B17. FRONT ONE-WAY AXLE
(Optional)
The Front One-way Axle (#802245)
behaves like a differential off-power
at corner entry and in mid-corner,
and like a solid front axle on-power
at corner exit. It allows the inner and
outer wheels to rotate at different
speeds under off-power conditions
at corner entry and sometimes mid-
corner. Under on-power conditions at
mid-corner and corner exit, the one-
way front axle locks up and acts like
a solid front axle, introducing some
on-power understeer.
With the front one-way axle there is no braking of the front wheels since the
front wheels disengage under braking.
The front one-way axle allows you to use slightly bigger rear tires than
front tires, and to have the rear wheels overdrive the front wheels. In that
situation, when the rear wheels lose traction the front wheels engage and
start helping to generate forward traction.
The front one-way axle can be used with either the standard rear gear
differential or the adjustable rear ball differential.
B18. FRONT SOLID AXLE
(Optional)
The optional front one-way axle can be very quickly converted into a solid
front axle by using the Front Shaft Locking Set (#802252). This set includes
two steel pins and a bushing. To lock the front one-way axle, insert the two
steel pins through the front axle and both drive adapters, and slide the alu.
bushing over the pins to secure them.
The biggest advantage of the solid
front axle is that the car brakes using
all four wheels, allowing for much
later braking than with rear wheel
brakes only (when using a front one-
way axle). This may require you to
adapt your driving style. Using the
solid front axle can be beneficial in
low-grip conditions and especially wet
or damp conditions. The drawbacks
to using a front solid axle are less off-
power steering, and the car becomes
more sensitive to tire diameter
differences. Overall, using the solid
front axle makes the car quite easy to
drive.
The solid front axle is used mostly used with the adjustable rear differential.
