BC7 coil springs



Disassembled frontal suspension coil spring showed color definition codes with different painting after removing under coating material layer. Left side had yellow and blue and white and orange colored promptly. Consulting on service manual, the former was for RS model and latter was for Ti, how come? Different coil spring strengthened ones were set on both side?  This kind of must have been invited based on the concept of the actual use, driver side stronger coil spring to keep the car attitude flat without leaning to the left(driver's steering side). Discussing about this phenomena, different strength coil spring setting had been done since over 40 years ago, in addition, US drivers are not always thin men?
Consequently, stronger coil spring with yellow and blue painting colored would be set on the left side.
On the other hand, rear coil spring color with white and orange revealed that they were for stronger RS model. Hitting part shown on the surfaces with rust would be eliminated by grinding avoiding rub sounds.
Original setting of coil spring property would be appreciated by admiring the technology of factory research and developing engineer's concept done over 20 years ago, if my own desires come out in my mind.
