I just read on Suspension Techniques' website that their swaybars are solid, not hollow like most OEM ones. I have their bars... does anybody know whether stock G3 Integra bars are solid or hollow? That might explain part of why my car doesn't roll at all haha

 

DA swaybar is 22mm, and its nowhere near the weight of a suspension techniques 22mm front swaybar. id assume its hollow. i would guess theyre both steel.

i wouldnt put too much stress that hollow is so bad. torsion is a function of radius squared, so the inner portion is not as important to providing the strength. but yeah, a solid 22mm is going to be stronger than a hollow 22. the disadvantage is its much heavier.

also, if i was concerned about the cost of steel, id consider finding the right thickness and outer diameter to obtain the desired strength for least material. so its no surprise honda would design it hollow.

 

Well I'm not really worried about them, just interested in how much of a stiffness difference it would make. I'm really happy with mine. I remember the S/T bars being almost freakishly heavy but I don't remember what the stock ones feel like.
