Front shocks (QA1 SA). The adjustment is at 0 clicks, full soft. Both front shocks using the same settings.
Rear shocks (Afco DA) set the same at 20 clicks comp, 10 rebound.
Both front and rear shocks adjust firmer by turning CW from full CCW position.
Range of the front shocks is 0-24 clicks.
Range of the rear shocks is 0-24 clicks comp, 0-39 rebound. Top knob for comp adjust, bottom for rebound.

RB preload is 1/6 turn on the rt side. Static weight on the RR is 786 lbs. (not updated)
Rear tire pressure at 9.5 psi. Front at 35 psi. 9.5 psi in the rear has been confirmed to be the best pressure to use.
New target launch rpm and boost level: 5500-5600 rpm, 160-170 kPa MAP.
