Before it gets tainted and torn apart with inaccurate information from the general public I wanted to post it here to preserve the information in its original form
*PLEASE* do not post useless posts in this thread. Please keep legitimate relavant inquiries in intelligent form if need be so this can retain a professional and informative feel. Anything I deem relavant I can go back up and edit the post to include.

==Notes to be considered when selecting a swaybar upgrade==
-Stock swaybars are hollow as well as several aftermarket replacements. Testing has found the tube is the strongest shape and while maintaining a proportionate wall thickness a tubular swaybar will provide only 5% less stiffness for one made out of
solid metal in the same diameter but will have a significantly lower weight, sometimes a reduction as much as 10-20lbs. This has no heavy polar impact since its so low on the chassis but will impact braking/acceleration respectively.
-Adjustability is something to weigh in consider if thats a concern for you.
-Stock endlinks are actually very well designed but due to the age of the cars tend to have rotted bushings. Replace them with eurathane bushings from energy suspension kits, or the universal swaybar bushing kit available at local auto parts store. Note when using the universal kit the bushings must be sliced in half using a razor blade as they are twice as thick as what is needed.
- Whiteline swaybar blade type endlinks are not as well designed as the OEM supplied endlinks so that does impact the functionality vs stock links with eurathane bushings or aftermarket replacements. If using whiteline swaybars it is recommended that aftermarket replacements are taken into consideration
-Splparts.com produces a heim joint based replacement endlink solution for both stock and whiteline type bars. This will improve the performance of a swaybar by removing give/squish with bushings.
==Swaybay Bushings==
Energy suspension produces full bushing replacement kits for the 240sx so that all the old worn rubber bushings can be replaced with polyurethane.
