The new bypass shock case will be released to smoothen the car at corner entry and small steering value.It will make the car less sensitive, so it is suitable for carpet and high grip conditions.

In certain track conditions it will smoothen the corner entry and build up maximum grip in mid corner, resulting an easy behave of the car with good corner speed.It is highly recommended for high grip conditions as well as on carpet.It is more likely to absorb the bumps in asphalt track, so the movement of the car will smoothen and possible to turn smaller and faster.

This completely new concept shock tower eliminates the resistance from the shock absorberwhen the suspension is lowered, dramatically improving stability when driving in the bumnpson the track, or on the curbs in the corner.It also improves the stability of the rear in small corners that enter at high speed and cornersthat require quick turning. The above effects are more apparent when using softer tires.Note:A2542 is for front, and same left and right. A2543 is for rear, and same left and right.You need A2542x2 and A2543x2 for one car.

Suspension: New suspension mounts and geometry. The MBX8R uses new narrow RF (C) and RR (D) pivot blocks with new pivot inserts for increased tuneability. New longer box-shaped suspension arms and arm stiffeners. The rear arm uses an impact resistant material for increased durability. Adjusting the hardness of the lower suspension arms is possible with optional CFRP plates. The rear uprights are also new for the MBX8R. The molded uprights have CFRP plates to adjust rear roll center. New front shock tower and upper front arm mount use new pivot inserts for increased tuneability. Chassis: The MBX8R chassis features a slightly new design to accommodate the new suspension geometry. Clutch: New 4 shoe clutch. The MBX8R comes with a complete new 4 shoe clutch from Mugen Seiki. The new 4 shoe clutch was designed to be easy to work on and more tunable. This clutch features a 34mm aluminum 4 shoe flywheel with removable steel pins. The new clutch has a unique way of adjusting spring tension to tune the engagement to suit your engine, track conditions and personal preferences to optimize fuel consumption and performance. Multiple clutch springs will be available as an option parts. New vented 13T clutch bell will be included in the MBX8R kit. The MBX8R will come with two aluminum and two carbon shoes in the kit. Differential and drivetrain: High Traction Differentials are included in the MBX8R. 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 diffs use 20T internal gears to improve consistency and to have smoother operating differentials. This makes it easier to time rhythm sections, better in bumpy and low grip conditions, helps to increase traction, and increases fuel mileage. The MBX8R comes with 12T bevel gear and 42T conical gears and 46T spur gear in the kit. New wing and wing mount: Lightweight high down-force wing allows more air to flow to improve jumping. The new IFMAR legal wing is durable, lightweight, and very stable on the track and in the air. - Revised rear wing mount will provide additional downforce and increase durability. CFRP wing plate will be available as an option part. - New S bent air filter boot and high-volume filter housing. - New brake override and caliper springs for smoother more consistent braking. - New 90-degree fuel tank fitting for cleaner fuel line routing. - New sway bar collars to reduce sway bar movement. - Emulsion shock caps are included in the MBX8R kit and can choose between diaphragm or emulsion. - New high-volume battery box and radio plate. - New mount & receiver box to which various manufacturer’s electric switch can be attached. - Alum. wing washer - Rear upper arm link compatible with the new rear uprights. - Harder and lighterweight F/R lower arms will be available as an option part.

6x13x5 Ball bearings are mainly used for supporting MBX8 bevel gears (Front/Rear)and Gear Housing / Middle shaft of MTX7.NMB Bearings are more durable than the standard type.

This is CFRP plate to be installed between servo saver and front bulkhead on the radio plate.It’s depending on the track, but it’s sometimes improves the stability when open the throttle by installing this plate.

The additional muffler stopper prevents the set screw from loosening and that the muffler come off due to vibration and heat while driving.
