You need one with a strong base and a tower on it.

that does not answer the question of how?

draw a line between the 2 objects the bar is attached to? is it a vertical line? or does the bar a least mount in a 3 point triangular setup?

The horizontal line helps with the scuttle but does not with the suspension.

I loved my strut brace. Seriously loved it.

For leaning on, tieing things to, pretending it's a hilarious massive handle. So good.

It was worth every cent!

It was given to me. Currently being sold with proceeds going to a charity the chap supports.

If you too, would like a hilarious handle for your MX5, then you should buy mine.

I wasn't expecting it to do anything, and it didn't. However it looked cool. :mrgreen:

I'm trying so hard to not post in this thread, but it is a drug and I'm addicted.... Dupain, please do some more research (as suggested by others) you have failed to understand the forces involved and this leads you to make ill informed decisions and statements.

For example.... how these do not even discuss the type of suspension macpherson or double wishbane.

The variables are many here, but as a general rule – the strut brace allows more mortal drivers the ability to drive their cars closer to the limit by giving the car a more predictable and stable feel. A true professional driver would probably prefer a really stiff chassis, but could most likely turn similar if not identical times with and without the added stiffness (obviously there are extremes!!).

Now let’s introduce the front-strut brace. As the front strut-brace is a rigid beam, it effectively “absorbs” the majority of the sheering force. To see exactly why this is the case, Imagine a large glass table that is supported only on the edges. Setting a heavy object could easily shatter the glass on this table, but if we reinforced the center of the table with aluminum supports, the rigidity of the glass is no longer an issue. So just as the aluminum reinforcements effectively “erase” the lack of rigidity in the table’s glass, the same is also true when a front-strut brace is added.

Automotive engineers agree that increasing chassis rigidity imparts quicker and more responsive steering as a result of reduced chassis flex. Almost every racing car has chassis braces added or built in as original equipment for the benefits this rigidity imparts. Adding a strut brace to your family SUV or sedan will not make it into a race car but most drivers can perceive and appreciate the added rigidity assuming that a good quality strut brace is selected for installation, but it will not necessarily make your car faster.

The only valid and scientific method of measuring the effectiveness of a strut brace is to measure chassis rigidity before and after installation of a given brand of strut brace. The equipment that accomplishes this costs many millions of dollars and the car manufacturers are the only ones who are able to afford this equipment. Testing of chassis rigidity and methods to improve it are routine exercises at their R&D sites. Chassis rigidity is measured in units of Hertz in the USA and Newton Meters in Europe, these are highly scientific calculations.
