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.

Well, that is reassuring by 30tooth then if that is the case. It just shows how good the car is.

Look at the MP9, its a great buggy (used to race it) and it just got small subtle changes throughout its tenure.

I guess we will see, once it hits the track, see what Robert and Drake have to say. I am excited to see how well it does on a European mixed surface track. I think based on the changes, it will do very well.

Well, the last car I have seen any coverage on, was Roberts MBX7R, during the Winter Edition Race. Everything looks as a 7R, with regular Shock Caps, running CVD's with steel axles / outdrives, carbon towers...

Mugen is good at keeping their development top secret. They showed up in Argentina with a brand new mbx7 and nobody knew that something was coming (and at that point the car was basically production-ready). I would be very surprised if they raced the mbx8 on any event before the official release. Maaaybe some individual parts.

Thats what I was getting at, he did not really have anything new visually obvious at the Winter event. And that if he were to try anything it would be small as stated.

I am sure after the official Release, we will see the team drivers cars on FB!

Same thing people blowing out their 7r for cheap. 90% of what I wrote you can already do to the 7r, maybe even 99% if you DIY or use parts from other car (the wing mount). I thought this day wouldn't come but Xray got their act together with the '18, ball is on mugen side so I'm eager to find what's new.

Sorry man, it's another joke like the one I've made for the b64.

The current car can be much better, I haven't got that much hands-on experience but there's a lot of potential. If you want to help me develop a setup for you just PM me.

What light weight drivetrain parts exactly are you referring to? And what are side mounted brake calipers? Example buggy that has side mounted calipers?

Thanks for the info, btw..

So back on topic then. Perhaps the new car will come with a dedicated Lipo Box. One.thing i would change is the upper steering post fasteners, from countersunk to either button head or regular Square Head Hex !!!

Drake said:

- same drive train
- new, significantly stronger arms (compatible w mbx7r)
- new wing and wing mount
- new towers
- new chassis

Car looks very similar to the 7r but a lot of details have changed.

No split Center diff mount.
