if you have the usdm fronts they are 223#, jdm rears are 217#- personally I think this will be a good combo spring rate wise- having the rear rates approach or even equal to the front dials out understeer- just look at the oe WRX rates to demonstrate the opposite 168 vs 117 rear

two potential problems I see, the USDM springs provide very little lowering ~ 10 mm, the jdm springs provide ~ 20mm on a STi, on a WRX you could see an additional 10mm of lowering

the other potential problem I see is that the GR2's might be a little underdamped for the job especially in the rear

that's IF you have mismatched springs
