Hi, I some time ago, called low budget. They himmed and hawed around about answering the question on the type IV main beraing. Maybe stock, but way down the road for custom sizes. I believe my case is 20 over. In my heart of heart, I feel that bronze bearing is the way to go. Man pople continue to not want to get the type IV up and runnig. I do like the Subie, but a 3 liter turbo bug is my main quest. Jorge at EMS also stated that they were working on a type IV bronze bearing, but again stock first, bummer
