I'm considering these Tanabe GF210 springs on a private sale. Part number is GDBGK, reportedly these are JDM spec Tanabe so I can't find much independent info about them.
The seller says these springs (GDBGK) and the TG092 have spring rates of 240lbs/in up Front, and 224lbs/in Rear, and that they lower the WRX approximately 1" front and 3/4" rear.
A healthy increase in rates for WRX but not overly stiff like the TGF107 which the seller suggests I won't likely need a strut upgrade as well right away.
I like that they are spec-C spring rates, but will they be suitable for my stock struts, or should I only install them with upgraded struts like the KYB - Excel-G items?
Will this amount of lowering negatively affect the suspension geometry?
