how do i make the ls lighter more like the type r

instead of running a supercharger on my ls i think i am just going to put an r in there because i feel it it more reliable and meant for a beating. but how do i go about stripping weight off the ls

 

this topic has been covered a lot...you can search for more ideas but i say, lose the spare tire, ac, power steering, rear seats, floormats, privacy cover, you can get lighter rims and theres a bunch more depending on how far you want to go

 

if its a daily then theres no need for it
