Who makes the biggest rear sway bar for a 92' Accord?

 

bigger is not always better. Ask a few seasoned track racers and they will tell you that a bigger sway bar can cause more problems than a stock one.
But as for the biggest I would just shop around the manufacturers.

 

biggest one for that model year is made by Progress. However it is only 1mm bigger than the Suspension Techniques bar (I think 21mm v. 22 mm) So either one is not bad. The best set up for this car is one of these bars in the rear and brand new endlinks on the front with the oem bar. This is as close to neutral as you can get..
