I had tokiko illuminas and sportline springs. The car handled like it was on rails and it looked sooo mean slammed to the ground. The illuminas are 5 way adjustable and I could feel the difference when I would adjust it. As for ride quality it was very close to stock setup imo. My only problem was I couldnt handle hearing my car scrape against the ground every time I ran over something higher than 3 inches off the ground, it would make my whole body cringe every time. I finally replaced it back to stock when I put a huge gash in my exhaust and dented my oil pan. I still have them sitting in my garage with a front and rear camber kit that I plan on selling after Christmas.
