There are plenty of replicas made in the same factory as the genuine items, but its pot luck as to what you can get.
Some replicas will be the same offset, the same alloy, same casting, same weight etc and even the same QC checks. Ideally you want soem that are TUV stamped/apporved particularly if you plan to go to Germany anywhere near a race track. Local police are stopping UK cars to check any apendages are TUV approved , so no cheap bodykits or alloys allowed !
Others will be inferior catings, different offsets (might foul/rub, or just cause tramlining if the offset ET value is 10 or more lower than the factory ones), poor paint quality etc etc.
As already stated you pays ya money.
