Hey guys. I've been reading a lot on here about sway bars and have heard good things about the cusco sway bars. I did however have one question. I've been reading a lot of people are just keeping the stock rear sway bar or running sway bar at all to prevent oversteer. Just wondering if the rear sway bar is necessary or not

 

The short answer is, it depends.

 

Ok well if I put both the front and rear cusco sway bars on will it result in too much oversteer? Or should i just stick with the stock one?

 

^^ it would depend on the roll stiffness the bars provide as a percentage greater than stock. If the bars increase both front and rear roll stiffness by say, 20% then the handling characteristics of the vehicle will remaining essentially unchanged with the exception of decreased body roll. If however, the roll stiffness increases the fronts unequally from the rears, which is almost always the case, then you may get more over/understeer depending on the thickness of the bars.

End of the day, driving preference is everything. Racer A could drive all day in a car set up for oversteer at 1 second per lap faster than Racer B, just because Racer A prefers a car more loose.

 

Ok so how do figure out how much the roll stiffness is increased so I can try and reduce over/understeer.

 

i can only tell that i went with Eibach.
their increase front/rear is pretty even compared to 2006-2007.

still i'm getting ovestear:

but as i said earlier my rear camber is small comparing to front - so after i increase it i may get this improved/eliminated...

so - it depends

 

This is what happens when you put on stiffer front and rear bars at the same time. You only made your car stiffer, but not stiffer in the correct direction to correct an issue.

If the OP has an issue with the way his car handles, which I doubt, he should speak up. Without having a goal or issue, talking about modifying the suspension is worthless.

 

I'm currently building my car for local time attack races and road course races. I was just wondering because of what people were posting on the official sway bar thread about some guys not even running rear sway bars at all. Just wanted a little more input on that

What Springs, Shocks, Tires, Sway Bars, and Alignment will all affect how the car handles. There are many different combinations that will result in a neutral car, the goal is to maximize tire grip while maintaining the balance to the car. What is the best way to do that is a matter of opinion.

One example is, if someone is running no rear sway bar and lower camber on the rear to keep the car balanced, then they are probably loosing grip that could be gained by running more rear camber and a rear sway bar.

 

I do not currently track my car, it is an 05, and on stock suspension (except rear lower tie bar). I am looking to reduce body roll and stay as close to the current condition as far as over/understeer goes. Question is do I need to get front and rear sway bars? I also see the cusco ladder bar which looks like it may be helpful, I am a noob when it comes to suspension and have not touched it bc of this. Oh I do have a Cusco cf front strut bar to hold onto when wrenching in the bay + it looks cool!
