when grip increases
• Offset front. 0 - 1mm. Depends on grip level. Less offset when grip are low. Increase offset when grip increases
• Slightly looser differential
• Gold oil shock spring

Mini-Z Norway "no slop" inserts.

These are made to remove some of the unwanted slop in the knuckles. Slop in the front end are not always bad, as it often gives you an easier car to drive, but for added precision this is the way to go.

They are drilled to 1,97mm internal diameter, so they remove all play between knuckle and king-pin. They also increase the length of the knuckle with 0,4mm. This is done for two reasons. I always lower the car with 0,4mm, and they support better against the king pin.
