I own a 04' cobra that already had a SRA installed before I purchased it. I am curious to know, what does the SRA come out of? I have seen alot of posts of SRA's coming from Mach 1's and possibly Gt's. I would like to get some clarification on this, as I am also looking to purchase some other wheels for the vehicle, is there a different back spacing / offset etc. that I need to look at? Sorry if this has been posted before.
