E2025 - MBX8 Worlds Edition - April, 2019

MUGE0240: Wide Offset Wheel Hubs 1mm 2pcs; The 1mm wide offset wheel hubs will increase stability and cornering.
MUGE2146: Inline Front Uprights; The E2146 inline front uprights have smoother steering compared to the stock E2147 trailing front uprights and work great in high traction conditions. E2146 uprights can be used with both CVA and universal style driveshafts.
MUGE2168: -3mm Front Upright Arm; The -3mm front upright arm improves the initial steering response and make the vehicle more stable through the middle and exit of the corner.. The new upright arms also reduce bump steer and make the vehicle more predictable in bumpy conditions.
MUGE2235: 46T Spur Gear; The 46 tooth HTD spur gear provides a great balance of acceleration and top-end speed.
MUGE2252: 12T Pinion Gear
MUGE2254: 42T Conical Gear; The optional 12T bevel gear when used with the 42T conical gear will change the final drive ratio and increase acceleration.
MUGE2260: Center Joint Cup.
MUGE2261: Center Front Dog Bone (84.5mm)
MUGE2262: Center Rear Dog Bone (115mm); The front and rear-center dogbones for the MBX8 reduce friction from the stock universal driveshafts. Less friction will give the vehicle a more efficient drivetrain, increase acceleration, and provide more traction. The dog bones are lightweight, durable, and will increase traction.
MUGE2428: Rear Wing Stay +15mm; The +15mm wing mount has more adjustment and will help increase mid corner rotation and be more stable in high speed conditions.


E2021 - MBX8 1/8 Nitro Buggy Kit

Chassis:
The MBX8 chassis features a new design that improves traction and stability in bumpy conditions and on the exit of corners. The steering post are also keyed into the MBX8 chassis for easier maintenance.

Differential & drive train:
High Traction Differentials are included in the MBX8. The Mugen Seiki HTD provides increased acceleration, longer runtime, and more consistent handling. The HTD's also increase stability, traction, and improve handling in bumpy conditions. The HTD has a new larger volume diff cup to increase consistency during long main events. This makes it easier to time rhythm sections, better in bumpy and low grip conditions, helps to increase traction, and increases fuel mileage.

The new gearbox makes allows you to remove and service the differentials without detaching the suspension arm mounts. Easy access to the front and rear differential.

New straight cut 13T bevel gear & 44T conical gear. The new straight cut bevel and conical gears increase acceleration, runtime, and efficiency. A free and efficient drive train will also increase speeds while cornering.

Light weight one-piece wing mount:
The new lightweight one-piece wing mount lower the center of gravity. The position of the wing and wing mount is optimized to improve the performance of vehicle. The height of the wing mount is adjustable. This allows you to control the down force on the rear of the vehicle by simply raising or lowering the mount on the shock tower.

Light weight high down-force wing:
The new IFMAR legal wing is lightweight and provides amazing down force and cornering. The underside of the wing uses a new design to reduced weight and creates additional down-force.

Suspension:
New suspension mounts. The FF/FR/RF/RR are new for the MBX8.
The front and rear lower arms use a new impact resistant material for increased durability. The new arms are box-shaped and include arm stiffeners to reduce flex and increase durability. Adjusting the hardness of the lower suspension arms is now possible. This allows you to fine tune the steering and traction from track to track. CFRP plates will be released as an option part.

Center differential mount & plate:
The center differential mounts use a stiffer material and has a new top plate to reduce chassis flex and increases clutch bell, spur gear, and clutch bearing life. The reduced chassis flex also provides more consistent handling in all conditions. The top plate design also makes it easier to adjust the brakes and easier maintenance.

Enclosed Battery box and updated carbon fiber radio plate:
The MBX8 still uses a flat 2S Lipo or Life battery, but the receiver battery is now enclosed in a molded battery box. The battery box allows for quick and easy access to the battery. The molded box also helps protect the battery from hard impacts. The battery box is mounted to an updated carbon fiber radio plate.

Other new parts and upgrades:
Body, Clamping Servo Saver Nut, F/R Shock Towers, Front bumper, Front center and rear center universal joint.

Any info on the front upper pill adjustments and their effects? Wish mugen would put out a chart showing the angles for the rear also.

I didn’t really feel a difference but it looks better than the stock body and if you are running nitro it offers some protection your engine, because it sits higher.

By running the 44/13 in the front, it will pull the car more since the front will be spinning a bit faster than the rear (42/12). So if you like a car that you can slide through a turn and have the front pull you out of the slide then this is for you and give it a try.

Hi
The car needs some time to work properly when it is brand new.
Often the differentials are not built correctly.
Or filled with too thick oil.
The diffs are super important!
The rear arms need some play.

Has anyone tried using HB springs on the MBX8R to achieve the proper ride height, without cutting the shock ends?

Hello! I'm new on Mugen, just bought an MBX8R and looking for an undergear diff set for the rear end. Can someone tell me the correct codes for them? Diff ring and bevel gear.
Thanks in advance

Hi, can someone briefly explain to me what the difference between the Worlds Edition, and the R version is? From what I have read online the R version is the latest, but I can't figure out the differences between the 2. Someone I know is offering to sell me there Worlds Edition that is the reason why I am asking.

Most noticably new narrower rear pivot with longer rear arms (new C-D Block)
New rear +3mm uprights
New sun gear in diffs
New brake springs
New front Pill holders with new bushings
New front shock tower

If I'm not mistaken these are all the changes. Hope this helps!
