What's good on one car often doesn't mean much because next guy is more aggressive, tires stick more, etc.
Sorry but If you can't trailer/tow then carry tools and parts to replace dead hubs etc.
No warranty covers Racing and most don't cover commercial vehicles.
Like GM made Fiero Cheap... Most parts venders make parts as cheap as possible. Many times aftermarket hubs can fail in normal driving. I have one that died in a few months driving to work. (I save it to see why... http://www.fiero.nl/forum/F...HTML/127848.html#p21
Most/all Aftermarket rear use taper roller bearings.... OE is ball bearings.
Rear hub can fry the bearings or break otherwise. Can't find the thread where guy had broken the wheel flange...
Yes, Sticky tires often puts more load on the hub/wheel bearings for making a turn. Even OE tire sizes w/ better performance tread compounds puts extra load on the wheel bearings.
Vender sells TRW brand parts? Problem is often one company makes the hub for most brands. You get same iffy part but price and warranty can vary widely.
Made in US is safe?
You need to read US Customs etc for rules what terms mean.
Hub makers can legally
say Made in US and still have Chinese Bearings.
If anything says Assembled in US... Most to all parts made elsewhere and small amount of work to assemble the pieces.
Example: Many says Cree LED bulbs are US Made. Wrong. Package says Assembled in the US. Is a Big Difference.
Never preload Fiero front bearing! You will kill them doing that.
See my Cave, Front Bearings
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
