Can I reach 12's without this mod or is it a necessity?
Mine are still stock , It is def worth doing , but not mandatory IMOP . I would like to know if any one has done before and after testing ?
i will probably be doing mine shortly, and take t to the track after. however i don't think that will be the best judgement... ill have to do some logs
I noticed nothing in the logs or at the track
