That suncore is a rear spring conversion from air springs. It is NOT a coil over. To the best of my knowledge, there are NO true coilovers for the rear for these cars. The mount is not strong enough alone, it is designed strictly for a shock. Stick the air springs and shocks for rear and the control arms and watts.
Adjusting the rear ride height is by sliding the height adjustment by small increments. (CV LX Sport exactly the same set up as Maraduer so dont' worry about that)
