Up front, Fishtail uses QA1's upper control arm, while Tony fabbed up a custom lower control arm and radius rod to allow for more steering angle than the Mopar engineers ever worried about — needed so that Fishtail can hold more angle while sliding, which is limited by
the maximum steering angle provided at full - lock.
Not exact matches
The
steering, lifted from an R8, responds promptly and accurately, but the
maximum permitted
steering angle, half a turn, is only just enough to describe a grand arc from the departure to the arrivals terminal.
At the highest lateral accelerations, near the physical limit, AHK reaches its
maximum rear - wheel
steering angle of 2 degrees — ten times more than the passive
steering provides!
That means everything from the ride hight to the spring rates, the (rear)
steering angle, the
steering feedback, the engine and gearbox response, the brakes and the all - wheel drive's multiple - direction torque vectoring will be set to give you
maximum speed and the most comfort in any given situation.

The stabilization system ensures
maximum reduction of the roll
angle on bumpy roads in both a straight line and around corners through active decoupling of the stabilizer halves, while ensuring the most agile drive and responsive
steering.
The
maximum steering wheel
angles - an indicator of
steering effort - were reduced during the obstacle - avoidance test by 22 percent on average;
steering wheel
angles of more than 180 degrees, which force the driver to move their hands on the
steering wheel, were eliminated.
At
steering angles near center (for example, when driving straight ahead), the ratio is slower, providing
maximum vehicle stability for highway speeds and straight - aways.
Benchmark performance and
maximum driving involvement are guaranteed by immediate turn - in, with smaller
steering wheel
angles, and increased cornering speed.
