I've seen a good amount of buzz on Quaife and OS Giken, as to be expected since they're two of the best options in the differential segment but I've seen nothing on Tomei for the 370Z. It's about $200-300 cheaper than all others and offers options for Open and VLSD equipped cars, and you can select 1.5 or 2 way:

Why am I not seeing more on this? Is it too harsh/loud for daily driving? If you have one, please share your thoughts on it.
