New rear shocks

.75 inches shouldn't matter, but what is you intended use of the car. I don't recognize that brand of shock. To me it looks like a cheap shock advertised in a performance catalog for a hot cheap price. If you want to spend about $40 buy KYB's. I think kybs are a little harsh. If you want a really good shock buy bilsteins they are available from firmfeel.com for about $100 each. I know that sounds like a lot of money, but do some price shopping for a shock for a newer car like an avenger,taurus,camry,accord,etc and you will see that $100 per corner isn't that bad.
