Hi guys,
Has anyone changed ur rear muffler to twin muffler from super circuit?  I'm going to change my rear bumper to EvoX bumper. Looking for rear twin muffler. Any comment?

There's are many factors. since when i got my car and after the scratch u see when the car was just few months old. I tried lots of stuff and brand to test everything that almost total cost me 1k+.
Tried kit at 1st, then turtle, then meguiar and lastly optimum with kc classes, and i can say u really special case with your white myvi that can last 3mth with those effect. its like your car nvr get bake under the sun with water on it or after come back from rain u go wipe your car nicely.
Even i got another car silver, seal, wax but the car butt always outside the porch, 1 week untouched zebra line come out and quite hard to remove. My quite hard is using wet cloth to wipe it.

i think u mod the most liao, among us, lol
apa zebra line

It depends. Cars with skinny tyres can cut through water better in the rain, preventing/less prone to hydroplaning. But cars with wide tyres can regain control easier in case of hydroplaning as the contact patch with the road is wider.

Hydroplanning if both car same speed, same force exerted on a spot by the tire, differ size but same brand and thread. I can 100% say both will hydroplan at the same time. yes its easier to control when u regain cos if the car slowdown or fast, depends, it'll up to the tire to give more force so that it contact with the road not water. so your better is like better when compared during dry but wet it depends on how much force the tire exerting on the road while preventing water slip in between the surface. the water will try to slip in between no matter how wide or  thin your tire is the force of water getting in is the same. unless your tire is like bicycle tire with or super wide tire that bigger than the water puddle.

Assume in a situation where both cars have tyres of different sizes, one wide another narrow, but both properly inflated.

The car with narrow tyres will have more pressure pushing it down on its' contact patch per square centimeter as opposed to the car with wider tyres.

What I'm saying is in the wet, narrow tyres can cut through water better at the same speed compared to wider tyres at the same speed due to this factor. So in a way you're right when you say that if the SAME force is exerted on the spot by the tyre, then both cars will hydroplan at the same time. But the amount of force exerted on this spot differs/reduces when you use narrower tyres.

It is a concept most understandable to women. Thin/skinny high heels vs. wedges. The skinny high heels have more pressure on the tip of it's contact patch, compared to wedges that have the pressure/force/weight of the person evenly distributed all over the base of the wedge.

and also science students..
pressure = force / area

Now I really have to rethink my choices.

i dont think it will come out in within 2 years time

That's y just now I say wideness plays a little role in hydroplanning.
Its like narrow(good cutting) & lesser grip when recontact on the road or wide(not good cutting) & good grip when regain contact.
Both stuff also like balance each another out. It all comes down to the thread that how good is it avoiding water accumulate under your tire.

Yes, thanks for correcting. Typing in a hurry. Bro, Friday night ok?

Huh? Wideness = whether the tyres are narrow or wide. So how does it play a small role?

Pros of narrow tyres when it comes to hydroplaning:

Cuts through the water easier due to the force (thank you, ziggy) acting on a smaller contact patch.

Cons:

Once hydroplane, hard to regain control.

Pros of wider tyres when it comes to hydroplaning:

Easier to regain control if the car hydroplanes DUE TO the larger contact patch/amount of grip.

Cons:

More prone to hydroplaning.

ASSUMING BOTH TYRES ARE OF THE SAME BRAND, AND WITH THE SAME AMOUNT OF THREAD/NEW.

So, yes. Pros and cons on both wide/skinny tyres. Kudos to bro junhowe for bringing it up.

Small role cause what's your conclusion at last? Both also got their pros and cons. its like 50/50 for wide and narrow.
When u go buy tire and think about hydroplanning factor, will take wideness into consideration factor since both tire got its own pro and cons. u wont cos u will go to the thread 1st. Excluding dry performance factor at the moment. U wont get the conclusion if just thinking wideness when hydroplanning is the main topic.

Actualy after all is said and done, i stil prefer skinnier tires because ideally i want to avoid hydroplaning in the first place. Furthermore, once you hydroplane, there is no telling what will happen before the tires recover grip, so no matter wide or narrow tires, once you hydroplane you be praying equally hard.

Prevent hydroplane = narrow tyres. But if in case does hydroplane = possibility of crashing and die.

Getting out safely from a hydroplane situation = wider tyres. But percentage of hydroplaning = higher.

I never did say that the thread is not important. If thread is not important I might as well just upgrade to 18 inch rims and get the cheapest 2nd hand worn out tyre I can find. Looks nicer too.
