Xida damping video
NA/NB Xida race
These are short body coilovers optimized for competition. Ride height range of 105-125mm pinch weld. Wide damping range can be adjusted very soft for comfortable street driving, even with super high spring rates.
This wide damping range is largely responsible for their popularity among owners that daily drive their Miatas and occasionally do HPDE or auto-x on the weekends. Optional billet coaxial shock mounts.
NC Xida
These are unique in that the rears are inverted, to completely eliminate the stroke and shaft binding problems all other NC coilovers have. This make them cost a bit more but all dedicated motorsports rear shocks for the NC and RX8 are inverted. Like all Xidas, very wide damping range makes them comfy even with super high spring rates. Standard kits are 5/4kg Touring or 11/7kg Race. Youtube video for NC Xida. Standard billet coaxial mounts
ND Xida
Our Xida kit for the ND is available in three spring rate options, 6/3kg Touring, 8/4kg Sport and 12/6kg Race.
