**This package includes 8 pistons (4 flat, 4 bevel), all 5x1.5mm.  Nothing is pre-drilled.  We recommend the rear pistons to drill 2 holes larger @ 1.60mm which was the best during our 2021 testing with Kurt Wenger and Spencer Rivkin.**

This set is preferred by the Team Associated drivers with flat pistons up front and the bevel edge pistons in the rear.     Mix and match whatever combination you'd like for your surface.

The Schelle flat pistons are good all around for a more smooth surface, yet giving the car the added grip of the 5 larger holes.   The 5x1.5 base valving was updated in 2021 over months of testing and is ideal for hard bladder (waffle style like RC8B3.2) shock packages on outdoor and indoor temporary tracks or when you want initial softness and less progression (pack) initially.   For the rear suspension, we recommend starting with 2 holes 1.60mm, but for lower grip conditions we recommend drilling out a 3rd hole 1.60mm and increasing the rear oil to 42.5 wt or 45 wt AE.  

Updated in 2021 for hard bladder shocks.   What you'll notice on the track is the buggy is more plush on landings, less suspension flutter (especially in hot weather) due to the O.D. fit.   The faster rebound helps keep the tires planted and won't hop on landings.  

Hot Weather:
Front: 45wt AE (600 CST) 5 x 1.5
Rear: 40 wt AE  (500 CST) 3 x 1.50 & 2 x 1.60mm

Cold Weather (below 60F):
Front: 42.5wt AE (550 CST) 5 x 1.50
Rear: 37.5wt AE  (450 CST) 3 x 1.50 & 2 x 1.60mm

"I used the pistons today at the track with your recommended oils and my car was about 1/2 second faster around the track. The car was more plush with more traction. Thanks for the awesome product."    -Tim F.   (MakinTraxx RC, New York)   Conditions:  Track was dry and bumpy with a loamy outside.
