Lowering springs (SWIFTS)
 

I plan on ordering these tomorrow. When I read the description on "swift springs.com" the "spec-r" are the ones that fit for 370z & the "sports springs" are not labeled to fit the Z's. I was hoping to get the SPORTS one since the discription sounded like what I wanted.. Can somebody tell me if I cant use the sports ones?

The difference is pretty minor. I wouldn't get too caught up in the sales pitch. The difference in ride quality and performance is minor at best.

They only make the spec R for the 370z if you need a set we have them in stock ready to ship PM me!
