Because USA1 Industries is a criminal enterprise that takes your money up front, tells you it'll be 16 weeks, and a year and a half later you're still waiting. While LMC is a reasonably well-run operation that ships when they say they will.
USA1 has the best door panels by far. Unfortunately, they are a horribly run operation and as mentioned you will wait at least a year and a half to receive them (if you're lucky).
Looks great. Like I've said before, if you have the patience and can tolerate the criminal manner in which the company is run, you won't be disappointed with the quality of what you receive (if/when you do).
I think some people are getting confused with aluminum conducting electricity (yes, does so very well) with magnetism (nope not at all). Maybe because the whole positive/negative thing for both, I don't know.
@NickTransmissions Question for you. I have a 700R4 that is out of a 1989 Corvette. It is stock. What kind of HP/torque do you think it can safely handle? It looks like vettes that year were rated at 245HP and 340 lb/ft. The motor I have in front of mine is at about 360HP and 400lb/ft.
That is for sure. I bought a new Diehard battery at Advance Auto last night. Brought it home, and it was reading 10.5 volts. Left it on the charger all night. Then it read exactly 12. But I literally watched on the multimeter as the volts quickly dropped back to 11 after unplugging the charger...
Borgeson also sells the replacement steering shaft with the u-joints. Of course it isn't cheap, but I can attest that it is very high quality.

They're still making mine. It's a great motor btw. Roller cam, Vortec heads, over 350hp and 400lb/ft of torque. But man the price has gone up like everything. I think I paid 3 grand.

I have no experience to speak of with GM Performance warranty claims but I suspect there is little hope. I have had enough bad experiences with other warrantys where I was in fact still in the covered period.
I waited as long as I could to order my GM Performance crate motor, so I would have...
Do you have a set of vent windows that can be refurbished? I sent mine to Precision to be rebuilt, I'd say some of the best money I spent on my build. https://www.prp.com/vent-program
Even if you can find a used set to buy and send in would be better than anything aftermarket, IMO.
