Thanks for the continued info on the retrofit, aajami. I still wish we could gather more information on this:

Front: are the struts dimensionally identical, including the lower spring perch? Tom seemed to suggest that they are, but you seem to say that the lower perches are lower?

If they are dimensionally identical, then the lowering is completely due to the spring, most likely a shorter spring which results in less pre-compression = lower normal position. The springs could also be slightly stiffer but not by much; otherwise it would offset the the lowering effect of the shorter spring.

Rear: obviously it is a non-coil over, therefore all lowering is achieved by the spring. Question is: are the rear shocks dimensionally identical too? What about the bump stops and upper shock mount? Can you confirm?

Thanks
