I have Revinora front lip and rear diffuser. I have had great dealings with Oshin time and time again, maybe once or twice he took some time to get back to me but Oshin is ALWAYS professional and courteous.
The parts have been delayed at times but Oshin has came through both times. The carbon lip and diffuser I have are both a beautiful 4x4 weave pattern and figment has been perfect.
Two thumbs up from my experience
