I run the illumina's with ST springs and sway bars. I think this combo is a nice upgrade over stock. There are certainly better combo's out there for extreme handling, but for just something better than stock, this works great. I also had a HKS tems controller. Although the controller was neat looking, it really was just for show. A small full hard mod is not hard to do and just as effective as the 350 dollar HKS controller.
HKS makes great shocks for tems. The ride quality doesn't suffer at all but on hard with some good tires... Better have good seatbelts! The shocks with springs and controller is the setup I have and I wouldn't trade it for the world! Just my .02
