This kit fits Honda Acura NSX (must be used with Koni) with Koni only shocks (the Koni shocks must be purchased from Ground Control, to be assembled at the same time. You cannot machine and assemble the kit yourself).
Ground Control works very hard with Eibach USA to make these springs to the standards that you demand. Lifetime guarantee on everything, not just springs. No excuses about ";racing"; or ";special";. If anything fails, while being correctly installed, it will be taken care of, period. We can only have a guarantee like this because every single part of the Ground Control Street coil-over kit is made by us or someone we trust. None of these parts are made in Taiwan. Everything is made in the USA.
