Gday Rick
I had a set of King Springs on my IS200, for the money they were pretty good, have since sold them after the sale of the car.
I have a set of Koni adjustable shocks on Ebay http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...E:IT&ih=001 which were with the springs, the set up with the lowering springs and Koni's was a good height, lowered the car 30mm and the car road and handled really well
Call me if your interested
