Lockbar. For (as stated earlier) between $30 and $300 you can have a lockbar. Your HICAS light will stay on, but no more weird arse feeling in the back end
HICAS operates at speeds heaps lower than 80kph..... Fang it around a roundabout and you will feel it... The angle of (rear)steer depends on what speed you are doing at the time... Ie. If you are dawdling around a carpark, you will NEVER feel HICAS operating.... It will however operate above 30-40kph. At lower speeds the rear wheels turn in to aid steering and at higher speeds they travel in the same direction as the front wheels(depending on how much lock is wound onto the front wheels).
When drifting with HICAS you can really feel the rear wheels trying to straighten you out of the slide. It also gives you a really false sense of where the car is actually pointing...
Low fluid if it is pre Super HICAS
