One of the major variations are some of the S13 are equiped with HICAS four-wheel steer. Like the S14, the S13 has a ‘passive rear steer’ design built into the multi-link rear suspension which uses soft bushes that deflect under load to change the steering angle. What the HICAS system does is to supplement this by actively deflecting the suspension using hydraulic rams. While the HICAS is beneficial for the larger part of handling, but it interference can be scarey when you are driving at its limits as it shifts the car’s geometry when you less wants it. This makes the car less predictable when driving hard which is not a good thing.

Hicas will actually have a 2" cylinder mounted directly behind the rear diff, about 8-10 inches in length, with “steering arms” hooked up to just behind the rear shock mount. It’s very obvious. If you don’t have these, you don’t have Hicas.
