That 2.5" is not the body width difference, just the stance from different control arms. The bodies are the same (except of course the front bumper and fascia area, and the hood).From my understanding, the AEV flares do not give you any additional coverage if you put them on a ZR2. Seeing that the ZR2 is 2.5" wider up front than the Z71, adding the AEV flares should give you 2.5" added coverage, right? Am I missing something, like the ZR2 has different front fenders?
You could just get these for the front?
