Well havent sell my car and don’t intend to

But yeah once foam it’s for the lifetime of the car. The novelty only last few day until feel no diff or sit in another person car

Actually i dont think it was placebo coz i legit can feel my shocks working harder on uneven surface

But yeah the effect only last few day after u used to it

To me i dont think the price is worth it in hindsight but the effect is significantly better compared to that dick ring stuff ring
