Step 37 The kit setting is the No 1 strap spacer (1°). The spheres and inserts may feel tight to assemble, this is normal and some force may be required. The kit setup has the rear strap assembled with the writing facing up. This is a high pin setup (spacer under the fr strap). When running low pin (no spacer under the fr strap) assemble the rear strap with the writing upside down and the rear strap spacer installed. Strap spacers are for fine tuning the car for different tracks.
Step 38 Note the shape of the turnbuckle. This side is the left hand thread.

Car Settings Front Toe Toe out Front toe should be set to 0° (both front wheels pointing straight ahead) this will be the best setting for most track conditions. Adding toe out will increase initial turn in but make it smoother and easy to drive on power. The team generally run 1° toe out on Astro tracks. Toe in Front Wishbone Shock Mounting Hole The middle hole on the wishbone is the standard setting for most tracks. Moving the shock to the inner hole makes the car more reactive.
Car Settings Front Wheelbase Options Car direction The Car has only one way of adjusting the front wheelbase. Kit Setting Shortest Wheelbase Moving the hub carrier rearwards will give more traction at the expense of stability over rough sections of the track, and moving the hub carrier forwards will usually improve stability over the rough sections. 0mm offset Longest Wheelbase 1. The adjustment is provided by re positioning the quick clip on the outer wishbone pin.
Car Settings Rear Toe-In Inserts The base setting rear toe in is 4° this is a good compromise between forward traction and the car binding in the turns. This setting is fine for most tracks. You can alter the toe in by changing the toe in inserts. If you are running too much toe in, your car may suffer from instability at high speeds. Decreasing the toe in will reduce forward traction but will free the car up in the turns. Usually the team use less toe in on high grip tracks and more for low grip tracks.
Car Settings Low Roll Centre Lowering the kit pin height to pin low will give the rear more roll. This gives more side grip to the rear and more on power steering. If you are lifting a rear wheel going into corners then lower the pin or lay the rear shock over. Rear Wheelbase Options The Storm ST has 3 wheelbase options at the rear, short, med and long. The adjustment is provided by re positioning the quick clips on the outer wishbone pin.
Car Settings Slipper Clutch On most tracks it is best to start with the slipper on a LOOSE setting, and gradually tighten the spring tension until you achieve the most consistent drive away from turns without spinning the car or pulling wheelies. Make sure you still have enough drive when launching the car from the up ramps. WARNING, do not run the slipper too loose as it could melt the plastic spur gear, also too tight may damage the transmission parts.
Car Settings Variable Length Rear Wishbones The base setting is long wishbone. This setting gives the most on power steering and is the most stable on landing from jumps. The short wishbone setting will give more rear grip on loose surfaces. When running this setting you need to soften the suspension. Short Wishbone Long Wishbone (Kit Setting) Kit Setting Hex Width The base setting gives the best balance between steering and stability.
