Tension, torque is something different. you Want Tension. as well if your frame is old, ( which all S13/240’s are ), you can get some pretty good sag, the preload, when setup at an alignment shop will help to bring the frame back into shape… IF this is just a show pc. then fine… but take a look at some of the other tower bars that are multi element I think you;ll find that instead of going from tower to tower with that setup if you triangulated and went from tower to tower and from tower to firewall you’d have a much better ’ performance ’ product… as well in th rear tower to tower but also tower to rear floorpan , again triangulated and preloaded you’d have a much better product. > [@4/30 meet @ Taffy's](https://forums.speedlife.net/t/4-30-meet-taffys/11080/136): > > BAS, sorry if this is a stupid question but what is preloading the bar? im guessing its adjusting the length of the bar so that the proper tourque is applyed to the strut towers in a neutral position? --- _[View the full topic](https://forums.speedlife.net/t/front-rear-strut-bar-design/103951)._
