The only cheap way would be to run Tein H tech lowering springs because it's an ITR replica except "Stiffer" I believe.
It's a very minor drop though & still you will run the risk of blowing those.
Everyone, S tech is almost a 2" drop. That will blow stock or OEM replacement shocks/struts.
Tein says 1.5", but it's closer to about 1.7" or more.
Ride quality will suck too.
There's no cheap alternative that will be reliable.
