I think you are misinformed. These $2000 wheels you are referring to, whether they are VMR, Vorsteiner, TSportline, etc are not fully forged wheels. They are flow formed or flow forged so they are often misrepresented as fully forged wheels. Flow formed wheels are nowhere near as strong as fully forged which is why they are so cheap. There are nice videos by Rays and Titan 7 that show the process of making fully forged wheels. Not that flow formed wheels are bad. They are fine for the street, but I wouldn’t use anything but a fully forged wheel on the track. To my knowledge, Titan 7 makes the least expensive fully forged 19” wheel which runs about $2700. My fully forged Rays Engineering Volk G25 were about $5500. 90% of the wheels shown in this thread are not fully forged wheels.
The least expensive fully forged wheels are the 19x9.5" Speedwell RS-1 which are right at $2k. LINK
Worth noting that the wheels are NOT 18.6lbs. They are 20lbs.
