Smokem Racing R12 roll centre shim sets

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.

Smokem Racing ARC R12 RS chassis plate

Smokem Racing’s new RS chassis plate for the ARC R12 offers reduced scrub compared to the factory chassis. By removing the short arm suspension mounts, the RS design eliminates excess material from the profile that’s no longer required. The new RS chassis also moves the holes for the rear suspension blocks forward by 1mm which allows racers who use ARC’s R12 ATS system with parallel hinge pins to maintain the same wheelbase by using no shims in front of the suspension arms, something that cannot be achieved with the factory chassis without modifying the suspension arms. Meanwhile racers who run the fixed rear toe suspension can maintain their stock wheelbase by using 2mm of shims in front of the suspension arms instead of 1mm. The chassis is made from high quality 2.25mm thick carbon fibre.

Smokem Racing ARC R12 top deck

Smokem Racing’s new top deck for the ARC R12, claims to find the sweet-spot with an overall width that is in between the 2 factory top decks. They then smoothed out the profile for more consistent flex characteristics and added the V-SES top deck’s trademark V-shaped cross brace, optimally shaped in width and thickness to deliver firmer flex in its stock form. This cross brace can also be cut to increase flex, just follow the V-shaped lead-in with a Dremel. This ultimately delivers four possible top deck combinations in the one product, allowing racers to fine tune their R12 exactly to their liking.

Torpine R21 shorty LiPo holder set

New from Torpine for the ARC R21 is this shorty LiPo pack mount made from brass. Weighing close to 80g in total, each side is attached with 3 screws and can be finely adjusted to fit the shorty perfectly. If 80 grams of brass is too much they have also released two additional weights that mount directly to the motor mount with one weight (8g) on the right and the set of two weights (2x6g) on the left. The threaded holes for fixing the weights are already in the motor mount by default and the weight on the right has the thickness to serve as the inner stop for the LiPo.

ARC R12 flex adjustment plate

From ARC for their R12 touring car is this new optional flex adjustment plate allows racers to adjust rear chassis flex by adding or removing screws at the 6 available screw hole positions. Precision machined from brass the plate adds 16g towards the rear centre line of the chassis which enables further fine-tuning of the car’s handling characteristics through weight distribution.

ARC release new brass suspension blocks & springs

Coming from ARC are new brass suspension blocks for the R12 touring car as well as a progressive 20mm shock spring. Starting with the suspension blocks, the suspension hangers are useful option parts to adjust and fine-tune the weight distribution while maintaining a low centre of gravity. Available are FF, RF, FR and RR blocks all of which are machined of heavy brass material with the whole set adding up to 21.5g of weight. The blocks can be used completely or as a mix and match with the standard aluminium hangers to achieve the desired weight bias setting. Also new and made for the R12 are 20mm C2.5-2.8 progressive springs. The red-marked springs can be used front or rear depending on the track conditions.
