After riding for 600 miles on the Tanabe NF210 springs I can report that I am very pleased with them. The ride is just a little more harsh than the stock springs but the stock ride is not that of a luxury car to begin with. If you are looking for a sport spring to reduce the wheel gap by half and give you a little more road feel then this could be the spring for you.
The Tanabe DF210 was not tested on my iQ. It appears that the drop would be too aggressive for the stock struts and shocks.
