suspension help

good day,
have a set of JIC coilover for my cefiro A31, they came from sylvia S13s. problem is, the spring rate doesnt match the cefiro since the cefiro has bigger body and heavier engine. i have rb25det in it.
i like the set-up to be street and tracks

if anyone can help me set-up my suspension?
any help would be appreciated

thanks

well me hating JIC aside. JIC, Swift, Tanabe, Zeal all sell springs that should fit, however you will probably want to have the coils revalved for the different rate. (which JIC more or less does)

I dont know much about Cefiros besides they're JDM cool as hell so I cant tell you which rate to use. it would probably be best to copy a top tuners rates but 2kg/mm on each end would probably be more than enough to stiffen up the front to control the weight and enough on the back to get some rotation.


P.S. if your rolling on some wide ass dorifto rims I want Pics.

yea i want pics regardless. Its fun seeing cars that arnt here. I want a chaser so bad. For some reason i love em. THat would be my ultimate family sedan....

I want my next car to be something big and VIP.

I know if I can find a way to get a 6-spd in the Aristo (GS300) then Im on it like white on Rice.
