I ordered the new V3R version of the quad fin diffuser for my charger RT & it doesn't cease to amaze me. The great customer service, the fast shipping(arrived in a few days), amazing fitment that is the closest to OEM I have seen. The material they use is super strong & rigid. No complaints here on my use of Vicrez! Awesome products, pure quality, & an overall great experience! I highly recommended to use their products.
