to stop here doubts about the sway bars...

What makes a swaybar stiffer ? putting the lower droplink more out or in ... ???

i always tought it was out ... but Belgium racers forum-members think it's in.. ??

 

Lifted from a sway bar site...."EVOLVE Anti-Sway Bars offer adjustability for precise tuning of your suspension to achieve the balance you desire during cornering. This is achieved using the two or three holes at the end of each Anti-Sway Bar. Inserting and bolting the end link to the outermost hole will “soften” the Anti-Sway Bar, while bolting the end link to the innermost hole will stiffen the Anti-Sway Bar and make it more effective. The positioning of the holes simply increases or decreases the effectiveness of the lever." .....

 

thanks ! ... but what does our friend Carl from928M advertise ? ...

These rear sway bar mounts eliminate the need for replacing your rear sway bar by moving the lower drop-link mounting point outward - thereby increasing the leverage your current sway bar has and making it stronger.



hoho, who's right ?

 

Barry,

if you put the drop link more in, then the arm length is less, hence less force on the sway bar, and less torsion. Less torsion, less roll. I think

 

Carl is moving the bottom of the link closer to the wheel. The Normal sway bar ajustments are being done at the bar....not the same

 

i tought the opposite.. the greater the moment arm is , the greater a body roll pushing will force torsion the swaybar ...

 

Think in terms of how much the bar must twist to allow the wheel to move. The longer arm is a part of a bigger circle so two inches of wheel movement is far less twist % than a short arm at the same two inches of wheel movement. And it is an antiroll bar with stiffer equal to LESS body roll. You "borrow" spring rate from the inside wheel to help hold up the outside wheel and keep the car flat. Crank in too much and you can lift the inside wheel off the ground !

 

aha! that could explain it ... going outwords on the lower drop link increases the rotation for a same body roll ... going inwords on the swaybar does this to !

Could be right... if one places his droplinks same amount out or in on the swaybar and wheels ... result stays the same... yesyes...

 

PM an e-mail address, next time in EU I'll like to stop by and see yr project.

Thanks and my compliments
