2011 Helix numbers?

I compiled a baseline for the Helix from many setups, and they all seemed to start here

The only thing I would add to that setup for your weight class, is make sure the RS seat strut is at least 4 in. off the motor rail, and the seat back 9 in. off the axle, the bottom of the seat about 1/2 in. above the bottom frame rail, and any weight that needs mounted mount it high on the side of the seat.
You will love the Helix

Helix is an Infiniti chassis, they have a section in Chassis
