Eibach Sporline/KYB GR2 Front, sportline/oem shock Rear, problem?

[98TsiAWD]

I just bought a set of eibach sportlines and a set of KYB GR-2's for the front were included, no rears.

Should I buy a set of GR-2 rear shocks, or are they not needed?

Also with the sportlines, I will need a camber kit right?

HELP!

I need to know if I can use my OEM rear shocks asap. I want to put these on this week.
