For XRAY to win the European Championship title feels fantastic for me on a personal level, as it’s the result of years of hard work. Team XRAY has come close many times to winning the Modified class at European Championship, achieving multiple TQs and podium finishes – even with myself being close to taking a win in previous years, too. Over the years we never gave up and continued our hard work, and it has paid off. I want to congratulate the entire team for this win that is a result of a dedicated teamwork. Together we have achieved great things! We will continue to work hard with our development of the T4 to stay ahead of the competition. The T4'16 is another step forward for this race-winning platform!

2016 All-New

  • All-new chassis design
  • All-new motor mount flex system
  • All-new top deck
  • All-new rear suspension holder for ARS
  • All-new front ECS drive shafts
  • Improved traction
  • Improved steering characteristics
2016 All-New


The T4’16 features a new chassis that was redesigned to fit the new motor mount plate to allow for more chassis flex adjustment.

The ultra-narrow chassis is only 86mm wide and with the variety of chassis flex adjustment generates the required traction and gives excellent steering characteristics. The chassis design helps the T4’16 to be suitable for all track conditions.

The 2.2mm chassis is CNC-machined from premium-grade graphite material. The chassis features pre-drilled holes for optional parts such as chassis weights, graphite motor guard, graphite adjustable battery holder, and battery strap.

Weight distribution and balance characteristics have been optimized. Due to the increase in LiPo capacity – resulting in additional weight and heavier electronics to handle the increased power of modern brushless systems – the chassis was designed to allow the weight to be moved as close as possible to the chassis centerline in order to maintain proper balance.


Motor Mount Plate.

The new motor mount plate features new extra additional chassis flex adjustment positions.

The motor mount is part of the left layshaft bulkhead to eliminate unwanted tweak. The motor mount is connected to the chassis by 2 screws under the layshaft, and features the mounting system in front of the motor. The motor mount system consists of a motor mount plate that is connected to the motor mount by a button-head screw which is more tweak-free compared to a countersunk screw. The motor mount plate is connected to the chassis via an M3 nut and an extra countersunk screw can be placed ahead of the nut if more reinforcement is needed, or the nut can be removed and 1 of 2 new holes can be used as extra flex adjustment options.

The layshaft part of the motor mount bulkhead allows the removal of front or rear (or both) screws which connect the top deck, as the bearing is fixed to the layshaft bulkhead and does not move. This improves the flex adjustability of the car to better suit different track conditions.

The motor mount is CNC-machined from premium Swiss 7075 T6 aluminum and is color-coated for a distinctive look.

Motor Mount Plate

Top Deck.

The top deck shape was redesigned to allow for more easy access to the pinion gear, thus making it easier to work on the car.

The shape of the rear portion of the top deck has been specifically designed to achieve maximum traction and in-corner steering. The top deck is machined from premium-grade 2.0mm graphite. An optional belt tensioner can be mounted to the top deck.

Top Deck

Suspension Holders.

All-new rear 1-piece suspension holder for ARS™ system ensures strength in crashes, as well as adding extra roll center positions for the ARS™ suspension.

CNC-machined from premium Swiss 7075 T6 aluminum and anodized in a distinctive orange color. XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges.

ECS Drive Shafts.

The all-new Extra-Strong ECS drive shafts are included in the kit as a standard part. The legendary XRAY ECS drive shafts are equalize the speed between the drive shaft and the wheel. With a unique 2-piece joint between the axle and the wheel, the same extreme wheel turning angle is divided into two shallower angles without joint binding. This means that regardless of cornering speed and wheel angle, the inner wheel will not bind or vibrate. Drive through the corner is more stable, more precise, and easier to drive.

With the ECS drive shafts, wheel vibrations and noise are decreased to minimum, steering is increased, and cornering speed & smoothness are noticeably increased.

Drive shafts are exclusively manufactured from special world-renowned, top-secret, self-developed HUDY Spring Steel™. The drive shafts are strategically lightened – see the hollow end of the dog bone – to guarantee the lowest possible weight without compromising strength or durability. These specially-lightened drive shafts can only be manufactured from special HUDY Spring Steel™ which was developed for extreme racing conditions. The drive shafts have been additionally hand-ground for maximum precision and to provide true rotation and unbinding drivetrain operation.

Aluminum Bulkheads.

The T4 platform – with centralized weight placement – features the smallest and lightest bulkheads ever, positioned more towards the chassis centerline to provide maximum traction & steering, and improved balance.

To accommodate the ball-bearing anti-roll bar mounting system, the bulkheads feature a special anti-roll bar mounting area where the anti-roll bar mounting collars are installed.

All bulkhead parts are CNC-machined from premium Swiss 7075 T6 aluminum and have been designed to provide the lightest and strongest possible support framework for the car.

The bulkheads are anodized in a distinctive orange color. (Note: Color may vary slightly between products.) XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges.

Aluminum Bulkheads

Upper Clamps.

The aluminum upper clamps allow for very quick & easy roll center adjustment with 4 different roll center mounting positions. All upper clamps are identical and can be used both front & rear.

Made from premium Swiss 7075 T6 aluminum, orange anodized.

Upper Clamps

Layshaft Bulkhead.

The layshaft bulkhead allows the removal of front or rear (or both) screws which connect the top deck, as the bearing is fixed to the layshaft bulkhead and does not move. This improves the flex adjustability of the car to better suit it to different track conditions and surfaces.

Made from premium Swiss 7075 T6 aluminum, orange anodized.

Layshaft Bulkhead

Anti-roll Bar System.

The wobble-free anti-roll bar system is mounted to the front & rear bulkheads via bearings from outside for extra-smooth movement and quick & easy changes and adjustment. The roll bar turns in ball-bearings for maximum precision and free movement. Anti-roll bar height is adjustable via a screw.

Anti-roll Bar System

Anti-Roll Bars.

The complete range of different anti-roll bar thicknesses is designed to work with the ball-bearing roll bar mounting system. Front 1.4mm and rear 1.3mm anti-roll bars are included as standard in the kit. Anti-roll bars have laser-engraved stripes (corresponding to bar thickness) for easy identification.

Anti-Roll Bars

Proven Suspension Geometry.

From the narrow arms, through the tiny front and rear suspension blocks, to the small and robust steering blocks, every suspension part has been specially designed to provide responsive racing characteristics in all racing conditions. Over the years XRAY has successfully gained and utilized extensive suspension geometry knowledge and self-developed suspension stiffness technology, which have been utilized when designing suspension parts. The ultra-lightweight suspension parts are molded from a special composite material that makes the parts very light yet very durable to withstand the rigors of high-performance racing.

The T4 platform features optimized suspension parts carried over from the T3 platform. The arms feature a single optimized shock mounting position and integrated anti-roll bar mounts. The rear arms feature three anti-roll bar mounts for super-fine adjustment of the anti-roll bar.

Proven Suspension Geometry

ARS™ System.

The kit includes both standard and Active Rear Suspension (ARS™) rear suspension. ARS™ offers great adjustment possibilities and driving characteristics.

ARS™ suspension consists of: suspension arms, graphite 0° C-hubs for optimal flex characteristics, hard steering blocks, and ARS™ linkages which connect suspension holders with the suspension block. The angle of ARS™ linkages –set by adding/removing shims on the suspension block and suspension holder – changes the toe-in characteristics of the rear tires during chassis roll.

ARS™ SystemARS™ SystemARS™ SystemARS™ System

Suspension Holders.

Aluminum suspension holders feature Integrated Suspension Settings (ISS) which allow super-fast & easy suspension geometry setting. This XRAY concept was first introduced in the very first XB8 and has successfully been carried over to 1/10 onroad.

Suspension holders allow more durable mounting of the suspension arms. With the suspension holders, the geometry of the car does not change even under hard crashes. Thanks to the mounting system, arms move very freely to give higher traction and the car feels smoother in corners which also positively influences steering characteristics.

Suspension holders are CNC-machined from premium Swiss 7075 T6 aluminum and have been designed to provide the lightest and strongest possible support framework for the car.

There are two types of the suspension holders, each specifically designed and chosen to provide the required characteristics – stability, traction, and flex:

  • Front of the FRONT suspension – 1-piece
  • Rear of the FRONT suspension – 1-piece for stability, easy to drive in all conditions but especially under high-traction conditions. Optional 2-piece holders give increased in-corner steering, and are recommended for use on asphalt and low-traction track conditions.
  • Front of the REAR suspension – 2-piece for maximum rear traction. Optional 1-piece provides increased rotation of the car in high-traction track conditions.
  • Rear of the REAR suspension – 1-piece for more steering and better rotation. Recommended for high-grip conditions only, as it decreases rear traction. When using ARS™ suspension, the alu rear lower 1-piece suspension holder must be used with #302201 alu brace post for ARS™.

The suspension holders are color-coated in a distinctive orange color. XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges.
