I was just wondering how they compare to the other brands....ford racing, eibach, steeda, etc.

Anyone have either series I or series II... I just got new 20" rims and wanna lower my car but wanna lower the front more than the rear. Anyone have any pics with these installed? Also is there a forum discount on either of these?

THANKS IN ADVANCE GUYS!

 

Well none of the other manufacturers release their spring rates for 05-09 Mustang springs, so its hard to compare the spring rates directly.

Their lowering distances can obviously be compared though. The lowering specs are all on our website.
