Thank you. You have rated this product.
Ride height is adjustable from stock to 2" lower and more. All aluminum CNC manufacturing makes for light weight parts with smooth and precise adjustment. Performance shocks are recommended. Hardcore CSP kit, 99-05.
These drop ship direct from Ground Control and they consider this spring combo a custom order spring rate which means you should assume about two weeks ordering time if we don't have it on shelf (feel free to ask).
Also, note that this non-standard rate Ground Control Kit is TOO MUCH spring for standard off-the-shelf Miata KONI sports or Miata KYBs or Tokicos. You can either use our Miata KONI RACE shocks which are on this website or you can have standard Miata Koni Sports re-valved for the purpose. TELL US IF YOU DON'T HAVE KONI SHOCKS!!!!
