My one-year-old Toyota Avanza 1.3 manual has clocked
12,000km. It has very high ground clearance which I do
not need as I have a small family and often travel on normal roads.
The problem is that the car is very bouncy and unstable
beyond 90km/h. Will it be more stable if we lower it?
Some mechanics said lowering the car will make it even
The suspension of the Avanza is quite basic, and while it can
be lowered, your "bounciness" may not go away.
In fact, it may get worse, depending on what is done to the springs. Normally when people lower suspensions,
they usually cut the spring coils and that will automatically increase
the spring rates and the bounciness. The ideal way to lower
would be to get special springs of the same rate but of a lower
ride height, but I do not think they are available locally. Anyway, you must remember that this vehicle has a van-like body
and is quite lightly loaded in the rear and susceptible to cross
winds. If you always drive with little load in the back, you will
have the problem of wandering, etc.
