Im looking into getting Sway Bars from ST and they offer two Set ups for the front...

I looked at their Products list on their site and they show the S4 having a thicker 1/8 thick front sway bar, and the S5 having a thinner 1/16 thick sway bar...

Suspension Techniques Products List and Applications

I wouldn't mind a thicker swaybar in the fron but I'm not sure how strong it is, and Im woried about understeer...

It says on the site on the sidenote that the S4's are adjustable but not the S5's...

Would anyone that has them know if the S4's adjust in stiffness and if the difference between the S4's and S5's are that notciable...

Thanks

Philip
