I emailed Dan at Diffsonline, told him that I'd use the car for a few events each year for 2-3 years, after which it would be a fun car for back roads and road trips, and asked him what he'd recommend. He said the Wavetrac with the stock 3.08 ratio.

I'd bought clutch pack diffs for a track car and a race car from Dan before and was confident he'd suggest something that would work well for my use case. Given how I was planning to use the car, his recommendation was what I expected.
