TRC Valve Pistons

TRC has developed the brand new valve pistons to meet today’s very demanding track conditions.
Nowadays we are faced with high grip astro tracks, over multi-surface tracks over smooth glued tracks to loose and bumpy tracks…Key factor is to have the correct balance between compression and rebound damping in the shock absorbers.
The main feature of the valve piston is that compression and rebound damping can be adjusted separately.
So with the valve piston, compression can be harder than rebound or vice versa.
Let’s explain the two main differences in between the position of the valve:

Valve on the bottom of the piston: 

• Less compression damping compared to rebound damping. Slower rebound => more stability in high grip conditions.
• Valve underneath the piston in the front of the car will absorbs the energy
  on steep jump faces. The car will bounce less on take-off and stay flatter.
  
• Landing is more stable and especially when changing directions quickly, the car is more precise.
  
• The slower rebound reduces the 'jacking' effect on direction changes. Valve underneath the piston in the rear shocks of the car will make the rear end a lot calmer in
  edgy high grip situations.

Valve on the top of the piston: 

• More compression damping compared to rebound damping. Faster rebound => This generates more grip in bumpy and slippery conditions,
  as the wheel rebounds faster towards the ground.
• Specifically in the front: The weight will be moved more quickly from side to side: more mechanical grip at the wheels and more steering in low-grip conditions.
• Specifically in the rear: The car will stay higher in the suspension travel, allowing for a softer shock setting (and spring) to maximize its efficiency and grip.
