^ never heard of them

 

Swift is a high end spring known in the racing world for its quality of construction and lightweight. Many racing clubs swap the coilover springs from other manufacturers and substitute Swift springs. To provide an idea of the quality, the Top Secret coilovers use Swift springs.

Here are a few links from My350z for further reference:

Has anybody tried Swift's G35 springs? From the specs it seems to be between Tein H and S.
