You are looking at low pressure cast wheels vs forged wheels. Very different.
It is a very popular style. Also look into BC Racing wheels, DPE, ADV, and HRE. They all carry a similar 10 spoke style at different prices. Really what it comes down to is... You get what you pay for. Cheap wheels = cheap quality in structure and build. Keep that in mind.
Many vendors here offer these wheels at great prices. Check them out. Like PYSpeed or sonic tuning for example.
