Think of your engine bay as a box if you try to twist a box with no cover it will be pretty easy to twist(Bad cornering) but if you put a lid on the box (sway bar) This will stiffen up your box and your lateral movement in the car. But as you all know or some of you may know stiffer is not always better you have to find a balance bewteen front and rear suspension settings

If i udnerstand this right you guys are saying that by putting a stiff bar on the front you will make the front looser as far as grip goes.

I was wondering if some1 could provide a good explanation on how is it that tight sway bars that are designed to improve road grip and handling at the limit can actually decrease the grip when mounted only on the front.

I know for sure that a set of front and rear sway bars limits sway, increasing balance and keeping more of the tire planted on the road... so if the by just putting the front mugen bar on you are actually making the grip worse, then I am thoroughly CONFUSED.

Also, does the front bar make any difference is less that 'on the edge' driving and cornering? and how do the mugen and comptech bars compare...why is the mugen so much more expensive??

I don't think sway bars are intended to improve grip. Given the names which they are known by: stabilizer, anti-sway, anti-roll bars, I think their function is mainly to limit body lean. During hard cornering, the side-effect of the anti-lean function is that it tends to lift the inside wheel, thereby making it less effective as far as grip goes. So, it seems to me that sway bars are used mainly to find balance and not grip.

Here is one of the better explanations of sway bars and how they affect understeer and oversteer. It is long but worth the read.

Unlike the straight tie bars the sway bar is u shaped. Thus, it develops a spring loaded effect as vehicle weight pushes against it while cornering. The heavier guage bar withstands more tension and pushes and/or springs more weight back across the suspension. This lowers the limit of lower weight the car can transfer diagonally from both the front and rear of the car (because in a turn 2 points converge weight on 1).
The result is a more nuetral cornering with oversteer removed and the bar still soft enough (31 mm) to absorb understeer. At some point going past 31 mm the bar would become more rigid (less spring effect) and begin to push or cause understeer.
To further eliminate oversteer and roll, coilovers can be used to eliminate central and upper body weight from diving onto the suspension.

This also has an excellent description of how the brake system works: pedal leverage, master cylinder, compliance, pads, rotors.

Thanks!

The reason I was asking is that back in the day when I was buying new tires for my car from tirerack.com they had an article on how they added +2 wheels to a 328 bmw and then how they put eibach springs on and at the end the Sway Bars.

They said the sway bars completed the car's agressive handling transformation perfrectly allowing to run much faster laps...they also said the skidpad performance for the BMW went up as they put stiffer eibach sway bars on.

Is it possible then that but only putting the front Mugen on you are actually putting some of the rear "grip deficiency" onto the front wheels and therefore causing the fronts to go first?

Cause I mean i just see all the touring cars and stuff and they have ZERO body roll, granted its much better to drive the car when u stay horizontal thru turns it must have better handling characteristics too... im convinced that in some way the sways increase overall grip. mainly by but keeping the the tire-pavement contact patch larger and taking some of the load off the outside wheel...at least thats the definition i have read in a few places before.

so how is it that putting the front bar only on the stook can make the car so obviously understeer?

I WILL DEFINATELY READ THAT LINK THOUGH...cause obviously I'm full of questions.
Mugen Bar vs. Comptech Bar? why is comptech so much cheaper?

Also ppl are claiming this that X-Brace and Mugen bar is a huge help when it comes to keeping rear Bump Steer at bay...any1 back that idea up?


THANKS GUYS.
