Front Hubs - 2019 SOTU

Front Hubs - 2019 SOTU
From an Andrew Kidd Facebook reply. Deserves a searchable thread, maybe a sticky.
There are four viable bearing options depending on your budget and needs
1. OEM or OEM replacement (Centric Premium). Likely fine for most people who are reading this. OEM grease, OEM-grade ball bearings, proper machining on the backside.
2. OEM/Centric Premium, but repacked with better ball bearings. G10 is usually good enough and is better than stock. The rounder ball will more evenly load all the bearings and increase grease life expectancy. Better grease will tolerate the heat. This is time consuming and you risk damaging the seal, but it's not difficult. **
3. Mazdacomp Endurance (NOT TAPERED ROLLER). This is the same as option 2, but a professional has done all the blueprinting tasks for you. These are markedly better than option 1, and are usually enough for things like Spec Miatas or HPDE cars.
4. MiataHubs Billet Hubs. The beefcakes. For endurance race cars, or big-grip forced induction cars, or anyone who has tried option 3 and only had it last 20-30hrs anyway. If you whine about how much they cost, you don't need these.
**Centric has sorted their inventory and marked the BAD hubs with an “E” for economy in the part number. Don’t buy those.

Had to look them up just to see the price. $600 each, but they are beautiful!

However those were from a Timken hub, Shieuend (sp?) had issues with the OEM hub he was going to repack, so your results may vary.

13/32" rings a bell. I believe that's the size for the current 11-ball hub. The very original hubs the cars were assembled with in the 90s were actually a 10-ball design with a larger ball bearing, so make sure you know what you have before buying a lot of them.

$22 for a 100 *****. $5ish for ***** to rebuild 2 hubs.

I'm surprised that the BMW hubs hasn't been mentioned as an option. I know its still very new, but seems to show promise.
