Hello,

I dug deep to find the standard spring rates on Sierra and 2WD Sapphire Cosworth and I'am little bit confused about it:

If I get it for the standard springs:

Front:
Sierra: 106 lbs/in
Sapphire 118lbs/in

Rear:
Sierra: 264 lbs/in
Sapphire 286 lbs/in

Would you confirm those numbers please ?

If we compare to GAZ coilover we found:
GHA: front 300 lbs/in rear 180 lbs/in
GOLD:front 400 lbs/in rear 200 lbs/in

Basically, GAZ increase by 300 % the rate in front ?

By any chance, does someone know the spring rate of uprated GGR standard height spirings for 2WD Sapphire (GGR2247) please ?
