Detailed Description

XIDA XL coilovers
90-05 Mazda MX5 Miata

Supermiata Xida XL
The new Supermiata Xida XL use the exact same shock technology, valving and materials as the original Xida Race. They are simply 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 range is roughly OEM height. We will typically recommend the sweet spot around 5.75" pinch weld on a Miata. 

The Xida XL stroke and bump travel are also roughly the same as OEM for SCCA EStreet compliance. This means that those wanting to run pinch weld heights under 5" will still want Xida Race, not Xida XL. 

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

Forum discussions about Xida XL:

Xida XL & Ace


The Gen2 Xida shocks are built for us by Tractive Suspension (Netherlands) and we spec Hyperco (USA) springs. The exceptional valving sensitivity produces both incredible grip over any paved surface and exceptional ride quality. Despite the surprising streetability, these are purpose-built racing dampers intended for use under the most demanding motorsports environments.
