The problem with most race seats is that they're not setup for wide people. I wear a 40/42 pant size and it seems like Corbeau is the only ones who makes decent seats for them. The good things about Corbeau that I've found out is that they hold you well and are comfortable. The bad, they wear quick (4-5 years was the average that mostly came up) and their brackets are junk.

The problem I didn't think about with an OEM seat is that I can't really have more than a 3-point seat belt.
