Update:

Did a search on realoem.com and here are the findings:

1) US and Euro shocks/struts w/ EDC are the same
2) Japan shocks/struts are different compared to US and Euro
3) Springs' part numbers are not available
4) Based on my rough "eyeballing", all other suspension components are the same

Conclusion:
1) BMW altered the strut/shock rate for the Japanese springs, hence this may show that when you change springs, it is best to alter the shocks accordingly as well to maintain the performance

Questions:
1) How exactly are Japanese shocks/struts different?
2) How exactly are Japanses springs different? Are they stiffer and shorter like most aftermarket springs?
