The story of the 8IGHT platform is the story of a champion - one that encompasses multiple ROAR national titles in addition to major wins on the international stage. The 8IGHT 4.0 buggy builds on this championship-winning heritage with updates to the suspension geometry and drivetrain layout that make it both easier to drive and tougher to beat.



DURABLE 4MM HARD-ANODIZED 7075 T-6 ALUMINUM CHASSIS
REDUCED FRONT DRIVESHAFT ANGLE
BALL BEARING THROTTLE AND BRAKE ACTUATORS
LARGE-BEARING SPINDLES AND HUBS
REVISED CHASSIS SIDE GUARDS
LARGER ENGINE MOUNT THAT REDUCES CHASSIS FLEX
15˚ CASTER BLOCKS WITH ADJUSTABLE SPINDLE HEIGHT
ALUMINUM SHOCK CAPS WITH THREADED BLEEDER HOLES
MOLDED DRIVESHAFT AND DOG BONE BOOTS
ALUMINUM SHOCK TOWERS WITH UPDATED CAMBER LINK AND SHOCK LOCATION HOLES
WEIGHT BALLAST-READY TO MEET ROAR MINIMUM WEIGHT REQUIREMENT
THROTTLE ACTUATOR BRACE
CAB FORWARD BODY
REVISED SHOCK BUSHINGS
IMPROVED ACKERMAN SCREWS

REVISED SUSPENSION GEOMETRY

The adjustable, 15-degree caster blocks make it possible to tune dog bone plunge by changing the height of the spindle.

REVISED SHOCK TOWERS

The shock towers have also been redesigned with new camber link and shock mounting holes that provide more tuning options for evolving track conditions. The result is a buggy that lets drivers of all skill levels turn faster lap times with fewer mistakes, particularly during brutal, hour-long mains.

OPTIMIZED DRIVETRAIN LAYOUT

The engine mount has been repositioned to reduce front driveshaft angle so more power makes it to the front wheels. Molded rubber boots on the universals and center drivetrain dog bones increase U- joint life by holding lubrication in and keeping dirt out.

LARGE-FOOTPRINT ENGINE MOUNT

In addition to its new position, the engine mount has been designed with a larger footprint that substantially reduces chassis flex and fatigue underneath the engine when racing on high-grip tracks.

LARGE BEARING SPINDLES AND HUBS

Front spindles and rear hubs have been revised to accept a larger 8 x 16 x 5 outer bearing for increased durability.

REVISED CHASSIS SIDE GUARDS

The chassis side guards have been updated for a better fit. They also feature indentations for the Velcro body strips.

WEIGHT BALLAST-READY

The chassis has been designed to accommodate hard-mount ballast weights so it is easier to meet the ROAR minimum weight requirement.

CVA AND CENTER DRIVE BOOTS

The CVA’s now are protected by rubber boots to further improve durability by keeping grease in and dirt out. Additionally the center front and rear dogbone coupler now includes rubber boots to do the same job.

REVISED THROTTLE ACTUATOR

The revised throttle actuator now uses bearings to further improve throttle and brake response. It also features a new brace that prevents flexing during heavy braking.

BLEEDER SHOCK CAPS

New bleeder shock caps and internal seals allow for easier shock rebuilds while using an emulsion shock set-up. New bushings that press into the shock cap further improve durability.

OPTION PARTS

A myriad of option parts are included which include lightweight 48 tooth spur gear, lightweight out drives, +1mm rear hexes, capped wheel nuts, aluminum bearing inserts, alumimum adjustable hinge pin braces and a host of other tuning parts.

CAB-FORWARD BODY

The cab-forward body moves aerodynamic pressure further forward on the car, which improves steering.

DON'T COME HERE TO B17CH AND MOAN ABOUT THE SAE HARDWEAR. THERE'S ALREADY A THREAD FOR THAT HERE

I had some time this afternoon and thought most of you would appreciate a thread with a fresh start for the new platform

Thank you Alan. You're a good dude.

Will the CV Boots work on the 3.0?
Will the 4.0 Spindles work on the 3.0?
Will the Pinion Spacers work on the 3.0?

Based on the list above, I think some of the parts are not completely necessary if you are upgrading the 3.0 to 4.0. Some confirmation would be great.

I have purchased the aluminum rear hub carriers, no need to update in my opinion, just for a bigger bearing.

Can the throttle linkage bearings work in the 3.0 setup? With some modifications.

Just asking, I will be getting my 4.0 Kit shortly.

RCSureStart

You'll need the 4.0 throttle/brake linkage for the bearings to fit, you won't be able to use the 3.0 linkage. The fittings for the brake cam are also new so you'd need to replace those too.

Have a look at my blog on maxbashing dot com of the build to give you an idea of the new parts (still can't paste links!)

Thanks

It isnt until you put both chassis next to each other that you can see the improvments tlr made to the 4.0. Great to see they are tryin to reduce wear in the hard parts with the boots.lets face it. The rebuild money is in hard parts imo. Tray is almost dun and my new whip is ready. Emoultion setup in the new shocks is badazz also.

I ordered the emulsion caps for my E 3.0 and put them on tonight. Super easy to build and bleed and they seem to work much more smoothly on the car as well. I highly recommend them to everybody.

Austin's dad

What oil are you running in your shocks?

Curious to see if any of the team drivers run the shocks emulsion or with bladders.

Socket

iTrader: (61)

The few I've asked have only ran bladders. I'm super curious of emulsion as well.

I'll be building mine emulsion for next weekend.

The biggest change, is the motor/driveline moving. This changes the handling on the car by a HUGE amount. It really drives a LOT different, and a lot BETTER.
