As with most great deals you give up some sort of convenience that will require more blood, sweat, or tears on the back end. That being said, the rear shocks bolt hole was considerably smaller then what the car required. Leaving me too bore out the holes To accommodate the original bolt. That was the biggest of my issues with the shocks, struts and coil overs. The coils are 60% of the size that came with the car. !ZERO INSTRUCTIONS INCLUDED!
