I have not seen any references to "lowering springs". I do know that several LEAF owners have put Tein "Street Basis" coilovers on their LEAF:MrStian said:Hahaha! I am not used to this type of forum and was looking at the date people joined this forum!
You say that there is lowering kits for this car. But where can i find it? Have tried to search, but all i can find is how to lower nissan leaf springs, not the car!

In any case, I personally would be leery of putting lowering springs on a LEAF without also replacing the dampers.
And if I can find springs of the correct dimensions and rate for the LEAF, whatever car the springs fit would probably have aftermarket dampers available for it as well.
