Valuable TOOT value

The critical problem was found on steering reaction while turning at parking speed on BC7 SUBARU Legacy LSi US model, this is why I had replaced suspension coil springs and shock absorbers from original US specification to GC8 WRX GDB model's ones, leading to suspension height reduction as low as 40 mm. As a matter of fact the steering linkage and knuckle ball 3 dimensional position had been changed from originally designed one to uncertain and unpredictable situation. Probably TOOT value must be at ugly one causing braking effect while turning if the wheel alignment at straight running phase has been established in suitable condition.
First of all, careful checking and scaling must be performed on the difference of 3 dimensional ball joints positions promptly before replacing back the coil suspension springs as they had been in US designing. The most shortcut would be original coil spring to regain the original suspension height leading to re-establishing the factory designed originally 3 dimensionally correct correct relations even in dynamic movement. High performance tire with fine gripping property has zoomed in this kind of inconvenience.
The original coil spring and WRX dumpers would be a better choice, rear strut upper mounts are those for initial generation being different from later models, upper mount and upper spring holding plate are in one piece. I have no emotional resistance to rise up body height as US standard, because I have enjoyed enough lower one in this Legacy model. I want some gentle drive feel because of my age.
I'm going to solve this problem from now.
