Tokico hts 102 installation

[Kamikaze]

Hi guys,

I wonder how Tokico HTS 102 Struts fit into Stock Strut Case, because they are slightly shorter than ADM Stock Struts.

I dont see anyone mentioned about these shocks installation in stock struts.

Which way is a better way to insert it?

1) cut the strut case (How long must be cut?)
2) put spacers (which size to match HTS?)
3) any more alternatives?

btw, does any one running on TRD spring F 6kg R 4.5kg?
I found that my rear height is slightly lower than front.... how is it possible?

cheers,
