16mm 5 Hole Fat Boys [2.7mm] Pistons- CUSTOM

**Sept 2024: This package is offered for customers who want to try one of the custom Team drilling options for different track conditions.  The baseline pistons are a good all-around. **

The Schelle Fat Boys piston lineup is built around the concept that a thicker piston will limit flow around the outside forcing oil through the valving holes.  For smooth and hot weather conditions, the 2.7mm versions are ultra thick, so the valving path is only 2.7mm tall, adding pack for hot weather and high grip.  Keeping the outside height 2.7mm makes the car that the suspension won't flutter, and can pack properly without using extremely thick oils.   The ultimate high grip and hot weather weapons, these are made to make the shock more consistent by using a thinner oil and creating more drag via the extended height.   The bottom side of the piston is pocketed to fit standard shock shafts.

OPTIONS (add into order notes on checkout)

1.  7 Hole Smooth Track:   Less larger holes in the piston, 2 tiny holes added for low speed grip yet give more pack on high grip tracks to really throw the car around with security.
2. Un-groomed Outdoor:   Further reduces pack over baseline, to handle lower grip and larger bumps for an outdoor ungroomed track.   Fronts add a tiny 6th hole for more steering, Rears have 3 holes drilled larger for less pack.

Testimonial:

"7 Hole Smooth track Schelle Fat Boys 2.7 are the best thing I've run at Thornhill.   I can really push the car and still have predictable grip."   - Chris Hatch
