In today’s competitive racing, the piston game remains a constant when tuning a high-end 1:10th off-road vehicle. The 2.3mm machined piston refers to the thickness of the actual piston giving an in-between option racers have not had until now. The pistons are made for 13mm diameter shocks with a tight tolerance for reduced blow-by giving consistent performance. The Delrin material, a hard compound with low friction characteristics arrives with dimples indicating an array of possible hole combinations drivers can alter to their own preference. 

Notes from the team: Thinner pistons created their place in RC racing with racers using this option at famous tracks such as OCRC during such events as the Reedy Race of Champions and the Surf City Classic. In the past, the stock setting for piston thickness was 2.5mm and later, 2.0mm thickness was introduced. Paul Wynn, using tuning to his advantage, has always looked for a slight change in thickness and the recommendation is now available to further dial into conditions.

In general, when the piston is passing through the oil, the thinner piston reduces the time the oil spends being restricted through the user generated holes in the piston. Although a small change, the moments difference alters the compression and rebound damping providing a different control and ride for the racer. Track time from team drivers Paul Wynn and Julien Oliveras have offered the drivers a smooth ride, bump handling consistency, a slight overall traction increase, and the ability to setup for jumps with more precision. Depending on jump difficulty, racers can choose pack settings with hole diameter and number of holes chosen.  It is recommended to always start with smaller holes for testing, making them larger is always easier and more efficient.

Starting point on dirt, drill 2 x 1.7mm front with 30wt and 2 x 1.9mm rear with 27.5wt.

Starting point on carpet, drill 3 x 1.5mm front with 40wt and 3 x 1.6mm rear with 35wt.

Features:
