DPE wheels.... My suggestion is to never buy american made unless it's HRE.... Trust me
That sucks to hear DPE seems to be getting a lot of attention lately, I've been to HRE's open house and the work is amazing also really cool guys as well...
This is the problem with US wheel companies, none of them own the equipment to cut the faces except for HRE. All of them hire out either to the one place in Florida, MHT in California, or China. MHT for a fact cuts the faces for DPE and ADV1 (along with a couple others). After that the wheel faces are sent out to a third party for powdercoating. Usually the barrels and lips are ordered when you place your order for the wheel because it is rare for a company to have them in stock. Then depending on the company, they either put it together in house or source out that process also. Mind you, this is also not taking into account if the company has their JWL certification.
If you truely want to find out if a US wheel company is good, I always advise on googling them or checking forums like m3post as an example. I'll just say my experience from the initial order to the problem I had has caused me to only purchase wheels from HRE, Japanese Brands, or BBS.
