Wow what a difference they made, Tein RS and Tanabe Sways. I went about 2" down in the rear, about 1.75 up front. Took it to Vegas the next day to break in the motor for the turbo install (needed at least 1500 mi) and played with the settings about every 50 mi. For the ride back I left them all the way soft for compression and rebound and it wasn't bad at all. Stiffer is how I leave it for daily drive to work, doesn't bother me at all but I don't know much about tuning them in. I was on stock wheels, but just got my Volk LE37 18" back from getting painted black/ polished lip so haven't installed them yet. I'll post pics of the install in a few days, car goes back to XERD this week to complete the install and test the Turbo
