Here's a pic of Dan's double shock mount on his Optima Mid Custom:
He has the shocks on the rear, but it's also possible to flip the long bolts 180 degrees, and get the shocks mounted on the front. The main benefit of a double shock tower is much less impact force on the hole where the long bolt, that the shock is attached to, goes through the shock tower.
In this example double Optima Mid shock towers are used, for your car you would need the upper section of a ZR-R shock tower, to make the extra plate.
