ARC have released this caster angle gauge designed for the R12 series of cars. Created to measure the caster angle, there are 2pcs inside the package, one for each side, with the height of the line marker adjustable to fit all setup station on the market.
Building on the already rapid R12 platform, ARC is proud to announce the R12.1, incorporating many new parts and improvements that elevate the chassis to a new level of performance. Retaining the basic R12 architecture, the R12.1 remains an extremely easy car to build and maintain. By removing mounting holes for the R11 short arms, the R12.1 chassis features a slimline profile for reduced chassis scrub under hard cornering. Made from 2.1mm carbon fibre, this chassis delivers added flex for greater overall grip and a wider tuning window.

Based on the successful R8S On-Road Pan Car platform, the new R8S-21 from ARC incorporates a number of refinements and option parts for even greater performance out of the box. The main chassis has been redesigned for the R8S-21 with the slots removed to improve chassis rigidity and handling with the original chassis linkage bars have been replaced with 2.0mm chassis flex plates for increased overall stability and traction. The optional body-shell mount plate is now standard and the front droop is now fully adjustable on the R8S-21. Also standard on the R8S-21 is the steel rear main shaft for increased strength and durability. The R8S-21 now only accepts standard 2S LiPo batteries with 2 different layouts available, laid down side-by-side or stood-up along the centre. Both layouts work extremely well but offer different handling characteristics to suit your driving style and track conditions.

ARC have released the R8.3E, their new 1/8th onroad electric competition car kit. Coming standard with a 5mm carbon fibre chassis which not only reduces weight but has excellent flex characteristics that delivers superior mechanical grip. The R8.3E transmission retains a 3-belt drive system through the centre of the chassis. The belts and pulleys are the same specifications as the R8.3. The integrated 3-piece upper deck connects the front bulkhead to the rear along with a fan mount for cooling the motor. The upper deck design complements the main chassis to provide optimised flex, but at the same time, reduces the likelihood of the belt flipping over the pulley. The new motor mount and a new internal ratio of 2.4, allow a wider gear ratio tuning window on the R8.3E from 4.75 to 5.85. The centralised battery position sees the batteries sit either side of the drive system close to the centerline of the chassis to improve weight distribution and lower the rolling moment. The R8.3E features new longer rear shocks that are 3mm longer than the previous model. This allows the shocks to be moved closer to the centerline for improved handling characteristics. Further improvements have been made to improve smoothness and sealing to deliver a more consistent rebound.

From ARC for the R12 comes these gear diff out-drives in steel. The new outdrive is made from spring steel and feature 2 different slots, meaning the new outdrive can fit both the bare CVD drive shafts or alternatively with the C-Cap blade. Sold as a pair.

Following an extensive design, development and testing program, ARC is proud to bring you the new R8.3 1/8th competition on-road nitro chassis kit. The R8.3 features and all-new internal gear ratio give it a FDR of 2.4, which improves acceleration making it great for small to medium size tracks, with the top speed remaining the same as the R8.2. The front end flex on the all-new chassis is adjustable by chassis cover, when installed the front chassis stiffens, increasing steering response while avoiding over-steering in high traction condition. The new battery plate also come with flex slot to increase chassis flex and stability. New radio tray and front bulkheads, the latter allowing easier maintenance for front one-way axle and belt. New radio tray design connects the front upper arm and creates overall chassis flexibility more evenly, making handling less sensitive with track condition changes.

Introducing the R12FF, ARC’s next generation 1/10th scale FWD touring car kit. Based on the 2020 ETS FWD winning R11F, the R12FF retains its front-motor, front-wheel drive layout for maximum traction under all track conditions. Featuring all-new long suspension arms to further improve traction and deliver more corner speed. Other new features include having the motor lowered by 0.5mm compared to R11F. The all new narrow upper deck comes standard as does the battery holder for shorty and standard LiPo. All suspension parts are comparable with ARC R12 and short front suspension arms can be used on tracks with very high traction. Optional flex adjustment plates for shorty and standard LiPo configurations allows chassis flex to be easily adjusted. Other standard parts include the horizontal rear body tower, while an aluminium chassis is also available for indoor carpet tracks.

Smokem Racing introduce their new carbon fibre roll centre shim sets for the ARC R12. Available in 1.0mm and 1.5mm versions, the shims are used to raise the R12 suspension arm mounts, allowing roll centres to be raised in larger increments without stacking multiple shims. Raising the roll centre releases the car from excessive grip through a corner, allowing for improved flow and corner speed. Features a unique design that allows the same shim to be used under all 1-piece toe blocks.
