Here are the alignment specs for our cars

Front
camber -0.4 to -0.9
caster 7.4 to 8.4
toe 0.00 to 0.08

Rear
camber -1.4 to -1.9
toe 0.08 to 0.25

my car after the springs:

front
camber -1.3/-1.2
caster 7.5/7.6
toe -0.44/-0.44

rear
camber -2.4/-2.3
toe 0.23/0.53

after new alignment:

front
camber -1.2
caster 7.5
toe 0.04

rear
camber -1.6
toe 0.16


Just FYI so just doing the Techart springs you can achieve about -1.6 front and -2.5 rear camber, which is IIRC the GT3 alignment specs
