If you are looking for a new racing touring car, ARC just released the R12.1 with 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.
Inheriting the R12’s superior stability, a new upper A-arm design allows the R12.1 to better maintain correct suspension geometry under harsh racing conditions. This delivers more precise handling, improved tire wear and better corner speed. New EX-short ball ends help to further lower the anti-roll bar height. The R12.1 also features a new spool design and kevlar pulleys.
All new C-cap blades featuring a harder material further increase drivetrain efficiency and durability. ATS is now standard on the R12.1. This updated system now includes 4 degree C-hubs as standard, with extensive R+D showing greater stability during acceleration and under braking compared to 0 degree C-hub from the previous ATS system. Rounding off the changes are new battery hold-down plates to make LiPo changes easy and tape free. The R12.1 upgrade kit contains all necessary parts for racers to easily convert their R12 to R12.1 specification.
