iv heard that the suspention of a 90-93 (DA) teg is the same as the EFs...my question is should i use the ground controls for the DA on my EF for a stiffer spring rate?...will it handle better?...i know u can get custom spring rate for GC but it cost extra...someone told me that 500/400 custom rate is a good for autoX but is this too stiff for street use on the chassy?...by the way those anyone know the spring rates for the EF and the DA ground controls?..thanks

 

anybody??
