Hello, I'm a week out from delivery of my first FFR kit and struggling to find any discussion of the two different gear ratios available for the T56. I'm getting the IRS with 3.55 rear end (planning on 18in wheels) and I've run through the gear ratio calculators but I guess I don't know how to properly interpret the data. Close ratio vs wide ratio for a 95% street driven car? At the end of the day I don't really care about fuel economy but I do care about driveability.

Unrelated, but has anyone figured out how the Gen 4 engine cover is supposed to fit on the Gen 4X? The mounting points seem to be off, maybe even the same as the gen 3?
