Black and Silver Versions available.

The design is a flexible platform for RWD conversion and supports many of the Yokomo DIB / DRB and Drift Package MR4TC compatible suspension and steering components.

Flexible battery location, 5 servo locations and 4 steering mounting variations give you control over your setups.

This conversion is targeted at those already with a full tune 4wd DRB wanting to move to RWD, but not throw away their DRB, or those already having converted their DRB to RWD but not finding the balance they require. Stock front end DRB components will most definitely require change. At a minimum the V2 Y arm setup is a good starting point but the steering knuckle design should be considered for RWD conversions.

This chassis was developed on the most difficult of surfaces. Ultra low grip polished concrete. RWD drift requires traction and chassis balance. Keeping the balance point directly over the rear wheels avoids the pendulum effect from diffuser mounted setups. However If your circuit has a high traction surface, a diffuser mounting point is provided and after market options can be fitted.

Box and Components.

Two versions include 4K narrow weave SSG and wide weave Black Twill carbon.

Both are the same design spec, however due to variance in raw materials, the Twill is slightly thicker (2.5mm) and therefore slightly more rigid. Silver is (2.35mm)

Design image has been kept in line with the later range of Yokomo HT chassis, providing a link to the original.

Silver Surface Graphite chassis set includes components that focus on flexibility of design and a change in weight distribution. The components fall into two categories.

Rear Conversion Components
These components convert the current DRB to a RWD rear motor layout.

2.5 mm Carbon Lower Deck
2.0 mm Carbon Upper Deck
2.0 mm Battery Mount

Weight Shift Components
These components follow the current trends in D1 to allow higher ride height and longer stroke suspension taking advantage in chassis weight shift, pitch and roll for a more dynamic chassis. The can be used with any DRB Chassis.

5.0 mm ( 2.5mm x 2 ) Bulkhead Spacer Set ( 5pcs Motor / Pulley / Centre / BulkHeads )
3.0 mm Carbon Front Shock Tower (5mm lower)

2.0 mm front Servo Mount (optional)

RWD Specific parts.

27 piece carbon set. (note, type c support brace not pictured)
4x Carbon battery spacers and 17x12mm / 4x30mm stainless screw set.

Almost all combinations of DRIFT PACKAGE compatible suspension are supported.

The weight shift components combine with a rear focused layout which targets the performance oriented RWD pilot. Reverse motor direction will dictate a pulley conversion or the use of an ESC that supports Reversing. Accuvance systems have this function built in.

Twin servo mounting is possible. Front wiper extensions work with DRb wipers.

Note a 1mm spacer to lower the wiper is required for this steering version.
Ackerman can be setup with an optional turn buckle that will fit through the bulkhead (where once a one way bearing would have been installed.)

Overdose
OD2130 Ball End Set (Highly recommended for clearance of knuckle)

A great alternative I trialed on the Prototype is the Drift Package Long Wiper and knuckle. Mounting the servo centrally also provides excellent balance. I would recommend this setup as a proven option.

Yokomo Long Wipers would require these parts
D-163 Aluminum steering bell crank for 2WD DRIFT Conversion PRO/RS 201
BB-84-4 Bell Crank Bearing
D-029 Aluminum Steeling Bell Crank Post
and... some spacers.

R31WORLD GRK Slide rack support is also available. Note.

This is not the most flexible option as setup takes precise measurments.

R31W237 New Steering Rack Set
R31M081 Slide Steering Rack Mounting Set

NOTE:

High battery position and especially long battery support will influence body clearance. However most bodies seem to allow the battery to fit just at the rear window.

Be aware of this point when using full size battery designs.

DRB-REW Performance is targeted for the advanced user.

From smooth flowing style...

... to aggressive initiation and holding of angle. You have control over the setup.

The DRB-REW was designed and tuned on low grip polished concrete. The most difficult surface for tuning where grip is at an absolute minimum.

Long, high speed slides with ease and control.

Predictable performance as expected from the DRB high end chassis kit.

No matter what your style. Setup is individual.

Rear Motor / Rear Battery designs have a slight weight imbalance on this surface. REW Weight is centred just in front of the rear axle. Further fine tuning can be performed with an Orion Weight Shift Battery pack.
