Ultra Racing (here: http://www.ultraracing.com.my/ ) makes a bunch of products that supposedly stiffens (reduces flex) the chassis. They sell various chassis braces and strut bars and sway bars that bolts onto various parts of the car’s chassis.
My understanding is that a stiff chassis a good thing, for good handling and for comfort–you want the tires and suspension to absorb the punishment of the road not the chassis. I want to be convinced by their claims but I’m also a bit skeptical.
What do you think about these types of products? Mostly a waste of money? Can you actually stiffen the chassis with something you bolt-on?
PS: This is what they offer for my car: http://www.ultraracing.com.my/Catalog.asp?Brand=Toyota&Model=Altis%20(2002)&page=1
