Challenge has their own website, challenge-usa.com.

Send GTmotoring a PM, they'll give you a price and answer any questions. I sent them a PM a month ago and got a price quote, the OP is correct, you wll be hard pressed to beat these spec coilovers for the money.

I plan on getting these before the season starts in March, since the Tein's I'm running just isn't cutting it for track duty. I'm still trying to decide on what spring rates to get since I drive my car everyday. Decisions, Decisions...

Could you talk more about the range of settings that you use for track vs street driving. I have been talking to a lot of local coilover owners locally, none with the Challenge coilovers, but they all seem to be running almost full stiff, or only about 2 clicks from full stiff. These people do not track their cars. I ran a set of Tokico D-Specs on my last car, and often times ran them at almost full stiff, which was fine for the street, but I am sure once on the track, would not be stiff enough. With these Challenge coilovers, are you able to actually tune the handling of the car? It seems that most aftermarket coilovers, except for the higher end ones dont really let you tune the handling of the car. Can you ellaborate at all on the settings. Does each click make a significant difference? I see with a lot of these 16, 32, 36 way adjustable systems that people only use the stiffest couple settings? Are the Challenge coilovers different in that you really can utilize the majority of the settings? I know you will find your sweet spot that you and your driving style like, but can you really tune with these? I am asking because I worked in Speed World Challenge GT for a number of years and worked with Motons, SACHS, and Ohlins. I did a lot of data and shock tuning. I got very comfortable with tuning compression and rebound seperately. I am trying to be convinced that using only a single adjustable shock is going to be enough to make me happy. I will primarily be on the street with these, but am looking to start doing some track events in the near future.
