Using this adapters in combination with stock or GMS shims, you can run any spec you want. From an aggressive track/race alignment with front running -1° to -3° of camber and +5° to +6° of caster, to mild street -1° to -2° of camber and +3° to +4° of caster.
 
Adapters are designed to work with stock Alfa Romeo and GMS adjustment shims. 
 
This upgrade is suitable for any 4C owner, street, track, race use.
 
Wheel alignment is required afterwards.
