Corolla Update - Strut Mount

Brought the Corolla to an annual government inspection. Passed.

Replaced a pair of the front suspension strut mounts. Some clunking suspension noise is now gone. And magically the ride seems to be improved (smoother and more fluid) and the handling sharpened by a slight and yet perceptible amount. In the end I feel positive. This Corolla strut mount comes with two layers of hard plastic sandwiching a rubber and a bearing. It is more complicated than and has more function than I expect.

That's the product description for the strut mount: "Optimizes steering and suspension performance by acting as a pivot for the steering mechanism; Reduces squeaks, rattles, and vibration noise."

Also at the same time I have replaced the right side universal joint/drive shaft. It is quite expensive and a lot of work. Somehow it is better but need to test if grinding noise when during right turn still exists.

The most obvious change to me now is the steering. It is direct and fluid. There is an increase in the connection between the steering wheel and road. The vagueness ia gone. The conner limit has somehow increased, despite the ridiculous ride height. It is good that I can always lower the ride height to sharpen the handling without a change in ride quality.

Simplicity of the Corolla

The simplicity brings joy.

The joy comes from two areas: the car itself, and more importantly the driving and experience of owning it.

One will have to fully appreciate Corolla's strength with tons of driving experience in other cars, and to a fuller extent with other cars in ownership.

Excitement and curiosity often mask the inconvenience and trouble that follow. This joy of owning a Corolla excludes mods as such. My only want is to restore, not mod. So in a way the Corolla is free of such trouble and inconvenience. Its limitation now becomes its edge.

So what is it like if the Corolla is replaced by a C36?

Brake Kit Upgrade for SLK350 (future project)

This would be the last item before the body kit.


The monoblock AMG 6-Pot and the 345mm floating disc are very tempting, not only because of the look through the wheel spokes, but also stopping power that the SLK350 much needed. I can account this under safety and handling department.


But the thing is once the 6-pot is installed there is no going back to 17" wheel without taking the brake kit off. This is indeed a reduction of option. I have a little reservation. And by not doing that I am always tempted.

R171 3-link Front Suspension

Jumping from C36 to R171, I keep wondering about the change of the front suspension. The traditional double wishbone gave a firm and luxury Mercedes ride to the W202. Because of the split installation of spring and shock, it gives a rather stable platform which are strong and reliable. The 3-link strut type came to W203 with a surprise but it did have a much sharper turn-in and responsiveness. While the lower arms are split and deem less stronger in construction, the strut itself tells a different story. The strut is heavy and over-engineered. The trailing front arm would help handle the impact of bump thumps and braking (a pull force), while the lateral arm defining the lateral position and dealing with the lateral force during cornering. It is funny that Mercedes engineers decided to use the steering (tie) rod as a third suspension arm which sits about the same levels with the other two lower arms.

The Thought of Adding a 4th Project Car

This is not entirely a sound idea at all. However the temptation to do so lingers on. 
I have always been in search of a fourth car which is special. I would want it special because it itself must bare a strong justification for its place, competing against my other cars and my guilt (of spoiling myself).

To own the fourth car I must be ready to ditch one of the three existing cars. The likely one is the Corolla which I like a lot, as both a fun car and utility car. 

To ask the right question is important to determine why I need a project car and which project car I will take on.

While getting a project car can be easily justified, getting a fourth car isn't. It is an excess and easily a baggage. Keeping three cars are already a drag. Keeping four would be unwise if the justification is utility related. And then there is the drain to keep the fourth car, along with the other three, at tip-top condition.

So this fourth car got to be very special for its own worth, and must bring a lot of fun, expected and unexpected, as a project car. Financially it would not be a burden, while low initial cost is not necessary if recurring cost, mod cost and resale are taken into consideration. And there should not be any surprise towards the negative end.


Added on Feb 15th, 2011:
Somehow I feel that a project car is a sort of materialistic bondage. I am not saying freedom is good and then bondage is bad. We need certain level of bondage to feel materialistically satisfied and our desire met. But too much of a bondage at certain time can be bad, and easily catches one off guard. So it is important to be very cautious, as a project car, and a fourth car, can easily drain more than one would expect, and can interfere with other aspects of life in the form of a burden.

SLK350 Driving in the rain

This would be the first time I drive the SLK in the rain all day in all kind of wet surface. The traction has been excellent, and the ride has softened up a bit either because of wet surface or softened suspension (just fitted over 2 days ago). The ride, feel and handling are very factory-like.


And the roof holds up quite well, all day in the rain and no leaks.
