I always thought that it was more a tuner/ boy racer part. Because I was curious if it would do anything and if so, what would be the result?
I can say that I was very suprised to say the least! I combined it with the lower strut brace and it transformed the tire wear patern on my slicks in a great way. The tire wear was better and more consistent. This must have something to do with less strut tower flexing. It will depend from car to car if it works so good but on a 205 gti it works.
Only downside is the poor quality paint job OMP puts on.
