Do they make any products for stiffening the rear suspension for a 2002 Honda Accord 4 door other than thicker sway bars

 

You mean spring wise or chassis wise? You could get stiffer springs or even coil overs. As far as the chassis goes there is the sway bars, strut bar, and maybe a company makes rear braces.

 

Yeah Chassis Wise... I know about the springs,coilovers, strut bars, and sway bars... But what i was really looking for where the stuff like what you said the rear braces but i couldn't find a company who made them for my car
