Koni Sport Shock Absorbers are recognised as the king of shock absorbers for the MX-5.
From the regular 'Sport' units to the full 'Ride Height Kit' these really are the units of choice.
Fixed spring height, top adjustable for damping rate.
These are priced individually so for a full set you need to select two fronts and two rears from the drop down box.
