Fersa is Spanish based and while it does seem they do have manufacturing facilities there, that appears more for volume stuff, eg, current production vehicles. They may do their slower moving bearings there too, but they may not. I cant comment on their quality.
DPI too, I don't know of but are based in the Middle East (Dubai).
I did try a few years back a few after market brands as the cost of Timkens is rater high, however, I found the best bearing in these went for about 2500 km and the worst about 120 km. One even locked up (and others here have had similar experiences). Buy cheap, buy twice. To me, now there is only one brand of wheel bearings available for Mini - period. There are others that say they are, but from my experience, they definitely are not.
Thank you for the feedback. I ordered the non genuine for the rear because I really need to move the car and get it off the axle stands. The aftermarket is all that I can find from the SA classic mini parts suppliers. They can order the timken, it costs the GBP price you guys pay plus import duties, taxes and mark-up, etc. And would take 3 to 4 weeks to get here. That's just how it is unfortunately.
I'll probably order the timken at some point but for the short term, I'm out of options. I have timken in the front and the one rear has been on ball bearing type bearings for many years.
