ENFORCER GBX3! Within this kit you will find a race

winning car with over 25 years worth of CUSTOM WORKSCUSTOM WORKS

CUSTOM WORKSCUSTOM WORKS

CUSTOM WORKS design and quality. In order for you to realize

this race car’s winning potential it is important to follow the written text along with the pictures included.

The steps required to build this car are very easy, as long as you read before you build.

The instructional format for building this car is to open each bag in alphabetical order. Each bag of

parts will be broken down into “Steps” thru the manual. All parts and hardware needed to complete

all steps for each separate bag, will be found in each individual bag. There is no need to steal screws

from other bags. In the rare event you need to look in a different bag for a certain part, it will be

noted clearly in the instructions.

Considering the various dirt or clay surfaces that Dirt Oval cars are raced on today, the Enforcer GBX3 has

been designed to be competitive on high bite and well groomed clay tracks with rubber or foam racing

tires. The instructions will build the kit using the most verastale set-up Custom Works has found in testing

on different types of tracks, however there are various other suspension configurations available to you

that you may find more suitable for your local track. For updates and more proven set-ups login to

CustomWorksRC.com.

All hardware (screws, washers, nuts, etc…) are referred to by size and type in the instructions. To

help clarify which screw or nut the instruction is calling for refer to the HARDWARE REFERENCE

supplement. The size of the screw or nut should match the “shadow” of the same piece very closely.

Screw ID’s are: FHFH

BUILDING TIPS:BUILDING TIPS:

BUILDING TIPS:

-Parts are made with tight tolerance and held to the side of a “snug” fit as wear is expected over time. Try as we

may, occasionally a burr may remain in a part and fit more tightly than desired. It is ok to use 400 Grit

Sandpaper or a .125” drill to SLOWLY relieve a part from time to time. Suspension components should always

pivot and swivel freely but not sloppily.

-Using some type of thread locking fluid is suggested for all parts where metal screws thread into other metal

parts. We suggest using a lite setting strength thread lock for the reason you may want to take the screw out

one day. Remember it only takes a very small amount to secure the screw.

-Do NOTNOT

NOTNOT

NOT use power screwdrivers to drive screws into parts. The fast rotation speed can easily melt and

strip plastic parts or cross-thread into the aluminum parts.

-Lightly sand the edges of graphite pieces using a medium grade sandpaper to avoid splinters. Run a thin

bead of Super Glue around the edges to give pieces greater durability.

TIP: To press clip in easiest, compress the clip

so the diameter is a little smaller.Insert open

end of clip first, working counter-clockwise to

the bent end as shown.

- Snap Pivot Ball into the 5228 Ball End. Thread the

Ball End onto the Med Shock until the Ball End is

flush with the end of threads on the shaft. Do the

same with the 5235 Ball Cup to the Short Shock.

- Press 1432 Eyelet Cap into 1431 Threaded

Shock Cap so that guide in the Eyelet Cap lines

up in the recess in the Threaded Shock Cap.

- Press the 1437 Firm Bladder (BLACK) into the

Threaded Shock Cap so the dome of the

bladder points away from the Eyelet Cap.

- Thread 1433 Spring Collar onto the

Shock Body.

-NOTE: See shock filling tips for more

instructions.

SHOCK FILLING INSTRUCTIONS:

2) Slowly move the

shaft up and down

several times to allow

air bubbles to escape

to the top.

1) Holding the

shock upright, fill

with oil until the

top of the body.

3) Refill with

oil to the top

of the shock

body.

5) Move the shock shaft in and out a few

times and then push it all the way in. It

should be easy to push the shaft in until

the eyelet hits the body.

4) Thread the Eyelet Cap

assembly onto the Shock

Body until it is hand tight.

Oil should seep

out of the bleed hole

in the Threaded Cap.

6) Then the shaft

should push itself out

to its full length

slowly.

7) If the shock does not push out

this far there is not enough oil in

it. Add just a little oil and try

steps 5-6 again.

8) If the shockrebounds too fast , or you cannot push

the shaft in until the eyelet hits the body, there is too

much oil. Loosen the cap about 2 full turns and pump

out a small amount of oil by pushing the shaft in.

Retighten the cap and try steps 5-6 again.

TUNING TIPS:TUNING TIPS:

TUNING TIPS: These are some general guidelines for optimizing handling performance.

None of these “tips” are EVER set in stone. On any given day this manual or any chassis

engineering book or guru can be proved wrong by the stop watch. A good way to approach

chassis set-up is to try one change, practice it, think how the car felt different from before, and

compare lap times from the stop watch…..this will never fail.

CONGRATULATIONS!!!CONGRATULATIONS!!!

CONGRATULATIONS!!!

You have now completed the assembly process of your

new Custom Works Enforcer GBX3! In the next section of this manual you will find some basic

setup hints and advice. It is important to remember that all tracks and racing surfaces are

different. Therefore the suggestions we give you are general in nature and should by no

means be treated as the only options.

- Bent Suspension Pins: Remove shocks to check

free movement.

- Bound Ball Joint: Should spin free on balls

while mounted to the car.

- Bent or Loose Camber Links

- Wore out Bearings or Completely Seized

Bearings

- Chunked Tire: Check to see if Foam or Rubber

Tire is still glued to wheel.

- Loose Screws: Especially Chassis Screws, add

Blue Loctite to prevent.

- Shocks: Either Bound-up or Out of Oil. Must

swivel freely on mounts.

- Foreign Objects: Unlucky Dirt/Stones

preventing Suspension or Steering Movement.

MAINTENANCE:

Occasionally dirt will get into the moving and pivoting locations in your car. It is best to

periodically clean your car to keep all the suspension components moving freely. Read the tips

below to keep your car running at its best!

- Begin by removing the majority of the dirt using a small brush, toothbrush, or compressed air.

- Compressed air is ok to use, be mindful to not FORCE the dirt into the radio gear, transmission,

bearings, or air filter. Typically these items only have dirt on them, hitting the dirt with the

compressed air puts dirt

ININ

these parts!

- Tires, either foam or rubber are best cleaned using water or cleaners like Simple Green (TM). Simple

Green also does a great job cleaning car parts as well. Lightly spraying car parts (NOT radio

components, transmission, air filter, or bearings) with Simple Green and blowing off with compressed

air or wiping the parts using the paint brush is a great way to clean in a hurry.

- Another R/C friendly cleaner is WD-40 (TM). After the car is clean, very lightly spray the car

components and bearings (NOT radio components, transmission, or air filter). Use your brush or

compressed air to remove the extra WD-40. This will lube your bearings and leave a protective

coating on the parts making it easier to remove dirt later.

- Differential Maintenance is needed when the action of the diff feels “notchy”. Usually cleaning the

diff parts, re-sand the thrust and diff plates with 400 paper, and lube appropriately will be all that is

needed to bring back to new. Ignoring your differential will lead to handling woes and increase

transmission temps, which will cause part failure.

Camber Gain:Camber Gain:

Camber Gain: Angle of the Camber Link relative to the Suspension Arm. Lowering the camber

link on the shock tower OR raising the camber link on the castor block will INCREASE the

camber angle of the tire when the suspension is compressed. Raising the camber link on the

shock tower OR lowering the camber link on the castor block will DECREASE the camber

angle of the tire when the suspension is compressed. There is not a “correct” set-up and once

again too much of anything is generally bad. This will help change the “feel” of the car thru

the turns.

Camber Link Length:Camber Link Length:

Camber Link Length: Comparing this to the length of the Suspension Arm from each pivot

point and keeping the Camber the same, making the link

shorter

will decrease traction for

that corner of the car while making it

longer

will increase traction for that corner of the car.

Once the camber link is equal to or greater than the Suspension Arm pivots, the gain of

traction ends. Also a shorter camber link will increase camber gain and a longer decrease

camber gain.

Shock Angle:Shock Angle:

Shock Angle: Leaning the shock toward the car is effectively like changing to a

softer

spring.

Standing the shock closer to vertical is effectively like changing to a

stiffer

spring. Try when

the car is working well and when one spring change is TOO much for your set-up.

Ride Height:Ride Height:

Ride Height: Check by pushing the chassis down once or twice to simulate bumps on the

track. Having the front end

higher

than the rear will make the car increase rear traction

especially out of the turn. Having the front end

lower

than the front will make the car increase

front traction especially entering the turn. Generally its safe to start the car with the ride

heights even.

Rear Toe-In:Rear Toe-In:

Rear Toe-In: Front edge of car tires point

toward

the chassis as viewed from above the car.

Increasing the angle toward the car will increase rear traction while decreasing front traction.

Decreasing the angle will do the opposite.

SET-UP GLOSSARY:SET-UP GLOSSARY:

SET-UP GLOSSARY:

Caster:Caster:

Caster: Angle of the kingpin in relation to a vertical plane as viewed from the side of the car.

Increasing the angle will make the car more stable out of the turn and down the straights and

increase steering entering a turn. Decreasing the angle will make the car feel more “touchy” at high

speeds and help steering while exiting the turn.

SET-UP GUIDELINES:SET-UP GUIDELINES:

SET-UP GUIDELINES:

When looking for the “perfect set-up” it is important to remember 2 things...

1) Keeping things simple is best.

2) As you are making your set-up change, the track is changing too! Ask a local racer what the

track usually does from begining to end, especially day to night.

- Start your car’s ride height with it equal at all four corners to start. Use the shock collars to adjust

ride height by measuring the distance under the chassis when the car is sitting on a FLAT & LEVEL

surface.

- Shock collars can only jack weight and adjust the car’s handling when the car makes ALL 4 shocks

squat when the car is set down. Use the RF shock collar to adjust how the car ENTERS the corner.

Use the RR shock collar to adjust how the car exits the corner ON-POWER. Use the LF shock collar

to make the car turn in less, and off the corner more.

- It is best to have a little bit of brake drag when you let off the gas, this will allow for a more

controlable car in ALL conditions. Increasing how much the brake drags will make your car turn

into the corner harder.

Final Drive Chart:Final Drive Chart:

Final Drive Chart: The chart provided below gives you the final drive of the motor to spin the

axle 1 revolution. This chart is NOT just the pinion and spur, but has the transmission ratio

included as well.

Rear Toe Stagger:Rear Toe Stagger:

Rear Toe Stagger:

Difference in the amount of Rear Toe-In among the rear tires. Typically used

only on high bite tracks with MORE toe-in on the Left Rear tire than the Right so the rear of

the car helps turn the car LEFT under acceleration.

Wheelbase (Front End):Wheelbase (Front End):

Wheelbase (Front End): Wheelbase is the distance between the front and rear axles.

Running the entire front end assembly in the forward position makes the wheelbase longer

and therefore more stable on long/fast tracks with flowing turns. Running the entire front

end assembly in the rear position make the wheelbase shorter and therefore more suitable for

short-tracks where you are constantly turning.

Wheelbase (Rear End):Wheelbase (Rear End):

Wheelbase (Rear End): This adjustment uses the plastic spacers on the kingpin the rear

bearing carrier rides on. With the spacers in front of the carrier it will lengthen the wheelbase

but will increase steering. If the spacers are behind the carrier it will shorten the wheelbase

but increase rear traction. This is completely backwards from how it works for the Front End

only because in the rear of the car you have the weight of the motor and the torque it creates.

Shortening the wheelbase here makes more of the car hang over the rear tires and promotes

more weight transfer.

- To determine the final drive in your car:

1) Divide the Spur Gear by the Pinion Gear, which

equals a “Ratio”.

2) Multiply the “Ratio” by the “Transmission Ratio”

which will equal your “Final Drive”.

***Transmission Ratio = 2.4 for this car.***

- Gearing choice can vary greatly depending

on track size, surface type, amount of traction,

you motor and driving style. For starters

consult your local hobby dealer or fellow racer

at your local track for the ideal gear choice for

your application.
