Chassis braces don’t really alter the way the car handles much. What they do is remove the variable of chassis flex from the tuning equation, allowing the car to be more precisely tuned. And this is the important aspect from a competition stand point. As being able to finely tune the chassis = better lap times. But in most cases you’re talking about a few tenths. So, on a street car this really doesn’t apply, as without a timing system you’re never going to notice if you were a tenth of a second faster in a given turn. DON'T WASTE YOUR MONEY
The benefit of chassis braces on a street car, to me at least, are more psychological. See, chasses braces also make the car "Feel" more stable, solid. This in turn inspires more confidence in the cars capabilities. Which typically causes the driver to drive the car, conscious or unconsciously, harder. Whereas the cars handling really hasn’t changed. The driver is just driving differently, which explains why people claim that adding a strut tower bar or a lower X brace somehow increased the amount of understeer the car has. When in reality, the car always understeered, the driver had probably just never had driven the car to that point to notice it.
Anyway. Point is for competition chassis braces are important to allow you to get those last few tenths out of the car. For the street they instill more confidence in the cars capabilities, for better or for worse.
