13. Basic Wet Weather Tips
Most of the time, the dreaded rain comes and the change over from dry to wet setup is
rushed with only a 15-25 minute window to make the changes. What can be done is such
a short window of time? Actually, a lot, almost everything you will need to do.
Wet Conditions
-Wide the front hubs as far as possible
-Narrow the rear track width so the center line of the rear tire matches the center line of
the front tire
-Loosen the extra seat struts, you can keep them on, but make sure they are loose with the
nut barely attached (so it will not fall off)
-Remove the front torsion bar (and rear if you were running it in the wet)
-Loosen the floor tray bolts
-Adjust the front-end geometry to 4mm open toe-in
*This will be a very good starting point
Very Wet Conditions
-Wide the front hubs as far as possible (Install Longer Front Hubs if Possible)
-Narrow the rear track width so the center line of the rear tire matches the center line of
the front tire (Use shorter rear hubs 56mm)
-Loosen the extra seat struts, you can keep them on, but make sure they are loose with the
nut barely attached (so it will not fall off)
-Remove the front torsion bar (and rear if you were running it in the wet)
-Loosen the floor tray bolts
-Adjust the front-end geometry to 4mm open toe-in
-Raise the front ride height
-Install a softer axle or try raising the rear axle
-Remember if the track has sweeping corners, try the rear bar. It will lose efficiency in
the slower corners, but the gains in the long sweeping corners may offset the difference?
-Try to also raise the seat in an attempt to bring the driver's center of gravity higher
*This will be a very good starting point
! Notice the Longer Front Hub for added Grip!
