The ISO's yea you can. You can see in my sig pic, I only kept the bottoms, car sits alittle lower. Next time I have them out I might take out all the ISOs.
Looks familiar, I've got the same setup although my springs settled a long time ago. I love the looks of a spacer on my rears and they get tons of compliments.
Instead of using spring iso's just go to the parts store with one of the springs and find some fuel hose that barely slides over the end of the spring. No squeaks and it will sit lower than new spring iso's.
Your car looks dope! I will lower car immediately if I ever get a flat driveway
I also run 1" spacers, makes a nice visual difference. Props bro nice ride!
