I asked like 2 weeks ago that my 2007 yaris has lots of body roll and the most frequent answer was to add a rear sway bar. The problem is that I live in Spain and want to pass the tecnical inspection (ITV). If someone knows of a cheap bar with homologation that is sold/shipped to Spain for my yaris if there's any, or a rear sway bar needs to be homologated in spain? Also, if there were no sway bars available, changing the shocks while maintaining the springs is a good idea? and if there were shock recommendations it would be phenomenal

I have a 2007 Yaris and I love it, but it has lots and lots of body roll and I would like to fix it but I don't know what would be the easiest way, maybe a rear sway bar or some suspension set, what would be the easiest and cheapest way?
