XIDA XL Coilover 90-05 Miata MX5


Product Description

XIDA XL Coilovers
90-05 Mazda MX5 Miata


 Supermiata Xida XL are the gold standard for exceptional ride quality. They are the exact same shock as our legendary Xida Race, just longer — within a few millimeters of OEM length in order to function properly at ride heights (pinch weld) of 5.25″ to 6.5″. The high end of the adjustment range is roughly OEM height. We think the sweet spot for street ride quality and ground clearance is about 5.75″ pinch weld height.  

Note: We recommend using stock swaybars with Xida XL, GS, and Ace.

Xida XL & Ace

 The Gen2 Xida shocks are built for us by Tractive Suspension (Netherlands) and we spec Hyperco (USA) springs. 

Confused about ordering? If you are not sure which spring rate package to order for your project, give us a call or email. We’ll get the system matched exactly to your needs.
