Whats the dif. between 50/50, 70/30, and 90/10 shocks/struts

[srv1]

what it means on a 90/10 shock is 90% compression, 10% rebound. A shock that has 90 percent of its total stiffness in compression control and 10 percent of its total stiffness in rebound control is referred to as a "90/10" shock. Remember, this is the characteristics of the shock, not the stiffness rating.

So what a 90/10 shock will do is allow the front suspension to "droop" or let the suspension drop when you accelerate. When your weight transfers from front to rear, it allows the front suspension to move more freely and when your weight transfer starts to stable out (like coming off a wheelie and hitting the pavement hard) the weight of the front of the car is at greater force so you will need to have more of the shock do a compression since the suspension will be compressing more. Hope that helps.

To make it easier, remember push=compression, and pull=rebound. Take the shock and push it. It will be harder to compress at a given rate. now pull it, it wil be easier at a given weight.
