This is ARC A10-23 Car Kit (Aluminum Chassis).
The A10-23 is ARC's latest generation 1/10 electric touring car and it's ready to hit the track! Built on a completely new platform.
The A10-23 was developed with some key goals in mind - a lower center of gravity, increased mechanical grip, easy maintenance & setup and full adjustability.
Featuring a new one-piece upper deck, the A10 is super easy to drive out-of-the-box and suits a wide range of track conditions. An optional two-piece design is available to independently tune the front and rear flex for racers looking to get the most out of their A10.
There are 3pcs flex screw in front end and 2 pcs flex screw in rear, more flex screw mount on the upper deck will make less flex.
ALL NEW X-LOW SHOCKS
The A10-23 sees the transition from the previous Ultra Short Shocks to the new X-Low Shocks. The new X-Low Shock length is 7mm shorter than the previous Ultra Short Shocks. They also allow fitment of both ARC Ultra Short 20mm shock springs and the new X-Low 17mm springs. So there is now a wider range of springs to choose from to cater for every condition.
X-LOW FRONT SHOCK
The New X-Low shock towers are also much lower than A10. The front shocks on the A10-23 are 6.3mm lower compare to the A10. The new X-Low Shocks significantly lower the center of gravity and further improve corner speed.
X-LOW REAR SHOCK
The New X-Low shock towers are also much lower than A10. The rear shocks on the A10-23 are 6.5mm lower compare to the A10. The new X-Low Shocks significantly lower the center of gravity and further improve corner speed.
The anti-roll bars are located below the drive axle to further lower the CG of the car.
Adjustment of anti-roll bar tweak remains unaffected and can be performed by screwing/unscrewing the anti-roll bar ball stud.
NEW 5.8MM PIVOT BALL
The A10-23 outside pivot balls below the steering blocks feature a lower height of 1.5mm compared to the A10 design. This gives a larger tuning window achieved by adding shims between the pivot ball and the steering block. This allows changes to the steering behavior, with the less shims below steering block giving greater steering response.
KEVLAR TRANSMISSION PULLEY
Like all A10 series cars, the previously optional Kevlar transmission pulleys and diff case are standard on the A10-23. They help to reduce friction resulting in greater transmission efficiency.
NEW X-LOW 17MM SPRINGS
The new X-Low shock spring range offers 8 different spring rates - five linear springs from C2.5 to C2.9, along with three progressive springs C2.4-C2.7, C2.5-C2.8 and C2.6-C2.9.
All springs are color-coded for easy identification.
FULL CARBON LOW ARMS
The brand-new lower arms of the A10 are made from 3mm thick, high-quality carbon fiber plate and are stronger and lighter than traditional composite arms. The design of the new lower arms allows the arms to be moved further inboard for an even longer arm than the R12. Back-to-back testing has confirmed this new design to be even easier to drive while achieving greater corner speed.
NEW REAR LOW ARMS
The A10-23 rear suspension arms are 3mm shorter. In testing over a wider range of conditions, the shorter rear arms provided better steering response, improved corner speed and reduced front tire wear. With revised mounting locations, the rear track width remains the same.
NEW REAR HORIZONTAL BODY POST
The A10-23 rear body posts are now horizontal as standard. In testing, this delivers more consistent rear downforce with a wider range of bodies- there by offering improved feeling as well as consistent corner speed on the same bodyshell through the whole corner. The vertical body mounting is also available by using the front body posts on the newly designed carbon fiber mounting plate.
NEW CASTER GAUGE
The new V2 Caster Gauge R139004 is included with the A10-23. This allows for easy caster measure with the steering plate on the A10-23 now installed above the steering block platform.
NEW V3 UPPER A-ARMS
The new V3 upper A-arms now become standard on the A10-23. They are stronger compared to previous versions reducing the likelihood of the upper linkage from popping out after impact.
ALL-NEW ONE-PIECE MOTOR BULKHEAD
The new one-piece motor bulkhead caters for both upper deck designs, allowing different flex options via both the chassis and top decks. The bottom of the motor bulkhead now also features a 3mm center alignment pin to better locate the chassis when less chassis screws are used. This allows extra chassis flex to be dialed in with less likelihood of tweaking.
ADJUSTABLE UPPER ARMS
The upper arms are now fully adjustable on the A10. This means both camber and caster are fully adjustable. This means that dive and squat settings on the lower arms can now be set without interfering with caster settings - something that was not possible on the R12.
The upper arm base features 2 different length bushings to allow adjustment of the upper arm in 3 different lengths. Generally, a longer upper arm will give more traction at the expense of some steering response.
The all-new suspension arm design allows even more roll center adjustments on both the inside and outside linkages.
BODY STOP UPPER ARM
The upper arm now incorporates mounting points for adjustable body stops. This allows the simple use of a screw to act as a body stop. Using this allows the height of the body to be lowered while preventing the front tires from touching the wheel arches during cornering. This improves the handling characteristics of the car during hard cornering and aids aerodynamic performance.
The A10's rear suspension system now features an integrated the Active Toe System (ATS). This system allows the rear toe angle to vary during suspension travel, for further ease of tuning. By varying the angle of the ATS linkage, the amount of rear tow gain or loss can be varied to suit your driving style and track conditions.
The default setup increases rear toe during suspension travel. This further improves traction and corner speed with improved tire wear.
EASY ACCESS SPUR
The spur adaptor on the A10 is mounted on one side of the motor bulkhead, allowing easy access to the spur and belts. This allows for simple maintenance and spur replacement without removing upper deck and motor bulkhead.
BATTERY HOLDER INCLUDED
The included carbon fiber battery holder suits both standard and shorty LiPo batteries, with two corresponding sets of holes on the chassis for both types of batteries. Racers can either fasten the battery with tape or use the included adjustable battery retaining tab.
