apex+rear lowering

[avance70]

if i get the -40mm suspension kit, how much should i lower the rear torsion bar?
and how much if i choose the -60mm kit?

Depends how much weight you have in the back and if you have a lot of speed bumps.

15mm HIGHER than the front for best handling

road here is mostly bumpy
so like 20mm higher, or?
