"Chasses braces dont 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 precicely tuned. And this is the important aspect from a compitition stand point. As being able to finely tune the chassis = better lap times. But in most cases your talking about a few tenths. So on a street car this really doesnt apply, as with out a timeing system your never going to notice if you were a tenth of a second faster in a given turn. DON"T WASTE YOUR MONEY.
The benifit of chassis braces on a street car, to me at least, are more psycological. See, chasses braces also make the car "Feel" more stable, solid. This in turn enspires more confidence in the cars capabilities. Which typically causes the driver to drive the car, conscious or unconsciously, harder. Where as the cars handling really hasnt changed. the driver is just driving differently. which explains why people claim that adding a strut tower bar or a lower X brace some how 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.'
Any way. Point is for compitition 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...
+1Don't bother with chassis bracing until you've exhausted everything else:
Use the money to invest in some front camber bolts and a good alignment. Also, you can look into a bigger rear sway bar and a rear camber kit.
