I have a 99 Cobra with a P1SC seeing 8#'s and a T56. I currently have a 4.30 rear gear which I had before procharging. I am planning on swapping my IRS for a SRA within the next few weeks. The SRA has stock 3.27's and I don't think it will be enough gear for the centri blower, although I think the 4.30 may be too much. Any thoughts on what a good gear would be? Thanks.
